Notes:
Note 1 At Gas LHV 49620kJ/kg
Note 2 At ISO 3046-1 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Flow tolerance 5% and temperature tolerance 10°C in gas mode operation. Flow tolerance 8% and temperature tolerance 15°C in diesel mode operation.
Note 3 At 100% output and nominal speed. The figures are valid for ambient conditions according to ISO 3046/1, except for LT-water temperature, which is corresponding to charge air receiver temperature 45ºC in gas operation. With engine driven water and lubricating oil pumps. Tolerance for cooling water heat 10%, tolerance for radiation heat 30%. Fouling factors and a margin to be taken into account when dimensioning heat exchangers.
Note 4 At ambient conditions according to ISO 3046/1, fuel net calorific value 42700 kJ/kg, with engine driven pumps (two cooling water + one lubricating oil pumps). Tolerance 5%.
Note 5 Fuel gas pressure given at LHV ≥ 36MJ/m³N. Required fuel gas pressure depends on fuel gas LHV and need to be increased for lower LHV's. Pressure drop in external fuel gas system to be considered. See chapter Fuel system for further information.
ME = Engine driving propeller, variable speed
AE = Auxiliary engine driving generator
DE = Diesel-Electric engine driving generator
