Chevron has announced that its subsidiary Chevron Australia Pty Ltd., as operator, and the Gorgon joint venture (JV) participants will proceed with the approximately US$4 billion (AUS$6 billion) Jansz-Io Compression (J-IC) project offshore Western Australia.

A modification of the existing Gorgon development, J-IC will involve the construction and installation of a 27 000-t normally unattended floating Field Control Station (FCS), approximately 6500 t of subsea compression infrastructure and a 135 km submarine power cable linked to Barrow Island.

Aker Solutions' subsea compression technology has been selected for the project. Aker Solutions remains in ongoing discussions with Chevron to finalise the contract.

Construction and installation activities are estimated to take approximately five years to complete.

J-IC follows the Gorgon Stage 2 project, which is nearing completion of the installation phase, to supply gas to the Gorgon plant from four new Jansz-Io and seven new Gorgon wells.

The Gorgon Project is a JV between the Australian subsidiaries of Chevron (47.333%, ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and JERA (0.417%).

Nigel Hearne, Chevron Eurasia Pacific Exploration and Production president, said: “Using world-leading subsea compression technology, J-IC is positioned to maintain gas supply from the Jansz-Io field to the three existing LNG trains and domestic gas plant on Barrow Island.”

“This will maintain an important source of clean-burning natural gas to customers that will enable energy transitions in countries across the Asia Pacific region.”
