INTRODUCTIONTo reduce the cost per cubic meter of dredged material the ship builders in the last years
have turned their interests into building CSD (Cutter Suction Dredger) and TSHD (Trailing
Suction Hopper Dredgers) of large dimensions The evolution in the 60s saw installed
diesel power of 10000 kW to reach 13000 KW of power in the 70rsquos to then continue in the
80rsquos with 15600 KW of power to 20500 KW power in the 90rsquos growing to 22400 KW of
power in the 2000 to eventually reach a power of 27000 KW in the year 2015
The Safety Coefficient is determined according to the class of the raw material and the
conditions of the network Networks and all calculations are made according to this
coefficient
Safety Coefficient is C=125 for potable water distribution lines

ABRASION RESISTANCE
In the near future dredging work will be
characterized by the production requirements (large
volumes at low cost) and by the geographical
peculiarity and the climatology of the sites to be
dredged (temperature climate storms waves
escape ways etc)
Only the large CSD amp TSHD will be able to meet
these types of job requirements
Currently the dredging fleet in the world includes
about 40 large CSD-TSHD
To meet the increasing worldwide demand for high
pressure and large diameter discharge pipes
KIASMA has developed innovative HDPE piping
systems for the dredging industry able to resist to
pressures much higher than 10 bar
RAW MATERIALThe raw material used for the production of polyethylene pipes is classified in MRS (Minimum
Required Strength)
MRS is the strength value of the material against
the inner pressure along 50 years of work at 20deg
Verification was carried out subjecting the test pipe to 400000 cycles
Pipe is filled with water and a percentage of 30 of various types of inert (sand gravel
rock) The result is the following

while laying HDPE (PE80 PE100) pipes In
the case that the temperature is increased
elongation will occur in length and
contraction will occur in case of decrease in
temperature
At 1 m of PE pipe for temperature variationfor each laquoKraquo number (1K=1degC) 018mm
elongation or contraction will occur
∆L = α x L x ∆T (∆L =m k mmmK983085983089 )
For instance in case of elongation or
contraction dependent to temperature in
length in a line built with PE piping pipe will
move from the turning point instead of the
fixed point Assume that for a 12 m pipe
normal operating temperature Tv= 20degC
maximum pressure T2=10degC According to
this variations in length dependent to
temperature are calculated as follows

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within
values does not damage the pipe

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

FISH FARMING
HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

INTRODUCTIONTo reduce the cost per cubic meter of dredged material the ship builders in the last years
have turned their interests into building CSD (Cutter Suction Dredger) and TSHD (Trailing
Suction Hopper Dredgers) of large dimensions The evolution in the 60s saw installed
diesel power of 10000 kW to reach 13000 KW of power in the 70rsquos to then continue in the
80rsquos with 15600 KW of power to 20500 KW power in the 90rsquos growing to 22400 KW of
power in the 2000 to eventually reach a power of 27000 KW in the year 2015
The Safety Coefficient is determined according to the class of the raw material and the
conditions of the network Networks and all calculations are made according to this
coefficient
Safety Coefficient is C=125 for potable water distribution lines

ABRASION RESISTANCE
In the near future dredging work will be
characterized by the production requirements (large
volumes at low cost) and by the geographical
peculiarity and the climatology of the sites to be
dredged (temperature climate storms waves
escape ways etc)
Only the large CSD amp TSHD will be able to meet
these types of job requirements
Currently the dredging fleet in the world includes
about 40 large CSD-TSHD
To meet the increasing worldwide demand for high
pressure and large diameter discharge pipes
KIASMA has developed innovative HDPE piping
systems for the dredging industry able to resist to
pressures much higher than 10 bar
RAW MATERIALThe raw material used for the production of polyethylene pipes is classified in MRS (Minimum
Required Strength)
MRS is the strength value of the material against
the inner pressure along 50 years of work at 20deg
Verification was carried out subjecting the test pipe to 400000 cycles
Pipe is filled with water and a percentage of 30 of various types of inert (sand gravel
rock) The result is the following

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within
values does not damage the pipe

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

INTRODUCTIONTo reduce the cost per cubic meter of dredged material the ship builders in the last years
have turned their interests into building CSD (Cutter Suction Dredger) and TSHD (Trailing
Suction Hopper Dredgers) of large dimensions The evolution in the 60s saw installed
diesel power of 10000 kW to reach 13000 KW of power in the 70rsquos to then continue in the
80rsquos with 15600 KW of power to 20500 KW power in the 90rsquos growing to 22400 KW of
power in the 2000 to eventually reach a power of 27000 KW in the year 2015
The Safety Coefficient is determined according to the class of the raw material and the
conditions of the network Networks and all calculations are made according to this
coefficient
Safety Coefficient is C=125 for potable water distribution lines

