Gladding-Hearn Delivers New DDEC-

Equipped Research Vessel

The research vessel Gulf Challenger.

Gladding-Hearn Shipbuilding, The Duclos

Corp., delivered a new research vessel, the Gulf

Challenger, powered by DDEC-controlled en- gines, to the University of New Hampshire.

The vessel's designer, Roger Long of Roger

Long Marine Architecture, South Portland, Me., said that the new 50-foot, all-aluminum vessel was designed to operate year-round anywhere on the Gulf of Maine and coastal rivers.

The aluminum hull was strengthened for op- erating in icy waters. The university also opted for the strict Subchapter T(s) U.S. Coast Guard (USCG) certification. This allows the vessel to carry passengers for hire and ensures its addi- tional safety features are properly maintained annually.

The vessel's engine performance is controlled by Detroit Diesel's DDEC fuel-injection system because, like other research boats, it frequently runs at low speeds or idles for long periods. In addition to constantly reporting engine and trans- mission performance, the electronic operating system allows the engines to idle longer at slow speeds and run cleaner.

Powered by twin Detroit Diesel 8V-92 turbo- charged engines, each rated at 600 bhp, the vessel's 24 knot-plus top speed ensures faster trips within 100 miles of the New England coast. "The DDEC system combined with the vessel's shallow-V planing hull, will improve the engine's overall fuel economy, but especially at low speeds,"

Mr. Long said.

A Northern Lights generator, inside a sound- proofed enslosure, provides AC power.

Alcan Crewboat, M/V "Wachwas,"

Undergoes Extensive Repower And

Refit With Cat Engine (Credit: Alan Haig-Brown)

Alcan Smelters and Chemicals Ltd. has car- ried out an extensive repowering project on its high speed passenger ferry MTV Wachwas.

Peter S. Hatfield Ltd., Naval Architects and

Marine Consultants of Vancouver, B.C., were entrusted with the repower design details and engineering, and following tender evaluation,

Allied Shipbuilders Ltd., of North Vancouver,

B.C. was contracted to carry out the engine refit project.

The repower option study included three dif- ferent makes of North American engines, with the final choice being Caterpillar Model 3512

DITA, developing 1,445 bhp at 1,800 rpm (B rating). The two 3512s, including ancillary equip- ment, were supplied by Finning Power Systems of Vancouver, B.C.

Engineering design and subsequent shipyard work included new engine beds, new exhaust, cooling water and fuel systems piping. New controls, custom engine modifications such as shallow industrial oil pump with scavenge pump, remote mounted jacket water expansion tanks, heat exchangers and air separator units, were addressed and successfully undertaken.

The triple screw 120-foot by 24-foot aluminum

Gulf Coast crew boat was built in 1981 by the

Swiftship Yard in Louisiana for the Canadian

Marine Drilling Co. for operations in the Beau- fort Sea.
