ISO CertificationFactory-designed systems built at CaterpillarISO9001:2000 certified facilities
A Rating (Unrestricted Continuous)Typical applications: For vessels operating atrated load and rated speed up to 100% of the timewithout interruption or load cycling (80% to 100%load factor). Typical applications could include butare not limited to vessels such as freighters,tugboats, bottom drag trawlers, or deep rivertugboats. Typical operation ranges from 5000 to8000 hours per year.
B Rating (Heavy Duty)Typical applications: For vessels operating atrated load and rated speed up to 80% of the time, or10 hours out of 12, with some load cycling (40% to80% load factor). Typical applications could includebut are not limited to vessels such as mid-watertrawlers, purse seiner, crew and supply boats,ferries, or towboats. Typical operation ranges from3000 to 5000 hours per year.
C Rating (Maximum Continuous)Typical applications: For vessels operating atrated load and rated speed up to 50% of the time,or 6 hours out of 12, with cyclical load and speed(20% to 80% load factor). Typical applicationscould include but are not limited to vessels such asferries, harbor tugs, fishing boats, offshore serviceboats, displacement hull yachts, or short tripcoastal freighters. Typical operation ranges from2000 to 4000 hours per year.
D Rating (Intermittent Duty)Typical applications: For vessels operating atrated load and rated speed up to 16% of the time,or 2 hours out of 12, (up to 50% load factor).Typical applications could include but are notlimited to vessels such as offshore patrol boats,customs boats, police boats, some fishing boats,fireboats, or harbor tugs. Typical operation rangesfrom 1000 to 3000 hours per year.
Power at declared engine speed is in accordancewith ISO3046-1:2002E. Caterpillar maintainsISO9001:1994/QS-9000 approved engine testfacilities to assure accurate calibration of testequipment. Electronically controlled engines are setat the factory at the advertised power corrected tostandard ambient conditions. The published fuelconsumption rates are in accordance withISO3046-1:2002E.
Fuel rates are based on fuel oil of 125° API [16°C(60°F)] gravity having an LHV of 42 780 kJ/kg(18,390 Btu/lb) when used at 29°C (85°F) andweighing 838.9 g/L (7.001 lb/U.S. gal). Additionalratings may be available for specific customerrequirements. Consult your Caterpillarrepresentative for additional information.
The International System of Units (SI) is used in this publication.
Performance data is calculated in accordance with tolerances and conditions stated in this specification sheet and is only intended for purposes ofcomparison with other manufacturers’ engines. Actual engine performance may vary according to the particular application of the engine and operatingconditions beyond Caterpillar’s control.
Power produced at the flywheel will be within standard tolerances up to 49°C (120°F) combustion air temperature measured at the air cleaner inlet, and fueltemperature up to 52°C (125°F) measured at the fuel filter base. Power rated in accordance with NMMA procedure as crankshaft power. Reduce crankshaftpower by 3% for propeller shaft power.