HDPE PIPES FOR DREDGING
ABRASION RESISTANCE
In the near future dredging work will be
characterized by the production requirements (large
volumes at low cost) and by the geographical
peculiarity and the climatology of the sites to be
dredged (temperature climate storms waves
escape ways etc)
Only the large CSD amp TSHD will be able to meet
these types of job requirements
Currently the dredging fleet in the world includes
about 40 large CSD-TSHD
To meet the increasing worldwide demand for high
pressure and large diameter discharge pipes
KIASMA has developed innovative HDPE piping
systems for the dredging industry able to resist to
pressures much higher than 10 bar
RAW MATERIALThe raw material used for the production of polyethylene pipes is classified in MRS (Minimum
Required Strength)
MRS is the strength value of the material against
the inner pressure along 50 years of work at 20deg
Verification was carried out subjecting the test pipe to 400000 cycles
Pipe is filled with water and a percentage of 30 of various types of inert (sand gravel
rock) The result is the following

In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

FISH FARMING
HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

INTRODUCTIONTo reduce the cost per cubic meter of dredged material the ship builders in the last years
have turned their interests into building CSD (Cutter Suction Dredger) and TSHD (Trailing
Suction Hopper Dredgers) of large dimensions The evolution in the 60s saw installed
diesel power of 10000 kW to reach 13000 KW of power in the 70rsquos to then continue in the
80rsquos with 15600 KW of power to 20500 KW power in the 90rsquos growing to 22400 KW of
power in the 2000 to eventually reach a power of 27000 KW in the year 2015
The Safety Coefficient is determined according to the class of the raw material and the
conditions of the network Networks and all calculations are made according to this
coefficient
Safety Coefficient is C=125 for potable water distribution lines

HDPE PIPES FOR DREDGING
ABRASION RESISTANCE
In the near future dredging work will be
characterized by the production requirements (large
volumes at low cost) and by the geographical
peculiarity and the climatology of the sites to be
dredged (temperature climate storms waves
escape ways etc)
Only the large CSD amp TSHD will be able to meet
these types of job requirements
Currently the dredging fleet in the world includes
about 40 large CSD-TSHD
To meet the increasing worldwide demand for high
pressure and large diameter discharge pipes
KIASMA has developed innovative HDPE piping
systems for the dredging industry able to resist to
pressures much higher than 10 bar
RAW MATERIALThe raw material used for the production of polyethylene pipes is classified in MRS (Minimum
Required Strength)
MRS is the strength value of the material against
the inner pressure along 50 years of work at 20deg
Verification was carried out subjecting the test pipe to 400000 cycles
Pipe is filled with water and a percentage of 30 of various types of inert (sand gravel
rock) The result is the following

THERMAL EXTENSION(ELONGATION IN LENGTH DUE TO
TEMPERATURE VARIATION)
Elongation in length due to temperature
variation shall be taken into consideration
while laying HDPE (PE80 PE100) pipes In
the case that the temperature is increased
elongation will occur in length and
contraction will occur in case of decrease in
temperature
At 1 m of PE pipe for temperature variationfor each laquoKraquo number (1K=1degC) 018mm
elongation or contraction will occur
∆L = α x L x ∆T (∆L =m k mmmK983085983089 )
For instance in case of elongation or
contraction dependent to temperature in
length in a line built with PE piping pipe will
move from the turning point instead of the
fixed point Assume that for a 12 m pipe
normal operating temperature Tv= 20degC
maximum pressure T2=10degC According to
this variations in length dependent to
temperature are calculated as follows
Elongation dependent to temperature
increase
+ ∆L = Lx ∆T1xd= 1245x018=972mm
Calculation dependent to temperature
decrease
-∆L = Lx ∆T2xd= 1210x018=2160mm
Ls= Fixing distance (mm)
d = Pipe outer diameter (mm)k = factor 26 for HDPE
30 for PP
335 for PVC
If it is ∆L=972mm for a PE pipe with
diameter of Oslash63mm factor is 26 and clamp
distance is as follows
WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within
values does not damage the pipe

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

length in a line built with PE piping pipe will
move from the turning point instead of the
fixed point Assume that for a 12 m pipe
normal operating temperature Tv= 20degC
maximum pressure T2=10degC According to
this variations in length dependent to
temperature are calculated as follows

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

FISH FARMING
HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with
posts

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the

samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

FISH FARMING
HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with
posts

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies
Kiasma Srl RampD and commercial offices are available for more details

