GE offers electric start for gas turbines
GE’s Marine Solutions is now offering electric start systems for its line of aeroderivative marine gas turbines, the company announced on 11 January.
The electric start system has been developed as an alternative to hydraulic start systems for GE's LM2500, LM2500+ and LM2500+G4 engines, and is also available for the LM6000PC and LM6000PG gas turbines.
The system includes an integrated clutch design included with the module. The electric start system requires only a single cooling interface on the module with the option for either fresh water or mineral oil cooling mediums. It meets ABS Naval Vessel Rules certification for the US Navy, specifically for shock, vibration and electromagnetic interference.
Brien Bolsinger, GE’s vice president and general manager marine operations, said: 'Our LM2500+G4 gas turbines – the most power dense marine module in the world – were selected for the Italian Navy’s new Pattugliatori Polivalenti d’Altura multipurpose offshore patrol ships. This will be the first use of GE’s electric start system for the LM2500-engine family.
'Benefits with our electric start system include an 82% decrease in footprint and an 85% reduction in weight compared to a hydraulic start system.'
The new system is also being used on the LM500 gas turbines that power the Republic of Korea’s PKX-B patrol boats.
