At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C). Flow tolerance 5% and temperature tolerance
20°C.
Note
2
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Tolerance for cooling water heat
10%, tolerance for radiation heat 30%. Fouling factors and a margin to be taken into account when dimensioning heat ex-
changers.
Note
3
According to ISO 15550, lower calorific value 42700 kJ/kg, with engine driven pumps (two cooling water + one lubricating
oil pumps). Tolerance 5%. The fuel consumption at 85 % load is guaranteed and the values at other loads are given for in-
dication only. Consumption values in DE constant speed are valid for D2/E2 IMO cycles. If Wartsila NOR is installed SFOC
consumption values may vary. Please contact Wärtsilä to have further informations.
Note
4
At manual starting the consumption may be 2...3 times lower.Note

ME = Engine driving propeller, variable or constant speed
DE = Diesel-Electric engine driving generator at constant speed
