Notes:
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Flow tolerance 5%. Note 1
At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C). Flow tolerance 5% and temperature tolerance
10°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 20%. Fouling factors and a margin to be taken into account when dimensioning heat
exchangers. In arctic option charge air coolers in LT circuit. Note 3
At ambient conditions according to ISO 15550. Lower calorific value 42 700 kJ/kg. With engine driven pumps (two cooling
water + one lubricating oil pump). Tolerance 5%. Note 4
ME = Engine driving propeller, variable speed
AE = Auxiliary engine driving generator
DE = Diesel-Electric engine driving generator
