GE Marine Gas Turbine Powers World’s Fastest ship and Largest Ocean Liner

Released August 1, 2013

GE’s family of LM2500 marine gas turbines might be nearly five-decades old but they seem to be still  oozing versatility and raw youthful power which appears all the more evident by them being incorporated in some of the world’s best marine vessels till date.

GE’S LM2500 turbines power the Francisco, the world fastest ship, and well as the Queen Mary 2, the largest ocean liner ever built, and the U.S. Navy’s first hybrid vessel, USS Makin Island. The LM2500 marine gas turbine is GE’s most widely applied gas turbine. It powers more than 400 ships in 30 world navies, fast ferries, coast guard cutters, supply ships and cruise ships.

GE designed the LM2500 turbine around an engine core developed for the CF6 jet engines, which still power many Boeing 747 jumbo jets. Although a lot has changed since the first turbine entered service in 1969, the design has proved remarkably hardy. The fourth generation of the turbine delivers more than 47,000 shaft horsepower at the same high efficiency as its predecessors.

The LM2500 marine gas turbine is a simple-cycle, high-performance engine that consists of a gas generator, a power turbine, attached fuel and lube oil pumps, a fuel control and speed governing system, associated inlet and exhaust sections, and lube and scavenge systems, as well as Controls and devices for starting and monitoring engine operation.

The LM2500 marine gas turbine is frequently housed in a high-shock resistant, thermal, acoustic enclosure on a mounting base. The enclosure attenuates noise in the engine room and provides sensors for inlet icing and fire detection.

The simple modular design of the LM2500 incorporates many features to maximize shipboard maintainability and parts replacement downtime, such as a split compressor casing, in-place blade and vane replacement, in-place hot section maintenance and accessible external fuel nozzles.

The Francisco holds the distinction of being the world’s first high-speed ferry that uses liquefied natural gas (LNG) as primary fuel. Sources say that the ship is the “fastest, environmentally cleanest, and most efficient high-speed ferry in the world.”
