Resilient Mounting


P.01.700 1 / 1

PROJECT GUIDE

The number and position of the resilient mounts depend on the dynamic characteristics of theplant. Therefore, the final specification of the mounts shall be decided based on theinformation from the shipyard case by case.

Generating-set mounted on the resilient mounts usually has some relative motions to the hullstructure. Any rigid fixing between generator set and hull structure causes damages ofgenerator set or hull. Therefore, all connections, for example, pipes, gratings, ladders, electricwires, etc., should be flexible enough to absorb the relative movements.

The foundation for Common Base Frame mounting should be rigid enough to support the loadfrom Generator Set. Steel Shim Plates with a thickness of minimum 25mm between resilientmounts and foundation are required to adjust leveling of each mount(Method 1). Additionalshim plate(min. thickness 10mm) can be used for adjustments(Method 2) as shown below. Itis also recommended to check the crankshaft deflection before starting up the plant to securethe correct adjustments of the shim plate and leveling of the generator set.

A HiMSEN Generating-set consists ofDiesel engine and Generator mounted onCommon Base Frame. The Common BaseFrame is installed on resilient mounts onthe foundation in the ship.

A resilient mounting of the generating-set ismade with a number of rubber elements toisolate vibrations between generator setand hull structure. These rubber elementsare bolted to brackets of the Common Bedas shown on right figure.

Remark) H1 is overhaul height of the cylinder unit passing through the turbocharger.

Measurement of NOx Emission

IMO Tier II NOx Limit

H25/33 Measurements(Typical)

HiMSEN H25/33 is designed forenvironment-friendly engine and satisfiesIMO NOx emission limit with low fuelconsumption and nearly smokelessoperation even at idle load.

Typical exhaust compositions in volumeratio at full load are as follows: The amount of NOx Emission depends on

the engine operating condition, typically highcombustion temperature and specific fuel oilconsumption. A new engine shall beoptimized to meet the customer's specificrequirements. However, an engine in servicealso can be optimized further regarding NOxemission, if needed. In this case, trade offwith SFOC might be considered as follows:

Residue is little in amount but ecologicallycritical. Therefore, a careful attention isrequired for the treatment of fuel oil andengine operating conditions.

If there is no special requirements fromcustomer regarding the exhaust gasemission, HiMSEN Genset shall bedelivered with optimized performanceconditions fulfilling the IMO limit value ofNOx emission.

Therefore, it is strongly requested to contactthe engine maker if there is any furtherrequirements regarding exhaust gas emissionor special operating conditions.

Correction for ambient condition

Specific Fuel Oil Consumption(SFOC) is refered to the ISO 3046/1 reference condition normally.

However, for the condition other than ISO 3046/1 reference condition,the SFOC at MCR can be estimated according to the below mentioned formula.

SFOCamb = SFOCISO * dSFOC dSFOC = [100 + (Tamb-25)*0.05 - (Pamb-1000)*0.007 + (Tcw-25)*0.07 - (LCV-42700)/427] / 100

SFOCamb : Specific Fuel Oil Consumption at actual operating condition [g/kWh]SFOCISO : Specific Fuel Oil Consumption at ISO 3046/1 reference condition [g/kWh]dSFOC : Deviation of the SFOCTamb : Ambient air temperature at actual operating condition []Pamb : Ambient air pressure at actual operating condition [mbar]Tcw : Cooling water temperature before Charge Air Cooler(CAC) at actual operating condition []LCV : Lower Calorific Value of the fuel oil [kJ/kg]

Example,Ambient air temperature(Tamb) : 30 []Ambient air pressure(Pamb) : 990 [mbar]Cooling water temperature(Tcw) : 30 []Lower Calorific Value(LCV) : 42700 [kJ/kg]SFOCISO : 184 [g/kWh]

then, dSFOC = 1.0067 and the SFOC at site condtion will be increased to 185.2[g/kWh].

If engine driven pumps are attached, the SFOC at MCR will increase approximately as follows:

Correction for exhaust gas temperature after turbine.

Exhaust gas temperature after turbine is refered to ISO 3046/1 standard condition normally.

