LM2500 Turbines in Coast Guard Cutter CODAG Package
GE Transportation’s LM2500 aeroderivative marine gas turbine has been selected for the United States Coast Guard’s newest and largest multi-mission cutter under the Integrated Deepwater System program. The LM2500 will be incorporated into the integrated propulsion system for the U.S. Coast Guard’s new Maritime Security Cutter Large (WMSL). The long-range, multi-mission, extremely versatile high-endurance cutter is part of the U.S. Coast Guard’s Deepwater Program. GE is under contract with Detroit Diesel Corporation, Detroit, Michigan, U.S.A. who is supplying the integrated propulsion system to Northrop Grumman Ships Systems (NGSS).
The propulsion system for each WMSL will feature one GE LM2500 gas turbine in a Combined Diesel and Gas turbine (CODAG) arrangement with two MTU 20V1163 diesel engines. The total CODAG system output is specified to be 48 960 shaft hp. Detroit Diesel will incorporate the LM2500 into the integrated CODAG propulsion system. Fabrication of the first NSC is planned to begin in mid-2004; ship delivery is scheduled in 2006. NGSS has began manufacture of the first of eight WMSLs at its Pascagoula, Mississippi, U.S.A. facility, under contract from Integrated Coast Guard Systems (ICGS), a joint venture of Northrop Grumman and Lockheed Martin. In June 2002, the U.S. Coast Guard awarded the Deepwater contract to ICGS.
