The project will produce 15 million metric tons per year of LNG and is the world’s largest carbon dioxide (CO2) sequestration project.
Both performance and full-load tests on the mixed refrigerant (MR) and propane LNG compressor trains (PR) were carried out at GE’s facility in Massa, Italy.
Compressor train, MR includes a FR7 Gas Turbine plus a centrifugal compressor and a 24MW electric motor.
The PR train is composed by a FR7 GT plus the propane compressor of 63MW rated power, the HP MR compressor and a 24MW electric motor.
During internal tests, the unit reached power output higher than 115MW.
The project includes the subsea development of the Greater Gorgon natural gas fields located about 130 km off the northwest coast of Western Australia in water depths of 200 to 1,300m.
The fields will be linked through subsea and underground pipelines to gas treatment and liquefaction facilities on Barrow Island, where the GE LNG compression equipment will be installed.
The Gorgon project is a joint venture that includes the Australian subsidiaries of Chevron with 47%, ExxonMobil with 25%, Shell 25%, Osaka Gas 1.25%, Tokyo Gas 1% and Chubu Electric 0.417%.
