GE to supply 3 aeroderivative gas turbine-generator modules for Chevron floating production unit in GOM
06 July 2011
GE Oil & Gas will supply three customized aeroderivative gas turbine-generator modules to provide reliable electric power for a new Chevron floating production unit that will produce oil and gas from the Jack and St. Malo fields in the Gulf of Mexico, approximately 280 miles south of New Orleans and at a water depth of approximately 7,000 feet.

GE will provide three LM2500+G4 gas turbine generator modules, each mounted on a three-point support base plate, designed with marine corrosion-resistant materials to overcome footprint restrictions and withstand pitch, roll and acceleration forces anticipated for a floating production unit operating in deep waters.
The LM2500+G4 is rated at 36.3 MW power output. It features a 9,184 Btu/kWe-h heat rate, 213 lbs/sec exhaust flow and 945 °F exhaust temperature. It ramps to full power output from cold metal in 10 minutes. LM2500+G4 gas turbines have been installed in cement plants; coke plants, burning Coke Oven Gas (COG); refineries; for gas pipelines; and for offshore oil & gas production.
The LM2500+G4 gas turbines will be manufactured by GE Aero Energy in Evendale, Ohio, while the generator package assembly and testing will take place at GE Oil & Gas’ facilities in Massa, Italy. Shipment of the equipment is scheduled to start in December of 2011, with commercial startup planned by early 2013.
Chevron’s initial development of the Jack and St. Malo fields will comprise three subsea centers tied back to a hub production facility with an initial capacity of 170,000 barrels of oil and 42.5 million cubic feet of natural gas per day.
