ABB Set To Get Power Supply System Job For Carnival's 'Imagination'

The final details for a contract between Asea Brown Boveri (ABB) Marine, of Finland, and Carnival Cruise Line (CCL) for supplying the comprehensive power supply system for CCL's latest cruise ship, the Imagination, are close to being finalized.

The 70,000-gt Imagination is the fifth CCL newbuilding to be ordered from Finland's Kvaerner Masa- Yards and its predecessor, Wartsila Marine. When delivered in 1995, the $330 million Imagination will have a station-type power plant to provide electricity for propulsion machinery and other shipboard requirements.

ABB Marine, an electrical drive specialist, will provide its AC/ AC Cyclo system for the project.

Although the hardware is similar to the other ships built in the class, certain design refinements will be incorporated into the imagination by the company. Each ABB installation for the CCL newbuildings to date have been comprised of two 14- mw Cyclo propulsion drives, 6.6-kv switchboards, four 10.3-mv and two 6.8-mv generators, plus six 1.5-mw thruster motors.

Each of the two electric AC synchronous motors is connected directly to one of the propeller shafts, providing smooth shaft torque throughout the entire speed range.

This minimizes vibration, even at very low speeds.

The ship's propulsion plant consists of 6 prime movers of the Sulzer ZA40S medium-speed type, with 4 engines being 12-cylinder and the other two 8-cylinder units. Engines for the project are being manufactured at the Turku engine factory of licensee Wartsila Diesel.
