GE has been providing aeroderivative marine gas turbines since the 1950s and has amassed extensive experience serving military and commercial ship applications. GE offers a wide range of engine sizes backed by continual infusion of new technologies to meet ever-changing customer needs. GE’s design-for-maintenance approach is supported by global service experts, ensuring these engines remain the market’s most reliable gas turbines with the lowest lifecycle costs. Our LM marine gas turbines provide superior availability for diverse military applications including United States Navy shock-tested designs and lower shock requirements. These reliable engines are ideal for military ships ranging from 200 to 60,000 tons displacement with applications on patrol boats, corvettes, frigates, destroyers, cruisers, aircraft carriers, amphibious warfare ships, and supply and sealift ships. GE marine gas turbines also have been used on commercial ships since the 1990s. These compact, lightweight engines have the capability to burn a wide variety of fuels, as well as the ability to meet existing and proposed environmental regulations. These features make GE marine gas turbines ideal for LNG tankers, container ships, power barges, cruise ships and ferries. Our COmbined Gas turbine Electric and Steam (COGES) system has the lowest annual operating cost of any propulsion system. The marine gas turbine family shares extensive pedigree with GE’s reliable industrial aeroderivative turbines. There are over 5,000 aeroderivative gas turbines operating worldwide, logging more than 150 million hours in marine, power generation, and oil and gas settings.
