Chevron awards Gorgon installations

Offshore staff

LUXEMBOURG– Chevron Australia has contracted Subsea 7 for subsea installations for the Gorgon project offshore Western Australia.

Under the $80-million program, Subsea 7 will deliver and install umbilicals and associated subsea structures from Barrow Island – 56 km (35 mi) off the northwest coast - to the Gorgon and Jansz fields.

The Seven Seas vessel will transport the Gorgon and Jansz umbilicals, respectively 59 km (36.7 mi) and 135 km (84 mi) long, from Europe to Australia.

It will then perform installations in water depths of up to 1,350 m (4,429 ft) using the onboard deepwater flex-lay system.

Up to 70 km (43.5 mi) of trenching will be undertaken from the Rockwater 2, to stabilize and protect the main umbilicals.

Subsea 7’s office in Perth will handle project management and engineering, with offshore operations due to start in early 2013.
