Propulsion Notes S&S To Supply Gensets For Holland America Four of S&S Energy's GE LM2500 aeroderivative gas turbine-generator sets will be utilized by Holland America on four of the line's newbuilds. Scheduled to be constructed at Fincantieri's Marghera shipyard, each 951 ft. (289.8 m), 84,000- ton vessel will be equipped with one of the gensets, operating in tune with one or more of the five diesel generators onboard. This combination enables the vessels to run in environmentally sensitive areas using clean gas turbine power. The vessels will also incorporate a podded drive propulsion system, which provides better maneuverability and enhanced operating efficiencies. Operating approximately 2,500 hours per year, each LM2500 will be fueled by Marine Gas Oil. The turbines will be con- figured with a low-pressure waste heat boiler tapping into each vessel's steam system. Circle 71 on Reader Service Card TRAC Stabilizers Provide Improved Control Known for its TRAC thrusters, Ameri- can Bow Thruster added a high perfor- mance, active fin roll TRAC Digital Stabi- lizer, which monitors rate of roll and heel angle. The system automatically measures ves- sel speed, and quickly adjusts system gain accordingly to eliminate long-standing weakness of traditional stabilizer systems. A specially designed winglet increases lift by 30 percent while lowering drag by 20 percent for optimal performance. While there are no special adjustments mandated for different sea states, the TRAC automatically adjusts to any sea state for maximum stabilization. Available in sizes ranging from 2.5 to 58 sq. ft., TRAC easily integrates with ABT thruster and central hydraulic systems. Circle 14 on Reader Service Card Cole Hersee Introduces Brass Ignition Key Cole Hersee Co., manufacturer of heavy-duty electrical products for the vehicle industry, has introduced the M- 725 switch. This practical device is equipped with shoulders at the key entry that help provide torque from the key to the switch to eliminate shearing of the key shank. In order to keep moisture away from the electrical contacts, the product is filled with o-ring seals. Solid brass screw terminals and chrome-plated hardware complement the switch as well.
