The LM500 Engine
Latest technology & highest fuel efficiency
The LM500 marine gas turbine has the latest in proven design technology and the highest fuel efficiency of any gas turbine in its output class.
The simple-cycle, two-shaft LM500 offers an aerodynamically coupled power turbine, and is similar in design to GE’s proven LM2500 gas turbine.
It’s made with corrosion-resistant materials to provide a mature design with maximum reliability and component life.
The LM500 is basically a CF34 engine without its fan and is very similar in materials. It includes a variable stator compressor driven by an air-cooled, two-stage turbine.
LM500
The 6,130-shp LM500 is adapted from the CF34 engine and has the highest fuel efficiency of any gas turbine in its output class.
