Subsea7 has been awarded a substantial subsea installation contract by Chevron Australia for the Gorgon Stage 3 (GS3) development offshore Western Australia.
Under the award, Subsea7 will deliver a full scope of subsea installation services, including project management, engineering, procurement, fabrication, transportation, installation and pre-commissioning of subsea equipment and associated infrastructure. Offshore installation activities will be carried out in water depths of approximately 1,350 m.
The work will support Chevron’s GS3 brownfield expansion of the Gorgon LNG development, one of the largest natural gas projects in Australia. Project management and engineering activities are scheduled to commence immediately from Subsea 7’s Perth office, with additional engineering and technical support provided from the company’s hubs in Kuala Lumpur and Paris.
Offshore operations are expected to begin in 2028, aligning with Chevron’s broader development schedule for Gorgon Stage 3. Subsea 7 classified the award as a “substantial” contract, indicating a value in the range of $150 million to $300 million.
David Bertin, senior vice president for Subsea 7’s Global Projects Centre East, said the contract reinforces the company’s long-standing relationship with Chevron and highlights its capability to execute complex subsea projects in deepwater environments.
The award continues Subsea 7’s active involvement in Australia’s offshore gas sector, where operators are advancing brownfield and tieback developments to extend production life and improve recovery from existing assets.