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within
values does not damage the pipe

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

Elongation in length due to temperature
variation shall be taken into consideration
while laying HDPE (PE80 PE100) pipes In
the case that the temperature is increased
elongation will occur in length and
contraction will occur in case of decrease in
temperature
At 1 m of PE pipe for temperature variationfor each laquoKraquo number (1K=1degC) 018mm
elongation or contraction will occur
∆L = α x L x ∆T (∆L =m k mmmK983085983089 )
For instance in case of elongation or
contraction dependent to temperature in
length in a line built with PE piping pipe will
move from the turning point instead of the
fixed point Assume that for a 12 m pipe
normal operating temperature Tv= 20degC
maximum pressure T2=10degC According to
this variations in length dependent to
temperature are calculated as follows
Elongation dependent to temperature

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example
table indicates the rate of increase of
new pressure value which is generated
by short term water hammer under 20degCtemperature for the varius safety factor
according to the nominal pressure
Pressure increase occurring within
values does not damage the pipe

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

while laying HDPE (PE80 PE100) pipes In
the case that the temperature is increased

WATER HAMMER
Water hammer occurs when valve or
pump is turned onoff For this following
formula is used theoretically
a propagation speed of pressure wave (msec)
V flow speed of the fluid (msec)
ρ fluid density (Kgmc)
In practice Ps value can be negative or positive
Positive taps can occur when turning off
the pump or while turning it on
Negative when turning off the pump or in
presence of a sudden change of
hydraulic property (ex sudden reduction
of flow speed)
Propagation speed of pressure wave is
calculated according to the following
formula
Short term elasticity module shall be used in this
formula(Er=800_1200Nmm2)
Short term pressure changes and water
hammer effect does not cause damage in
HDPE pipes The following example

samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

ABRASION OF HDPE DREDGING
PIPESHydrophilic HDPE which reduces
interaction between the transported
material and the pipe wall ensures high
abrasion resistance thus allowing the
pumping of abrasive materials like sands
gravels and mud
In the test case performed in Darmstadt
samples of sands and gravel (60
concentration) with thickness of 20 ndash 84
mm and water (40 concentration) were
used the dredged material tested by theUS Army Engineers varied (fine sand
pebbles and coarse sand)
In the presence of linear motion it has
been verified that most abrasion occurs in
the sliding surface of the HDPE pipe
through which most of the material passes
With turbulent motion abrasion occurs in a
completely different way

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

KFCcopy SYSTEM - Radial motion inside the HDPE pipes for
Dredging and Oil
INTRODUCTION
The conveying of the fluids under pressure in the discharge networks takes place in a
way defined as linear motion
When the fluid is flowing within the network the slope of the line energy decreases more
steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

THE KFC SYSTEM
The CFD analysis (Computational Fluid Dynamics) show the fluid-dynamic behavior of themixture inside the HDPE pipes applying and optimizing the KFC system
The application of the KFC system makes the mixture flowing inside the HDPE pipe
subjected to two motions
- Radial flow ( the mixture rotates along the circumference )
- Axial flow ( the mixture flows in the center of the pipe )
KFC copy SYSTEM FOR DREDGING and OIL
KIASMA983214
Group 12
The radial motion obtained by the KFC System forces the mixture to rotate along the entire
circumference of the pipe ( Mixture of medium and large sizes )
The axial motion transports in suspension the mixture consisting in small particles (sand -
clay - mud - gravel rock fine coral)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the

steeply due to the deposit of the transported material on the bottom of the pipe This is
happening both in steel and HDPE pipelines
As a consequence of the sedimentation the liquid section is reduced and the flow
dissipates most of the energy to carry the same scope
The linear motion is characterized by the formation of a bed that causes a localized
abrasion on the bottom of the pipe with a consequent problems of durability of thepipeline ( as per abrasion test conducted in accordance with EN 295-3 )
PRESSURE LOSS ANALYSIS
The pressure losses obtained by the KFC System are here compared to the pressure
losses
that occur in the steel pipe that for its own natural characteristic presents a much higher
roughness surface which causes a natural sedimentation of the transported mixture
The comparison was done with CFD and NX CAE software analysis according to the
principles of RANS (Reynolds Averaged Navier Stokes)
Setting an initial mixture speed of V = 4 m s assuming a percentage of mixture from
10 to 30 that in a steel pipe tends to deposit reducing the pipe surface there is an
increase of speed from 4 to 573 m s
With the speed increase also the pressure loss increases
Analyzing two pipes with the same diameters in a steel pipe with a linear mixture flow
and with an average sedimentation of 20 the pressure loss is 33 higher than the
same pipe diameter in HDPE with Kiasma KFC system
For ex
Pressure loss in steel pipe 6312 Pa = 0063 Bar ( pipe ID 900 mm )
Pressure loss in HDPE pipe- KFC System 4270 Pa = 0043 Bar ( pipe ID 900 mm )

