Marine Aeroderivative Gas Turbines News

GE Marine reported that the United States Navy has ordered eight Digital Fuel Control (DFC) kits for LM2500 marine aeroderivative gas turbines. The DFC kits provide for improved gas turbine reliability and maintainability, yielding lower maintenance and reduced long term costs. The eight LM2500s, to be retrofitted, will power U.S. Navy DDG Arleigh Burke-class destroyers. The DFC kits incorporate the most state-of-the-art controls available for GE LM gas turbines – a technology now standard on new LM2500, LM2500+ and LM2500+G4 engines.

GE Marine said it will provide Austal USA, Mobile, Ala., with four LM2500 marine aeroderivative gas turbines to power the United States Navy’s 14th and 16th Independence-variant Littoral Combat Ships (LCS). GE is providing 20 LM2500 gas turbines for the Austal USA LCS program, part of a contract for up to 10 ships over a five-year period. The Austal-built LCSs are powered by two LM2500s arranged in a combined diesel or gas turbine configuration with two diesel engines. According to Austal, Coronado (LCS 4) will complete sea trials later this spring.

GE Marine announces it has delivered two LM2500 marine aeroderivative gas turbines to Austal USA’s Mobile, Alabama, shipyard. These units will power the United States Navy’s Independence-variant Littoral Combat Ship Jackson (LCS 6). GE will provide 20 LM2500 gas turbines for the Austal USA LCS program, part of a contract for up to 10 ships over a five-year period. Similar to the previous two Austal-built LCS Independence and Coronado, Jackson will be powered by two LM2500s arranged in a CODAG configuration with two diesel engines.

GE to Supply United States Navy with Additional LM2500 Digital Fuel Control Retrofit Kits. One kit for T-AOE-8 Fast Combat Ship Retrofit. GE Marine reports that the United States Navy has ordered an additional 16 Digital Fuel Control (DFC) kits for LM2500 marine aeroderivative gas turbines. The DFC kits provide for lower maintenance costs, increased reliability and better system response. The 16 LM2500s to be retrofitted power the U.S. Navy’s CG-47 Ticonderoga-class cruisers and DDG-51 Arleigh Burke-class destroyers, as well as the T-AOE-8 fast combat ship. The DFC kits incorporate the most state-of-the-art controls available for GE LM gas turbines – a technology now standard on new LM2500 and LM2500+ engines. Previous-generation LM2500s use a hydro-mechanical control system.

GE Marine reports it has completed a gas turbine engine qualification testing program for its LM2500+G4 marine aeroderivative gas turbines. As a result, the engine is now certified by three key organizations: Bureau Veritas, RINA S.p.A., and American Bureau of Shipping (Naval Vessel Rules). “To meet engine qualification requirements for the LM2500+G4, GE devised a rigorous testing program that was approved by all three key organizations,” said Brien Bolsinger, GE Marine general manager.

GE Marine reports that the United States Navy has retrofitted nearly 50 LM2500 marine aeroderivative gas turbines with GE’s Digital Fuel Control (DFC) kits. The LM2500s power the U.S. Navy’s CG-47 Ticonderoga class cruisers and DDG-51 Arleigh Burke class destroyers. The U.S. Navy incorporated the DFC retrofit into a concurrent ship system modernization program. Since the first digital fuel controls were installed, the U.S. Navy has accumulated more than 100,000 DFC operating hours on selected DDG-51 and CG-47 class ships. In addition, the U.S.

GE Marine announces that its LM2500+ marine aeroderivative gas turbines have been selected by Northrop Grumman Shipbuilding (NGSB), , to power the U.S. Navy’s new LHA 6 amphibious assault ship. The LHA 6 ship’s hybrid mechanical-electric propulsion system will consist of two LM2500+ gas turbines, each rated at 35,290 shaft horsepower at U.S. Navy standard day conditions (100oF), and two, 5,000 horsepower auxiliary propulsion motors. The LM2500+ gas turbines will be manufactured at GE’s Evendale facility.

GE Marine Engines announced it has extended its Marine System Supplier (MSS) agreement with MTU Friedrichshafen (MTU), covering MTU's packaging and distribution of GE LM marine aeroderivative gas turbines. "Our successful MSS agreement with MTU dates back to the 1970s," said Karl Matson, general manager of GE Marine Engines. "This relationship has made it possible for our LM1600, LM2500 and LM2500+ gas turbines to be used alone or in combination with MTU diesel engines from their full line of diesel engines. GE LM gas turbines cover the power range from 4,500 kilowatts (kW) to 42,700 kW. To date, MTU has packaged several GE LM gas turbines for commercial fast ferries and military vessels.

Three Vericor Power Systems' TF50 marine aeroderivative gas turbines have been selected to power the 118 Wallypower high-speed yacht being built by Intermarine Shipyard, Sarzana, Italy for Wally Yacht. This is Wally Yacht's first foray into high-speed power yachts, and the company's initial application of gas turbines. Wally Yacht, based in Monte Carlo, Monaco, is a world-renowned designer of high-speed sailing and power yachts. The 118-ft. yacht will feature three TF50 gas turbines in a Combined Diesel Or Gas (CODOG) turbine configuration. Two TF50s will be used as side or "wing" engines, with one small auxiliary diesel engine connected to each wing engine. The diesels will provide for very slow maneuvering only.
