The LM6000 Engine

The LM6000 is the most fuel-efficient simple-cycle gas turbine in its size class.

It is a simple-cycle, two-shaft, high-performance gas turbine that is derived from GE's CF6-80C2 high bypass turbofan aircraft engine.

There are two models of the LM6000: The LM6000PC is a 46.1 MW machine, and the LM6000PG has an output of 52.7 MW.

Taking advantage of the CF6-80C2 low-pressure system's normal operating speed of 3600 rpm, the LM6000PC couples loads directly to the low-pressure turbine shaft. This feature allows the commonality of the CF6-80C2 and the LM6000 to be maintained. The LM6000PG operates at 3850 rpm but the big advantage is the additional power in the same size machine.

Both models use low-cost, field-proven parts. The low-pressure compressor features independently controlled variable inlet guide vanes and the high-pressure compressor features variable stator vanes to modulate airflow, ensuring fast and easy startup/shutdown – even under partial loads.

GE has developed a mechanical drive package for the LM6000, making it ideal for military combatant applications requiring more power.

The marine module package design for the LM6000 gas turbine has been certified by Lloyd’s Register and RINA Services.  The LM6000 can also be packaged as a generator set for electric drive applications.

More than 1,200 of these units have shipped or are operating in industrial applications, driving electric generators for utility and industrial power generation and mechanical drive LNG compressor trains. Application examples for the LM6000 include military amphibious ships, floating production offloading vessels and LNG carriers.
