Notes:
Note 1 At ISO 3046-1 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Tolerance 5%.
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 15°C.
Note 3 At ISO3046-1 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 ac- count when dimensioning heat exchangers.
Note 4 According to ISO 3046/1, lower calorific value 42 700 kJ/kg, without engine driven pumps. Tolerance 5%. Load according to propeller law for mechanical propulsion engines (ME).
ME = Engine driving propeller, variable speed
DE = Engine driving generator
