GE Marine reports it has completed a gas turbine engine qualification testing program for its LM2500+G4 marine aeroderivative gas turbines. As a result, the engine is now certified by three key organizations: Bureau Veritas, RINA S.p.A., and American Bureau of Shipping (Naval Vessel Rules). “To meet engine qualification requirements for the LM2500+G4, GE devised a rigorous testing program that was approved by all three key organizations,” said Brien Bolsinger, GE Marine general manager.
