Under the 22-year long CSA, GE will provide a range of technology services for the QCLNG plant to ensure reliable production at the plant, which is located off east coast of Australia.

The AUD20.4bn ($21bn) QCLNG project, which will turn coal seam gas into liquefied natural gas is under construction since 2010, and is expected to export the cleaner hydrocarbon energy in the markets from 2014.

BG Group chief executive Chris Finlayson said the company is now more focused on safe and efficient operations of the facilities at the QCLNG plant, as the construction is almost half done.

"Using GE’s technology will contribute to the QCLNG plant being one of the most emissions-efficient facilities of its kind in the world," Finlayson added.

"Liquefied natural gas has an important role to play in the management of global greenhouse gas emissions.

"When used as a substitute for coal, particularly in developing economies, liquefied natural gas from the QCLNG Project could reduce greenhouse gas emissions by more than 35 percent."

The scope of work includes planned and unplanned maintenance of GE’s equipments installed at the plant, including 15 PGT25+G4 aeroderivative gas turbines, 28 centrifugal compressors, gearboxes, generators, and all auxiliaries.

GE will also be responsible for monitoring and diagnostic services, as well as ensuring reliability for the equipment.
