Korea Patrol Boats Get Power

GE, Samsung Techwin secure US$400 million contract with Korea Navy program

Posted on October 16, 2013

GE Marine’s LM500 aeroderivative gas turbines have been selected to power the Republic of Korea Navy’s PKX-B patrol boat program. The LM500 gas turbines will be manufactured in-country by Samsung Techwin at its Changwon, Korea, facility.

The LM500 gas turbines, rated at approximately 4486 shaft kW, will be used in a combined diesel and gas turbine arrangement.

The LM500 is derived from GE’s TF34/CF34 turbofan aircraft engines and has 90% commonality with the CF34 engine that powers the popular CRJ100/200 regional jet. 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.

GE said that – through Samsung Techwin – it expects to provide more than 100 LM500 engines for the PKX-A and PKX-B programs. Samsung Techwin locally manufactures selected parts of the LM500s, and assembles and tests the completed engines.

GE will provide support of the gas turbine, control and reduction gear system to Samsung Techwin, shipyard Hanjin Heavy Industries and Construction, and the ROK Navy throughout installation, sea trials and commissioning. 

The potential gas turbine propulsion system value over the life of the 34-ship PKX-B program is approximately US$400 million. The program will be conducted in two phases.  The first phase is for 16 ship sets, and after completion, Phase II will proceed according to ROK government procedures.
