Subsea Integration Alliance has landed its first integrated subsea project in Australia, according to a news release.
Exxon Mobil subsidiary Esso Australia Pty Ltd. awarded the alliance—which comprises OneSubsea, a Schlumberger company, and Subsea 7—integrated subsea engineering, procurement, construction, installation and commissioning (EPCIC) contracts, Schlumberger said in a news release. The work scope for the West Barracouta project includes engineering, procurement, construction and installation of two production wells in a water depth of about 45 m. The wells will be tied back to the Longford onshore gas plants.
A final investment decision to develop the project, located in the VIC/L1 Block offshore Victoria, was announced in December by Exxon Mobil. The project aims to bring new gas supplies to the Australian domestic market.
OneSubsea and Subsea 7 will provide project management and engineering from local offices in Perth and Melbourne, Australia. Offshore installation activities are scheduled for 2020.
Subsea 7’s scope includes project management, engineering, procurement, construction and installation of two production wells and an electrohydraulic umbilical from the Barracouta platform to the West Barracouta drill center, the release said. OneSubsea’s scope includes the provision of two vertical monobore on-wellhead production trees, wellheads, controls and installation and commissioning services.
