Ratings
Ratings are based on ISO 8665 conditions of 100 kPa (29.612 in Hg) and 25°C (77°F) and 30% relative humidity. Rated power represents the net power available at crankshaft.
Fuel consumption has a tolerance of +7% and is based on fuel of 35° API gravity at 16°C (60°F) having an LHV of 42,780 KJ/KG (18,390 BTU/lb) when used at 29°C (85°F) and weighing 838.9 g/liter (7.001 lb/US gal) with LTA when available.
L Light Duty Commercial
For commercial vessels or craft with high demands on speed and acceleration, planing or semi-planing hulls in cyclical operation. Typical boats: Fast patrol, rescue, police, light fishing, fast passenger and taxi boats etc. Full power could be utilized maximum 2 h per 12 h operation period. Between full load periods, engine speed should be reduced at least 10 % from the obtained full load engine speed.
M Medium Duty Commercial
For commercial vessels with semiplaning or displacement hulls in cyclical operation. Typical boats: Most patrol and pilot boats, coastal fishing boats in cyclical operation, light trawlers, passenger boats and coastal freighters with shorter trips. Full power could be utilized max 4 h per 12 h operation period. Between full load operation periods, engine speed should be reduced at least 10 % from the obtained full load engine speed.
C Continuous Duty Commercial
For vessels operating at rated load and rated speed up to 100% of the time without interruption or load cycling (80% to 100% load factor). This a SPE Special Purpose Engine option, please contact factory for information.
Generator Drive Engines
Engines with this rating are available for an unlimited number of hours per year in variable load applications. Variable load is not to exceed 70 percentage average of the rated power during any operating period of 250 hours. Total operating time at 100 persent prime power shall not exceed 500 hours per year.
