Versatile Pacific Shipyards Inc. delivered the Arctic Class 4 icebreaker Henry Larsen to the

Canadian Coast Guard. Powered by an AC marine propulsion system that includes Wartsila

Vasa diesel engines and General Electric Canada synchronous generators, the Henry Larsen can reach speeds of 13.5 knots in the open sea.

Dutch Yard To Build

Six Multipurpose Ships

The Dutch shipyard Van der

Giessen-de Noord was recently awarded a contract by Van Nievelt,

Goudriaan to build six multipur- pose carriers. The 6,000-dwt ships will be built to carry containers, oil products and bulk cargo.

The Detroit Diesel-powered catamaran ferry Jelang K was recently delivered to the U.S

Army for use at a missile test range in the Marshall Islands.

The Northern Vancouver yard of

Versatile Pacific Shipyards, Inc. (VPSI) has delivered the Type 1200

Arctic Class 4 icebreaker Henry

Larsen to the Canadian Coast

Guard. She is now in operation pro- viding large vessel escort service in the Gulf of St. Lawrence during the winter months and in the Eastern

Arctic in the summer months.

Commenting on the delivery of the Henry Larsen, David Alsop, president and chief executive officer of VPSI, said the ship performed well during her sea trials and "we are confident the Government of

Canada and the Coast Guard are taking delivery of a first class vessel that will meet all expectations."

As reported in the September is- sue of MARITIME REPORTER, the Henry Larsen is 327.5 feet long, has a beam of 64.6 feet and displace- ment of 8,290 tons at a draft of 23.7 feet. She is powered by an AC marine propulsion plant consisting of three main generator sets, cyclo- converters and synchronous motors.

Three Wartsila Vasa type 16V32 diesel engines each rated at 5,250 kw at 720 rpm, drive General Electric

Canada ATI synchronous genera- tors with brushless exciters. Each generator is rated at 5,000 kw, 4,160 v, 6,250 kva at 720 rpm. Cullen Can- ada Inc., Vancouver, B.C., Canada, supplied the main propulsion gener- ator sets.

Auxiliary power is supplied by a 625-kw Stromberg HSPTL 10/653 generator driven by a Wartsila Vasa 6R22 rated at 960 kw at 1,200 rpm.

She is also fitted with a Caterpillar emergency generator set.

The Henry Larsen can accommo- date a crew of 72, has a cruising range of about 15,000 nautical miles, a cruising speed of about 13.5 knots and a total shaft horsepower of 12,000 kw through two Lips propel- lers.

One special feature of the Henry

Larsen is her advanced Asea Brown

Boveri (ABB) Integrated Automa- tion System. The system provides true integration of control and in- strumentation functions, integrat- ing prime mover control with elec- tronic governors, start permissives and safety systems; alarm and mon- itoring; fan, valve, pump and com- pressor control; power management; fuel consumption calculation and presentation; and tank gauging.

Completed under a C$96.8-mil- lion contract as one of several new- buildings and modernizations planned or underway in the Canadi- an Coast Guard's Capital Projects, the Henry Larsen is one of Canada's largest icebreakers. To enhance her icebreaking capabilities and in- crease her maneuverability, she is fitted with a Wartsila Air Bubbling

System, which reduces friction be- tween the hull and the surrounding ice. Additionally, she is fitted with a heeling/stabilizing system by Inter- ing of Germany through Jastram

Canada.

The icebreaker is named in honor

Nichols Brothers Boat Builders,

Inc., Whidbey Island, Wash., re- cently christened the second of two catamaran passenger ferries it has built for the U.S. Army for use in the Marshall Islands.

Built under a $1.8-million con- tract, the 72-foot FB-817 Jelang K will join the FB-816 Jera at the

Army's missile range in the Mar- shall Islands. The 31-knot Jelang K will be barged to the Marshall Is- lands for use as a ferryboat for tech- nical personnel working at the U.S.

Army Kwajalein Atoll test range.

With a beam of 28 feet 6 inches and a draft of 5 feet 11 inches, the vessel will carry 1,100 gallons of fuel oil, 250 gallons of water, and 232 passengers at full load. She is pow- ered by a pair of Detroit Diesel 16V92 TA 960-hp main engines sup- plied by Pacific Diesel Power of

Portland, Ore. The engines are cou- pled to ZF model BW250 reduction gears with a ratio of 2.03:1, and 37- inch by 36.5-inch, five-bladed bro- nze propellers from Osborne Propel- lers.

The two 50-kw Northern Lights auxiliary generators are driven by

John Deere 4276 engines. Systems

Engineering provided propulsion controls and Hough Marine, the steering system. The vessel's air conditioning was engineered by Cel- cius Marine, Inc., with duct work by

Puget Sound Refrigeration.

The Jelang K is based on a design by International Catamaran De- signs Pty. Ltd., of Australia. Nichols

Brothers Boat Builders and Glad- ding-Hearn Shipbuilders, Somerset,

Mass., are the only shipbuilders in the U.S. licensed to build this type of catamaran.

Electronics include a Data Ma- rine LX201 fathometer, Standard

Communications VHF radio, Furu- no FCR 1411/6 radar, Furuno 8030D radar, and Data Marine

LX50 speed log. The electronics package was provided by Northern

Marine Electronics of Seattle.

Current contracts at the Whidbey

Island, Wash., yard include an order for a 35-knot advanced technology "wave piercer" catamaran from Cal- ifornia Cruisin', as well as an order for six passenger catamarans to be delivered to Puerto Rico over the next two years.
