The 25.1 MW marine gas turbine is a simple-cycle, two-shaft, high-performance engine. Derived from GE’s CF6-6 aircraft engine, the 25.1 MW marine gas turbine 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, lube and scavenge systems, as well as controls and devices for starting and monitoring engine operation.

There are more than 1,300 of GE’s 25.1 MW marine gas turbines in service worldwide. The 25.1 MW gas turbine offers low emissions, the ability to operate on a variety of fuels, and reduced overall maintenance costs over the life of the engine. Potential applications include high-speed ferries, cruise ships and LNG carriers.