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

FISH FARMING
HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies
Kiasma Srl RampD and commercial offices are available for more details

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

KFC copy SYSTEM FOR DREDGING and OIL
The KFC System developed by Kiasma inside the HDPE pipes determines a radial
motion to the mixture along the complete length of the pipe ( 118 m)
If the mixture is entirely composed by solids with a size up to 60-70 mm the KFC system
keeps active the radial motion inside pipes for 6 mt long pipes
If the mixture is made up of gravel - rocks - large size coral the KFC system is installed
inside the pipe also in a intermediate position along the length of the pipe therefore
keeping the radial flow along the entire length of 118 mt long pipe
KFC SYSTEM BENEFIT
With the KFC system the entire inner surface of
the pipe is subjected to a uniform abrasion with
evident benefit of the pipe life time
Furthermore is not longer necessary to use
labor force to rotate the pipe which usually
occurs during the dredging operations
Job References HDPE Pipes for dredging with KFC system
From year 2011 Kiasma Srl produces HDPE pipeline with the KFC System from diameter
OD 200 mm (10rdquo) till OD1200 mm ( 48rdquo) Kiasma also provides HDPE pipes with floating

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies
Kiasma Srl RampD and commercial offices are available for more details

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with
posts

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies
Kiasma Srl RampD and commercial offices are available for more details

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

RUBBER HOSES with KGP copy FLOATERS
Rubber hose with diameter from ID200mm to ID650mm with floater made of rigid freon-
free expanded polyurethane resin (55 Kgdmc) and PE outer sheath
The appropriate polyurethane-resin float guarantees pipe buoyancy as required by thedensity of the waste water and the weight of the system
Floating rubber hose ID650mm
PROPERTIES
Transport and on-site storage are optimized because floating sheaths are reduced in height
No installation costs normally required by traditional floating systems
Pipe buoyancy studied as a function of Archimedean buoyancy
Pipe flexibility remains unchanged
No repair or float replacement costs
Elimination of traditional float operating costs
All pipes produced according to the abrasion calculation

HDPE pipes are used as the most ideal product for such projects as
their specific density is lower than water and they have a flexible structure
resistant to impact not affected by salty water chemicals and sun
rays and have high strength against wave movements on the sea
In cage applications HDPE pipesbetween diameters of OD110mm
and OD500mm are mainly made
from PE100
Fish cages can be built in
diameters from 10m to 50m with
inner and outer floating pipe of
the same diameter and a third
safety pipe with small diameter
for qalking placed in the middle
Safety pipes are connected to the
inner floating pipe from top with

The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)

KPC copy SYSTEM

Group 33
The average values of viscosity and density of the oil can be different depending on the
site The pressure loss due to friction between the moving fluid and the wall of the pipelineconsumes energy
Our calculation sheets relating to the outflow of a mixture of oil and sand (in different
concentrations) let us estimate the energy loss (prevalence) along the discharge line
Our KPCcopy change of motion technology
(International Registered Utility) installed
inside the pipeline allows to obtain the
following benefits
bull Lower power consumption (less pressure
drop)bull Less abrasion of the inner walls of the
pipes (pseudo-homogeneous motion in
which the particles flow in suspension on
the center of the pipe)
bull Increased pressure with greater
production on the same energy
upstream
bull Longer length of the transportation line
Different pipe diameters require different numbers of inverters capable of changing the
motion
Off-Shore and In-Shore installations
Easy to install both off-shore and in-shore KPCcopy system reduces pipeline oil passage wear
by 42 with obvious economic benefits for oil companies
Kiasma Srl RampD and commercial offices are available for more details

The conveyance of fluids in pressurized discharge networks takes place via a passage
defined as linear motion As fluid flows through the network the energy line slope dropsmore sharply as transported material is deposited on the bottom of the duct resulting in a
reduced liquid section caused by this sedimentation The flow must therefore dissipate more
energy to give the same final result
Linear motion is characterized by the formation of a bed that causes abrasion on the bottom
of the pipe with problems of durability of the network (this fact is proved by the abrasion test
conducted in accordance with EN 295-3 at the Hydraulics Laboratory of the Faculty of the
US Army Eng Waterways Experiment Station (USA)
