Cummins-Powered Crewboat Being Built At Matsumo Yard For Esso Resource Canada

An unusual crewboat for ferrying oil field workers across the Mackenzie River in Canada's Northwest Territories is nearing completion at Matsumoto Shipyard, Ltd., on the Dollarton waterfront of North Vancouver, British Columbia, for Esso Resources Canada Ltd. of Calgary, Alberta.

The 39-foot aluminum boat, named the R.W. MacKinnon, is unusual in several respects: power is provided by a pair of Cummins 6BTA5.9-M diesel engines, propulsion is furnished by Parker waterjet units manufactured in England, and equipment includes a bow ramp for transferring passengers directly to and from the river's sandy shores.

Designed for shallow water use, the 13-foot-beam 20,000-pound (fully outfitted) personnel carrier— capable of carrying 16 passengers— will be nosed onto the beach for rapidly accommodating drilling, construction and field operation personnel being shuttled between the mainland and artificial and natural islands where the wells are located.

The Cummins new 6BTA5.9-M diesel engine is a turbocharged, aftercooled engine of an in-line, sixcylinder configuration that weighs only 1,250 pounds with marine gear.

The engine develops 220 horsepower at 2,500 rpm. Minimal weight and high horsepower were needed in this type of boat to achieve the 20 knots specified for performance.

Esso's new crewboat R.W. MacKinnon will be one of the last boats emerging from the yard. At the age of 70, Isami (Sam) Matsumoto is retiring after building boats at the same location for four decades For free literature giving full details on Cummins engines, Circle 41 on Reader Service Card
