PARIS – Nexans has received a turnkey contract to supply and install a deepwater high voltage cable for Chevron Australia’s Jansz-Io Compression (J-IC) project.
The J-IC project will use subsea compression technology to maintain long-term natural gas supplies to the Gorgon LNG and domestic gas facilities on Barrow Island.
Nexans will deploy a power and communication transmission system from the shore to the offshore compression facilities, which will sit at a water depth of 1,400 m (4,593 ft). A 145-kV deepwater cable will provide power from shore to an offshore floating facility that will subsequently power and control the subsea compression.
The company’s new cable-laying vessel the Aurora will install the cables. The 135-km (84-mi) long high voltage subsea power cable will also be manufactured, tested, and installed in one continuous length.
In addition, Chevron Australia has contracted SPIE Oil & Gas Services to provide process automation systems integration services for the subsea gas compression system.
The services cover all systems integration engineering associated with the subsea gas compression system and field control station along with brownfield modifications required on the existing Gorgon facilities.
The Jansz-Io gas field is part of the wider Chevron-operated Gorgon development, which has been operational since 2016 and delivers natural gas to customers across Asia and Australia. The 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%).
