Nexans’ cable selected for Jansz-Io Compression project

Nexans has been awarded a significant turnkey contract to supply and install a groundbreaking deep-water high voltage dynamic cable solution for the Jansz-Io Compression (J-IC) project operated by Chevron Australia. 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 percent), ExxonMobil (25 percent), Shell (25 percent), Osaka Gas (1.25 percent), Tokyo Gas (1 percent) and JERA (0.417 percent). The J-IC project will use world-leading subsea compression technology to maintain long-term natural gas supplies to the Gorgon liquefied natural gas (LNG) and domestic gas facilities on Barrow Island. As part of this, 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 1,400m. A 145kV deep-water dynamic cable will provide power from shore to an offshore floating facility that will subsequently power and control the subsea compression. Ragnhild Katteland, Nexans’ Executive Vice President Subsea and Land Systems Business Group, said: “While innovative on its own terms, the high voltage dynamic subsea cables for J-IC will be a major strategic reference and enabler for future projects in floating offshore wind and the electrification of floating offshore facilities.” Nexans will use its new cable-laying vessel, the Aurora, to install the cables for J-IC. The new vessel is state of the art and its high load, carousel capabilities are specifically designed for laying cables in complex, deep-water deployments like the Jansz-Io field. The 135km long high voltage subsea power cable will also be manufactured, tested and installed in one continuous length. To date, Nexans has invested more than €500M in high voltage state-of-the-art manufacturing and installation assets, firmly establishing it as a world leader in cabling solutions for offshore developments (offshore wind, interconnections).
