Norwegian engineering firm Aker Solutions said on Friday that its subsea compression technology has been selected by Chevron Australia as the operator of the Gorgon project for the Jansz-Io compression project, offshore Western Australia.

The company said it is in discussions with Chevron to finalise the deal, which is expected to be about NOK7bn ($807.4m).

Chevron decided to pull the trigger on the Jansz-Io subsea compression project earlier this week with a $4bn investment.

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

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

It 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 joint venture between the Australian subsidiaries of Chevron 47.3%, ExxonMobil 25%, Shell 25%, Osaka Gas 1.25%, Tokyo Gas 1% and JERA 0.417%.
