New Italian Navy FREMM Frigate Powered by GE LM2500+G4
EVENDALE, Ohio — GE’s Marine Solutions reported May 11 that the seventh multipurpose FREMM frigate, Federico Martinengo, was recently delivered to the Italian Navy by shipyard Fincantieri. All of the Italian Navy’s new Carlos Bergamini-class FREMM frigates feature the same power dense GE LM2500+G4 gas turbine in a COmbined Diesel eLectric And Gas turbine (CODLAG) propulsion system.
In 2013, Fincantieri delivered the first Italian FREMM, Carlo Bergamini. Fincantieri ship designs using GE LM2500 family of engines are being considered by other international navies including the United States’ new guided-missile FFG(X) frigate and Australia’s SEA 5000 frigate. GE has delivered more than 700 marine engines to the U.S. Navy, providing 97 percent of the commissioned propulsion gas turbines for this fleet. The Royal Australian Navy also has extensive experience and an established logistics support program in place for GE LM2500 family of engines.
The GE LM2500 family includes the base LM2500 (25.1 MW), the LM2500+ (30.2 MW) and the LM2500+G4 (35.3 MW). To date, 1,450 GE gas turbines have been delivered onboard 646 naval ships serving 35 navies worldwide. The large worldwide fleet of GE marine and industrial gas turbines has a 98 percent availability and 99 percent reliability.
Separately, GE LM2500+G4 marine gas turbines will soon power the Italian Navy’s new Pattugliatori Polivalenti d’Altura (PPA) multipurpose offshore patrol ships. GE’s contract includes an order for seven LM2500+G4 gas turbines. The ship’s flexible and unique hybrid propulsion plant will feature small gearbox-mounted motors for low-speed operations, two propulsion diesels for midspeed service and the LM2500+G4 gas turbine to reach 32-plus knots. GE also will be responsible for the electrical system integration of the hybrid system.
The LM2500+G4 gas turbines will be built in Evendale, Ohio. Avio Aero will manufacture the LM2500+G4 turbine control system at its facility in Brindisi, Italy, and GE Power Conversion will manufacture the drives.
