These contracts represent the first integrated subsea project for Subsea Integration Alliance in Australia combining OneSubsea and Subsea 7 expertise in subsea production systems (SPS) and subsea umbilical, riser and flowline (SURF) systems, Subsea 7 said on Wednesday.

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

Project management and engineering will be provided by OneSubsea and Subsea 7 from local 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 centre. 

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.”

Andy Woolgar, Subsea 7 Vice President for Australia & New Zealand, said, “By bringing together complementary technology and expertise, we are able to provide our clients with greater certainty of return on investment and enhanced asset profit potential.”