However, for the condition other than ISO 3046/1 standard condition,the exhaust gas temperature after turbine could be estimated according to the below mentioned formula.

Taturbexh = TaturbISO + dTaturb dTaturb = (Tamb-25)*1.5 + (Tcw-25)*0.7

Taturbexh : Exhaust gas temperature after turbine at actual operating condition []TaturbISO : Exhaust gas temperature after turbine at ISO 3046/1 standard condition []dTaturb : Deviation of the exhaust gas temperature after turbine []Tamb : Ambient air temperature at actual operating condition []Tcw : Cooling water temperature before Charge Air Cooler(CAC) at actual operating condition []

Example,Ambient air temperature(Tamb) : 35 []Cooling water temperature(Tcw) : 35 []TaturbISO : 290 [] at 720[rpm], MCR

then, dTaturb = 22 [] and the Taturbexh at actual operating condition will be increased to 312 [].

Engine output power at MCR shall be reduced depending on the ambient air temperature,cooling water temperature and site altitute.

Example

Cooling water temperature before charge air cooler : 36[]Ambient air temperature : 30[]Site altitute : 1000[m]

From the power derating diagram, the power derating factor at actual operating condition is 0.97.Therefore the engine output power at actual operating condition should be derated to the 97%of the standard engine power.

Remark : 1) No overload is permissible expect for 10% over load during official factory test.2) The alternator outputs are calculated for an efficiency of 95% and a power factor of 0.8 lagging.3) Power adjusting upto -5% deratingis generally accepted. However, other power adjusting must be consulted to engine builder.

Measurement of NOx Emission

IMO Tier II NOx Limit

H25/33 Measurements(Typical)

HiMSEN H25/33 is designed forenvironment-friendly engine and satisfiesIMO NOx emission limit with low fuelconsumption and nearly smokelessoperation even at idle load.

Typical exhaust compositions in volumeratio at full load are as follows: The amount of NOx Emission depends on

the engine operating condition, typically highcombustion temperature and specific fuel oilconsumption. A new engine shall beoptimized to meet the customer's specificrequirements. However, an engine in servicealso can be optimized further regarding NOxemission, if needed. In this case, trade offwith SFOC might be considered as follows:

Residue is little in amount but ecologicallycritical. Therefore, a careful attention isrequired for the treatment of fuel oil andengine operating conditions.

If there is no special requirements fromcustomer regarding the exhaust gasemission, HiMSEN Genset shall bedelivered with optimized performanceconditions fulfilling the IMO limit value ofNOx emission.

Therefore, it is strongly requested to contactthe engine maker if there is any furtherrequirements regarding exhaust gas emissionor special operating conditions.

Correction for ambient condition

Specific Fuel Oil Consumption(SFOC) is refered to the ISO 3046/1 reference condition normally.

However, for the condition other than ISO 3046/1 reference condition,the SFOC at MCR can be estimated according to the below mentioned formula.

SFOCamb = SFOCISO * dSFOC dSFOC = [100 + (Tamb-25)*0.05 - (Pamb-1000)*0.007 + (Tcw-25)*0.07 - (LCV-42700)/427] / 100

SFOCamb : Specific Fuel Oil Consumption at actual operating condition [g/kWh]SFOCISO : Specific Fuel Oil Consumption at ISO 3046/1 reference condition [g/kWh]dSFOC : Deviation of the SFOCTamb : Ambient air temperature at actual operating condition []Pamb : Ambient air pressure at actual operating condition [mbar]Tcw : Cooling water temperature before Charge Air Cooler(CAC) at actual operating condition []LCV : Lower Calorific Value of the fuel oil [kJ/kg]

Example,Ambient air temperature(Tamb) : 30 []Ambient air pressure(Pamb) : 990 [mbar]Cooling water temperature(Tcw) : 30 []Lower Calorific Value(LCV) : 42700 [kJ/kg]SFOCISO : 184 [g/kWh]

then, dSFOC = 1.0067 and the SFOC at site condtion will be increased to 185.2[g/kWh].

Correction for engine driven pump

If engine driven pumps are attached, the SFOC at MCR will increase approximately as follows:
