Cummins KT-2300-Marine Diesel Makes North American Debut
The M/V Ocean Marauder, recently launched in the waters off Vancouver, British Columbia, Canada, is the first North American fishing vessel powered by a Cummins KT-2300-M diesel engine.
An 86-foot seiner built by John Manly Shipyards of Vancouver for Ocean Fisheries and Wishing Star Fisheries, also of Vancouver, the Ocean Marauder cruises along the Pacific Northwest Coast, fishing for salmon and herring.
The fish holds are styrofoam lined and fiberglass covered to insulate and protect the catch, and a built-in bubbling system circulates slush ice and brine uniformly through the tanks. The Ocean Marauder provides comfortable living quarters for Capt. John Lenic and his five-man crew. Fuel and freshwater tanks have capacities of 3,400 and 1,730 gallons, respectively. The sleek steelhulled vessel's 13-foot molded depth and 24- foot beam accommodates four fish holds, with a total volume of 5,600 cubic feet and catch capacity of 160 tons.
On-deck and bridge equipment includes a 48-inch by 17-inch two-motor purse main winch, manufactured by Hytac Ltd., a Pilkington Blacksmith's net drum, and various boom and line winches by Gearmatic Co. Electronic components onboard, including radar, radio and depth finder units, are manufactured by Wagner.
The Ocean Marauder's compact KT-2300-M V-12 turbocharged diesel, with a continuous duty rating of 700 bhp (522 kw) at 1,800 rpm, drives a three-blade 64-inch by 66-inch Western stainless-steel propeller in a Korttype nozzle. Power is provided through a Twin Disc MG-527, 5.17:1 gear. The low surface-area-to-volume ratio due to large cylinder displacement along with improved manifolding, short injection period and improved breathing, all make the KT-2300-M one of the most fuel-efficient marine diesels available in its size and horsepower range. For ease of maintenance and serviceability, the Cummins K engine also includes internal fuel and oil lines, and individual cylinder heads.
Cummins Diesel Sales of B.C. Ltd., North Burnaby, B.C., supplied the KT-2300-M engine and Twin Disc marine gear, as well as the Cummins NT-495 marine auxiliary engine and a Cummins V-555-M rated at 185 hp continuous duty for the seine skiff. The NT-495 operates the vessel's generator, hydraulic system and bow thrusters.
