HOUSTON, Mar. 3
-- Chevron Australia awarded contracts to units of GE to supply equipment for the Gorgon LNG project on Barrow Island in Western Australia.

GE Oil & Gas will supply equipment for LNG refrigeration, carbon dioxide sequestration, and power generation. In addition, GE Oil & Gas’s Drilling and Production will supply subsea production equipment to be installed in 200-1,350 m of water 60-140 km off Barrow Island. This award is made under a 5-year frame agreement signed in May 2008 to supply subsea equipment and support services for Gorgon.

Building on a $400 million contract announced late last year, GE will supply equipment to fulfill Gorgon’s LNG refrigeration, CO2 sequestration, and power needs:

• Five 130-Mw Frame-9 gas turbines, modularized, to meet power generation needs of Barrow Island’s gas treatment and liquefaction.

• Three main refrigerant compression trains driven by six Frame-7 gas turbines required for Gorgon’s production of 15 million tonnes/year of LNG.

• Six compression trains to power Gorgon’s CO2 sequestration project.

GE said in its announcement the Frame-9 turbines will be manufactured in Belfort, France, and in Florence. They will then be preassembled into modules, with all controls and auxiliaries, and tested in Massa, Italy, before being shipped to Australia between July 2012 and mid-2013.

The Frame 7 mechanical drive gas turbines will be manufactured in Greenville, SC, while the main refrigerant compressors will be manufactured in Florence and Massa, where the complete trains will be string tested. The CO2 train will be fully built and tested in Florence.

In addition, GE will supply Chevron with equipment to produce gas from offshore Gorgon and Jansz fields:

• Twenty 7-in. VetcoGray subsea trees with retrievable choke modules to control and manage gas production.

• Twenty VetcoGray subsea wellhead.

• Production controls systems to monitor and control the complete subsea infrastructure, controlled from Barrow Island.

• Five pipeline termination systems, five manifolds, 34 pipeline end terminations, and several other structures, including pig launchers/receivers and umbilical distribution assemblies, 45 spools, and 18 multibore well jumpers.

• Complete scope will total about 10,000 tons of structures.

First equipment deliveries are planned for second-quarter 2011.
