B RATING – Displacement hull vessels such as mid-water trawlers, purse seiners,crew and supply boats, ferries, and towboats where locks, sandbars, and curvesdictate frequent slowing, and engine load and speed are constant with somecycling.

A RATING – For heavy-duty service in ocean-going displacement hulls such asfreighters, tugboats, bottom drag trawlers, and deep river towboats when theengine is operated at rated load and speed up to 100% of the time withoutinterruption or load cycling.

PERFORMANCE DATA*


* Represents performance along a typical fixed pitch propeller curve.** Power rated in accordance with NMMA procedure as crankshaft power. For units equipped with Caterpillar-supplied marine gears,

reduce crankshaft power by 3% for propeller shaft power.

Fuel use reflects SAE standards. Fuel use reflecting ISO standards is typically 2-3% less. Consult your Caterpillar representative for details.

E – Planing hull vessels such as pleasure craft,harbor patrol, harbor master, and some .fishing and pilot boats.

D – Planing hull vessels such as off-shore patrolboats, customs, police, and some fire and fishing boats. Also used for bow and sternthrusters.

C – Planing hull vessels such as ferries, fishing boats moving at higher speeds out and back(i.e. lobster, crayfish, and tuna), off-shore service boats, and also displacement hull .yachts and short trip coastal freighters whereengine load and speed are cyclical.

MARINE CERTIFICATION

Ratings are marine classification society approvedby ABS, BV, CCS, DnV, GL, KR, LRS, NKK, RINA, andRS. These societies have also granted 3600 factoryline production approval which eliminatesrequirement for society surveyor witness test.

FUEL CAPABILITY

The 3600 family of engines is developed foroperation on fuel with viscosity and contaminatesup to CIMAC Class K55 (700 cSt @ 50° C). Thepower ratings listed apply to distillate fuels,including most grades of marine diesel oil. Heavyfuel ratings are 9% less than distillate fuel andrequire factory approval.

RATING CONDITIONS AND DEFINITIONS

For high speed commercial application.

Approximate load profile: 85% of operating hoursat rated power, 15% of hours at <50% rated power.TBO approximately 20-25,000 hours. INT: Poweravailable for use during acceleration and othertransient conditions. CONT: Power available forcontinuous service. Propeller demand curves areshown through 100% power. The propulsion system design should consider heavy ship condition, sea state, hull fouling, and propulsionsystem power losses for proper match betweenengine and prop/jet.

Ratings are based on SAE J1349 standard conditions of 100 kPa (29.61 in Hg) and 25° C (77° F). These ratings also apply at ISO3046/1,ISO8665, DIN6271, and BS5514 standard referenceconditions. Ratings also meet classification societymaximum temperature requirements of 45° C (113° F) temperature to turbo and 32° C (90° F) seawater temperature without derate.

Fuel Consumption is based on ISO3046/1 with +5%tolerance at rated power for fuel having an LHV of42,780 kJ/kg (18,390 Btu/lb) and weighing 838.9g/liter (7.001 lbs/U.S. gal). Includes engine-mount-ed fresh water and lube oil pumps. SFOC withoutpumps 2% less.
