USA: GE Marine has completed a gas turbine engine qualification testing programme for its LM2500+G4 marine aeroderivative gas turbines.
The engine is now certified by three key organisations: Bureau Veritas, RINA and American Bureau of Shipping (Naval Vessel Rules).
"To meet engine qualification requirements for the LM2500+G4, GE devised a rigorous testing programme that was approved by all three organisations," said Brien Bolsinger, GE Marine General Manager.
"The 500-hour programme test cell certified the engine's operation and performance thus qualifying the LM2500+G4 gas turbine for both military and commercial marine applications," Mr Bolsinger added.
The first military marine application of the LM2500+G4 will be to power the French and Italian Navies European Multi-Mission Frigates (FREMM) ships.
In September 2008, the initial LM2500+G4 gas turbine module was delivered by GE Marine System Supplier (MSS) Avio to DCNS' shipyard in France for the French Navy's first FREMM.
The LM2500+G4 is the latest member of the LM2500 family. The LM2500+G4 offers 17 percent more power than its LM2500+ predecessor, and has a six percent increase in airflow over the current LM2500+ model.
The LM2500+G4 is expected to provide the same 99.6 percent reliability level as the LM2500, which currently has a fleet of more than 2,500 engines operating in diverse marine and industrial applications.
