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

Safety coefficient is expressed as total operation coefficient according to ISO 12162 and

has numerous functions Primarily safety shall be ensured in case of accuracy of pipe

calculations (measurements) and increase of nominal pressure inside the pipe

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

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

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

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

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

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

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

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

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

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

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)

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

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)

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

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)

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

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

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

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)

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

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)

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)

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

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)

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 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)

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

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 )

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

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

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

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

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)

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

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

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

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)

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

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

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)

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

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

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

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

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)

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)
