Subsea 7 S.A. announced the award of a contract valued at approximately $80 million from Chevron Australia Pty Ltd for the Chevronoperated Gorgon Project, offshore Western Australia. The work involves the transportation and installation of subsea umbilicals and structures from Barrow Island – 56km off the north-west coast of Western Australia, to the Gorgon and Jansz Fields.
The Gorgon and Jansz umbilicals are 59km and 135km in length respectively. These will be transported from Europe to Australia onboard the Seven Seas, and then installed from the vessel in water depths of up to 1,350m using the onboard advanced deepwater flex-lay system. A major trenching scope of work, of up to 70km, will also be undertaken from the Rockwater 2, to stabilize and protect the main umbilicals.
Project management and engineering will commence immediately from Subsea 7’s office in Perth, Australia, with offshore operations scheduled to commence in early 2013. Darren Cormell, Subsea 7's Vice President, Australia & New Zealand said: “We are pleased to have been awarded this deepwater contract from Chevron. The Gorgon Project represents an important development for the Subsea Umbilicals market in Australia. This award provides an excellent opportunity for Subsea 7 to build upon our strong local presence and long standing track record of working on significant subsea projects in Australia.”
The Gorgon Project is one of the world's largest natural gas projects and the largest single-resource project in Australia's history. It is operated by Chevron and is a joint venture of the Australian subsidiaries of Chevron (approximately 47%), ExxonMobil (25%) and Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and Chubu Electric Power (0.417%).
