efficient gas turbines which propel more than 375 vessels, from plea- sure yachts and fast ferries, to frigates and destroyers for the U.S.

Navy (and 23 foreign navies). The

LM series ranges in power from 6,000 to 50,000 hp. Full opera- tional availability in the world's

LM-powered fleet averages more than 99 percent. In marine appli- cations, LM gas turbines are avail- able as base-mounted models or as a complete, packaged, shock- mounted propulsion system ready for shipboard use. Recent fast ferry programs which feature LM gas turbines are the Stena's HSS-class

Explorer, the Aquastrada-class

Guizzo, SEAJET 250 and Far East

Hydrofoil's Foilcat. The high-speed yacht Destriero, powered by three

LM1600s, set the transatlantic crossing record in 1992.

Additionally, GE maintains a facility in Lynn, Mass., dedicated to the design, manufacture and testing of propulsion gears for the

U.S. Navy and commercial ships.

GE provides gearing for LNG tankers, including two being built by Fincantieri in Italy, slated for delivery in 1996 and 1997. GE gears are also used on the U.S.

Navy's Arleigh Burke DDG-51 destroyers, and will be used on

NASSCO-built Sealift vessels for the U.S. Navy. — GE Industrial Systems (Salem, Va.) manufactures electri- cal adjustable speed power con- verter equipment and associated motors, process controls and tur- bine controls. GE's adjustable speed drives and motors have been applied to main propulsion, thrusters, cargo pumps and azimuth drives, and range from 200 to 25,000 hp, for both DC and

AC power propulsion systems. In addition, GE's Mark V turbine con- trollers are available for both steam and gas turbines. GE

Industrial Systems' drives and propulsion motors can be found on dinner boat Creole Queen (DC thrusters), Canadian Coast

Guard's Class-1200 icebreakers (AC propulsion), MSC fast sealift vessels (Mark V gas turbine con- trols), as well as on a variety of other workboats and oceanograph- ic research vessels. — GE Power Systems (Schenectady, N.Y.) provides sup- port for other activities which are crucial to optimizing customers' marine power systems. Services include marine systems applica- tion engineering and design using computer-aided engineering and design for electric propulsion sys- tems and GE's advanced gas tur- bine combined-cycle propulsion systems. GE also offers system optimization, equipment selection and system layout. — GE Marine Systems (Hampton, Va.) offers two principal products: marine automation sys- tems and marine power distribu- tion systems. These products pro- vide round-the-clock automatic monitoring and control over a ship's machinery plant that is tai- lored to meet owner and classifica- tion society requirements. GE

Marine Systems also provides pro- ject management, system engi- neering, integration engineering and installation/start-up engineer- ing services to ensure GE systems meet all customer requirements.

GE marine automation systems are PLC-based systems which pro- vide for fully automatic or remote manual control over a ship's main propulsion and auxiliary machin- ery. This type of system can accom- modate a wide variety of inputs from sensors built into the ship's systems or embedded in machin- ery. GE works with shipbuilders and equipment suppliers to define what machinery is to be monitored and controlled, from what locations and under what modes of opera- tion.

GE power distribution systems are designed and built to connect the ship's electrical generating capacity with the ship's connected electrical loads. Full metering and switching relaying are provided with these systems. GE Marine

Systems has systems on container liners, breakbulk cargo carriers, oceanographic research vessels, product tankers, ferry boats, pad- dlewheel casino boats and U.S.

Navy Sealift vessels.
