Chevron okays $6bn Jansz-Io Compression project

1014

Chevron Australia and the Gorgon joint venture partners have reached a final investment decision for the $6 billion Jansz-Io Compression (J-IC) project, located approximately 70 kilometres off the north-west coast of Western Australia.

A modification of the existing Gorgon development, the J-IC project will create around 350 construction jobs during the five-year development, and secure the future of around 700 Gorgon project jobs during operations.

The project will involve the construction and installation of a 27,000-tonne normally unattended floating Field Control Station (FCS), approximately 6,500 tonnes of subsea compression infrastructure and a 135km submarine power cable linked to Barrow Island.

Nigel Hearne, Chevron Eurasia Pacific Exploration and Production president, said J-IC will use proven subsea compression technology to help recover gas from the Jansz-Io field to maintain long-term natural gas supply to the LNG and domestic gas plants on Barrow Island.

“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,” Hearne said.

“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.”

Minister for Resources and Water Keith Pitt welcomed the final investment decision for the massive J-IC project, saying it would ensure continued gas supplies to the LNG on Barrow Island, off the northwest coast of Western Australia and for domestic users.

“The decision is a major step forward for the J-IC project, which will create around 350 construction jobs during the five-year development, and secure the future of around 700 Gorgon project jobs during operations,” Mr Pitt said.

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

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