GE LM2500 Marine Gas Turbines Power Japanese Helicopter-Carrying Destroyer

EVENDALE, Ohio — GE’s Marine Solutions reported in a May 9 release that the Japan Maritime Self-Defense Force (JMSDF) commissioned its second Izumo-class helicopter-carrying destroyer. The new JS Kaga (DDH 184) is powered by four GE LM2500 marine gas turbines, and was commissioned at the Japan Marine United Corp. shipyard in Yokohama on March 22.

First-in-class JS Izumo (DDH 183) and JS Kaga are the largest surface combatants in the JMSDF fleet. Both feature a combined diesel and LM2500 gas turbine propulsion system, with the gas turbines using GE’s integrated electronic controls. The ships also feature four 4.6-megawatt GE LM500 gas turbine-generator sets.

“Through our long-standing partnership with IHI, GE gas turbines operate in marine and industrial applications throughout Japan. IHI has established complete overhaul capability for both GE’s LM2500 and LM6000 family of engines,” said Brien Bolsinger, GE’s vice president, general manager. “With such a solid installed base, extensive in-country engine support capabilities, proven operating costs and reliability, GE’s LM2500-family of gas turbines is a low risk solution for navies and ideal for the JMSDF’s next-generation frigate program.”

IHI handles in-country design, manufacture and testing of the LM2500 propulsion modules and LM500 gensets for all the JMSDF and GE military marine programs and delivers them to shipyards. Including the new Izumo-class destroyer program, the JMSDF uses LM2500 gas turbines for its Kongou-, Murasame-, Atago- and Hyuga-class ships. IHI has packaged, tested and delivered more than 235 GE LM marine and industrial gas turbines.

Worldwide, GE LM gas turbines are used by 35 navies to power more than 500 military ships. The current global LM fleet totals more than 4,200 engines operating in a variety of marine, oil and gas, offshore platform, floating production, storage and offloading vessels and industrial power generation applications.
