Chevron Australia has let a contract to ABL Group to provide marine warranty survey services for the Jansz-Io compression project offshore Western Australia.
Part of the original development plan for the Chevron Australia-operated Gorgon project, the Jansz-Io compression project involves construction and installation of a 27,000-tonne normally unattended floating field control station offshore western Australia. In addition, the development includes about 6,500 tonnes of subsea compression infrastructure, at 1,350 m water depth, and a 135-km-long submarine power cable linked to Barrow Island.
ABL’s Australian operations will act as marine warranty surveyor to oversee the safe delivery of transportation and installation operations across four work packages related to offshore installation, construction and marine transportation operation of the field control station and high-voltage power and communication transmission system, plus marine transportation of other high value and general project cargo.
The subsea gas compression technology used at Jansz-Io field is expected to enhance recoverability of natural gas from the field and maintain supply to gas processing infrastructure on Barrow Island, ensuring Gorgon continues to deliver natural gas to customers in Western Australia and Asia.
The Gorgon project is operated by Chevron Australia and is a joint venture of the Australian subsidiaries of Chevron, ExxonMobil, Shell, Osaka Gas, Tokyo Gas, and JERA.
