GE Marine’s aeroderivative gas turbine propulsion systems range from 6,000 to 70,275 shaft horsepower (shp). The GE LM500, LM2500, LM2500+, LM2500+G4, and LM6000 gas turbines are excellent prime movers for mechanical drive, hybrid and all electric propulsion systems. The company is a long-standing supplier to the Turkish Navy, providing 26 gas turbines for propulsion in three ship classes. An additional 31 navies worldwide have selected GE’s proven aeroderivative gas turbines.
GE Marine sells complete propulsion systems for diverse ship applications in both the military and commercial markets. Key differentiators making GE gas turbine system solutions the preferred choice include power density (i.e., high power in a lightweight, small footprint), fuel flexibility (MGO, LNG or dual fuel), and availability of GE’s highly reliable optional Dry Low Emissions technology.
Local Connection
The Turkish Navy’s MILGEM multi-purpose corvettes each feature one GE LM2500 in a COmbined Diesel And Gas turbine configuration. The first MILGEM corvettes TCG Heybeliada (F-511) and sister TCG Büyükada (F-512) were commissioned in 2011 and 2013, respectively. GE expects to provide up to eight LM2500 gas turbines for the MILGEM program. Twenty-four LM2500s also power the Turkish Navy’s Barbaros- and Gabya-class frigates.
Other key GE Marine partners in Turkey include:
- Savunma Teknolojileri Mühendislik Ve Ticaret A.Ş. (STM), Ankara, Turkey, is the program manager for the Turkish Navy’s two new MILGEM corvettes. GE will provide STM with LM2500 gas turbines to power the third and fourth MILGEM ships.
- Tusaş Engine Industries Inc. (TEI), a joint venture with TUSAŞ-Turkish Aerospace Industries, Inc., manufactures high technology parts for GE marine and aviation engines, including parts for the LM2500 gas turbine.
New Technologies/Services
GE Marine is the exclusive provider of Echogen Power Systems’ heat-to-power system to the marine market. This system uses carbon dioxide instead of water to convert the gas turbine or diesel engine exhaust stream to power. This compact, lightweight and economical product enhances all GE propulsion solutions, boosting system efficiency to nearly 50%.
GE’s LM6000 aeroderivative marine gas turbine PC and PG models have received Lloyd’s Register’s Design Appraisal Document to the Marine Naval Vessel Rules (NVR). The LM6000 is the most fuel-efficient simple-cycle gas turbine in its size class, delivering over 40% thermal efficiency.
The PC model produces 42 megawatts (MW)/59,900 shp and the more powerful PG model has an output of 52 MW/70,275 shp. With the Appraisal Document to Marine NVR in hand, there are additional naval marine applications for the powerful LM6000 gas turbine.
Avio Aero of Italy is now a GE business, bringing world-class marine products, services and engineering expertise to GE Marine’s portfolio.
