Main features of GE’s 30 MW marine gas turbine are increased power (20%) compared to the 25 MW unit, and the same high availability, reliability and an even higher efficiency (lower SFC). As in the case of GE’s 25 MW gas turbine, the 30 MW unit’s simple modular design provides for easy maintenance with its split compressor casing, in-place blade and vane replacement, in-place hot section maintenance and external fuel nozzles.
This compact and lightweight gas turbine offers low emissions and the ability to operate on a variety of fuels. Ideal applications for the 30 MW gas turbine include high-speed ferries, cruise ships, LNG carriers and yachts.
