The 46.1 MW and 52.7 MW marinated gas turbine modules are built and tested to United States Navy shock requirements and are certified by Lloyd's Register NVR and RINA.
These gas turbines produce low emissions, can operate on a variety of fuels, and can be positioned almost anywhere on the ship to increase revenue-generating cargo or passenger space. These gas turbines are designed for applications requiring high power. Both are ideal for FPSOs, LNG carriers and yachts
The 4.1 MW marine gas turbine
The 46.1 MW marine gas turbine offers simple-cycle, two-shaft performance derived from GE's CF6-80C2 high-bypass turbofan aircraft engine.
The engine takes advantage of the CF6-80C2 low-pressure system's normal operating speed of 3600 rpm and includes features like:
- Loads directly to the low-pressure turbine shaft, allowing the commonality of the CF6-80C2 and the 46.1 MW gas turbine to be maintained
- Low-pressure compressor with independently controlled variable inlet guide vanes
- High-pressure compressor with variable stator vanes to modulate airflow, ensuring fast, easy start-up and shutdown – even under partial loads.
The results are low-cost, field-proven parts for the 46.1 MW gas turbine.
More than 1,000 46.1 MW units have shipped, logging more than 21 million operating hours. It is in use on floating production storage and offloading vessels, offshore platforms and power barges in marine environments.
The 52.7 MW model
The same engine is available with a 52.7 MW rating.
The 52.7 MW (PG model) operates at 3850 rpm and has the advantage of much higher output. GE has developed a mechanical drive package for a variety of off-shore projects where space is at a premium.
It is particularly suitable especially for FPSOs below deck applications to free up valuable space on the upper deck
