Italian Navy Launches Paolo Thaon di Revel, First PPA Multipurpose Offshore Patrol Ship Powered by Hybrid GE LM2500+G4 Gas Turbine Propulsion System
GE Marine's LM2500+G4 gas turbine will soon power the Italian Navy’s new Paolo Thaon di Revel Pattugliatore Polivalente d’Altura (PPA) multipurpose offshore patrol ship.
EVENDALE, OHIO – GE Marine's LM2500+G4 gas turbine will soon power the Italian Navy’s new Paolo Thaon di Revel Pattugliatore Polivalente d’Altura (PPA) multipurpose offshore patrol ship. This efficient hybrid-electric powered ship was launched at a June 15 ceremony at the Fincantieri Shipyard in Muggiano – La Spezia, Italy, and will be delivered to the Italian Navy in 2021.
“A total of seven PPA ships will be built by Fincantieri by 2026, and GE has a contract to provide seven LM2500+G4 gas turbines,” said Mike Reale, Acting Vice President, General Manager, GE Marine, Evendale, Ohio. “The LM2500+G4, with an ISO rating of 35.3 MW and United States Navy rating of 30.3 MW, has found success in the naval market thanks to its selection to power 20 French and Italian FREMM ships and the seven Italian PPA’s. There is interest in the U.S. and abroad in propulsion and generator set applications that rely on the LM2500+G4’s best-in-class power density that is improved with the use of GE’s new fully-shock-qualified, lightweight composite gas turbine module.”
In addition, GE’s Power Conversion business provides the hybrid’s electrification system, including shock-proof MV3000 drives and motors, electrical system integration, energy-efficient PTO/PTI (power take-off/in) and shore power connection functionality. Integration of the electric propulsion system is carried out in support of and in cooperation with Fincantieri. Rounding out the ‘GE Store’ approach for this Italian Navy project, Avio Aero, a GE Aviation business headquartered in Italy, designed the gas turbine packages.
The PPA patrol ship will serve multiple functions from patrol with sea rescue capacity to civil protection operations. It is 133 meters long and can carry 90 crew members with additional accommodations for up to 171 members. The ship’s flexible hybrid propulsion plant features small gearbox mounted-motors for low speed operations, two propulsion diesels for mid-speed service and the LM2500+G4 gas turbine to reach more than 31 knots.
GE in Italy
The PPA program continues a long tradition of LM2500-powered combatants in the Italian Navy with the selection of the LM2500+G4. Starting in 1977, the Italian Navy and Fincantieri were early adopters of GE’s LM2500 gas turbine for the Lupo-, Maestrale-, Artigliere- and Horizon-class frigates, the De la Pen-class destroyers, and the aircraft carriers Garibaldi and Cavour (equipped with GE gears). In 2004, GE’s LM2500+G4 gas turbine was chosen to power 10 FREMM multi-purpose frigates for the Italian Navy.
The LM2500+G4 gas turbines for the PPA program will be built in Evendale; Avio Aero will manufacture the LM2500+G4 turbine control system at its facility in Brindisi; and GE’s Power Conversion business will manufacture the drives.
GE’s marine gas turbine business is part of GE Aviation and is headquartered in Cincinnati, Ohio. GE is one of the world’s leading manufacturers of marine propulsion products, systems and solutions including six aeroderivative gas turbines ranging from 6,100 to 70,656 shaft horsepower/4.6 to 52.7megawatts. These gas turbines reliably operate the world over in some of the most arduous conditions in temperatures ranging from -40 to 120 degrees F/-40 to 48 degrees C.
