LM500 Turbine Passing The Trials

Posted on February 8, 2012

GE Marine has reported that its LM500 aeroderivative gas turbines have performed successfully during sea trials on the eighth and ninth PK(X) patrol boats in the Republic of Korea (ROK) Navy’s fleet.

Each of the patrol boats use LM500 gas turbines rated 4180 kW in a combined diesel and gas turbine arrangement with diesel engines, GE Marine said. The first PK(X) Yoon Young-ha was launched at Hanjin Heavy Industries’ Busan, ROK shipyard. Nine ships have been delivered to the ROK Navy.

For this ongoing program, Samsung Techwin locally manufactures select parts of the LM500s and assembles and tests the completed engines at its Changwon, Korea factory. In addition, GE provides ongoing support to Samsung Techwin, the shipyard and the ROK Navy throughout installation, sea trials, and commissioning, the company said.

The simple cycle LM500 is a two-shaft gas turbine consisting of a gas generator, a free power turbine and cold end drive capabilities. The 14-stage axial flow compressor offers a 14.5:1 pressure ratio. The LM500 is derived from GE’s TF34 turbofan aircraft engine, and has 90% commonality with the CF34 engine that powers the CRJ100/200 regional jet with more than 14 million hours of operation.
