Subsea Integration Alliance announces the award of integrated subsea engineering, procurement, construction, installation and commissioning (EPCIC) contracts.

Esso Australia Pty Ltd has awarded an integrated subsea engineering, procurement, construction, installation and commissioning (EPCIC) contracts to Subsea Integration Alliance.

The award is 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, according to Schlumberger’s new service.

Subsea Integration Alliance work scope includes engineering, procurement, construction and installation of two production wells. The wells are in a water depth of approximately 45 m 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 center.

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

“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,” said Don Sweet, president, OneSubsea, Schlumberger.

Andy Woolgar, Subsea 7 Vice President for Australia & New Zealand, said, “This award builds on our relationship with Esso and on the reputation of Subsea Integration Alliance to offer clients a quality-focused project execution, with optimized production and improved cost efficiency. 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. This project serves as a step-change of how we work in the region and demonstrates our ability to deliver superior value to the industry.”

Subsea Integration Alliance is a worldwide non-incorporated partnership between OneSubsea, Schlumberger, and Subsea 7 developed to jointly design, develop, and deliver integrated subsea development solutions through the combination of subsurface expertise, subsea production systems (SPS), subsea processing systems, subsea umbilicals, risers and flowlines systems (SURF), and life of field services. Its goal is delivering complementary technology and expertise that help customers extend field life and lower production costs, ensuring greater certainty of recovery and return on the investment.
