HOUSTON– Esso Australia Pty Ltd. has awarded Subsea Integration Alliance EPCIC contracts for the West Barracouta gas project offshore Australia.

This is the first integrated subsea project for Subsea Integration Alliance, a partnership between OneSubsea and Subsea 7, in Australia.

The work scope includes engineering, procurement, construction, and installation of two production wells. The wells are in a water depth of approximately 45 m (148 ft) and will be tied back to the Longford onshore gas plants.

Project management and engineering will be provided by OneSubsea and Subsea 7 from offices in Perth and Melbourne, Australia. Offshore installation activities are scheduled for 2020.

The Subsea 7 scope includes project management, engineering, procurement, construction, and installation of two production wells and a single electrohydraulic umbilical from the Barracouta platform to the West Barracouta drill center.

The OneSubsea scope includes the provision of two vertical monobore on-wellhead production trees, wellheads, controls, and installation and commissioning services.

Don Sweet, president, OneSubsea, Schlumberger, said: “By adopting our supplier-led approach, Esso Australia will leverage our technical specifications as well as standardized configurable products that will allow for shorter lead times, overall lower system costs, and accelerated first gas production.

“Further, Subsea Integration Alliance’s execution strategy will enable Esso to achieve cost and schedule certainty and reduce interface risk.”
