LM2500
An LM2500 on USS Ford(FFG-54)
Type	Aeroderivative gas turbine
National origin	United States
Manufacturer	General Electric
First run	1960s
Developed from	General Electric CF6

The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine.

The LM2500 is available in 3 different versions:

The normal MS7001EA starting device is an 800 hp (600 kW) electric motor driving at 50% overload (short-time) through a torque convert- er and accessories gear-box to the gas turbine. GE does not have any larger starting means avail- able for application at the front end of the MS7001EA that could provide torque assistance.

GE’s Oil & Gas business has long-standing experience in manufacturing gas turbines dating back to 1961 when a manufacturing agreement was established with GE (U.S.A.) to complement the existing portfolio of products for the petroleum and petrochemical industries (reciprocating and centrifugal compressors, gas engines, pumps, valves. This single-shaft turbine is a compact, heavy-duty prime mover designed for long life and ease of operation and maintenance. The three main features of its simple design are a 17-stage, axial compressor; combustion system with 10 chambers capable of burning a wide range of fuels (DLN also available); and a two-stage turbine with high-energy stage.

The LM2500 delivers 33,600 shp (25,100 kW) with a thermal efficiency of 37 percent at ISO conditions. When coupled with an electric generator, it delivers 24 MW of electricity at 60 Hz with a thermal efficiency of 36 percent at ISO conditions.^[1]
The improved, 3rd generation, LM2500+ version of the turbine delivers 40,500 shp (30,200 kW) with a thermal efficiency of 39 percent at ISO conditions. When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions.^[2]^[3]
The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions.^[4]

As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships.^[5] Other uses include hydrofoils, hovercraft and fast ferries.

In 2012, GE developed an FPSO version to serve the oil and gas industry's demand for a lighter, more compact version to generate electricity and drive compressors to send natural gas through pipelines.^[6]

Design and development[edit]

A heavy lift lowers the main propulsion module into the hull of USS Bunker Hill(CG-52) during construction at Ingalls Shipbuilding. The module consists of two General Electric LM2500 gas turbine engines and a Westinghouse gear reduction unit.

The LM2500 was first used on the US Navy GTS Admiral W. M. Callaghan in 1969, after the original FT-4 gas turbines experienced many technical problems.^[7] Later, they were used in US Navy warships in the Spruance class class of destroyers and the related Kidd class, which were constructed from 1970. In this configuration it was rated to 21,500 shp (16,000 kW). This configuration was subsequently used into the 1980s in the Oliver Hazard Perry-classfrigates, and Ticonderoga-classcruisers. It was also used by one of People's Republic of China's Type 052 Luhu Class Missile Destroyer (Harbin 112) acquired before the embargo.

The LM2500 was uprated to 26,500 shp (19,800 kW) for the Arleigh Burke-class destroyers, which were initiated in the 1980s and started to see service in the early 1990s, and the T-AOE-6 class of fast combat tanker.

In 2001 the LM2500 (20 MW) was installed in a sound-proof capsule in the South African Navy Valour class (Meko A-200 SAN) frigates as part of a CODAG propulsion system with two MTU 16V 1163 TB93 Propulsion Diesels.

The current generation was uprated in the late 1990s to over 30,000 shp (22,000 kW).

LM2500 installations place the engine inside a metal container for sound and heat isolation from the rest of the machinery spaces. This container is very near the size of a standard 40-foot (12 m) intermodal shipping container - but not the same, the engine size very slightly exceeds those dimensions. The air intake ducting may be designed and shaped appropriately for easy removal of the LM2500 from their ships.

The LM2500+ is an evolution of the LM2500, delivering up to 40,200 shp (30,000 kW) or 28.6 MW of electric energy when combined with an electrical generator. Two of such turbo-generators have been installed in the superstructure near the funnel of Queen Mary 2, the world's largest transatlantic ocean liner, for additional electric energy when the ship's four diesel-generators are working at maximum capacity or fail. Celebrity Cruises uses two LM2500+ engines in their Millennium-class ships in a COGAS cycle.

The LM2500 is license-built in Japan by IHI Corporation,^{[citation needed]} in India by Hindustan Aeronautics Limited,^[8] and in Italy by Avio Aero.^{[citation needed]}

The LM2500/LM2500+ can often be found as turbine part of CODAG, CODOG, CODLAG propulsion systems or in pairs as powerplants for COGAG systems.
