Oilfield services firm Schlumberger has signed a deal with Subsea 7 to renew the Subsea Integration Alliance for a further seven years.

Following the deal, the alliance will continue to develop subsea solutions for developments of deepwater projects.

An alliance between Subsea 7 and Schlumberger’s OneSubsea subsea technologies, production, and processing systems business, the Subsea Integration Alliance is engaged in designing, developing, and delivering integrated subsea development solutions.

To deliver the solutions, the alliance uses a combination of subsurface expertise, subsea processing systems, subsea production systems (SPS), subsea umbilicals risers and flowlines systems (SURF), and life-of-field services.

Subsea 7 CEO John Evans said: “Driven by the demonstrable benefits to clients of this mode of collaborating, integrated projects are expected to remain a significant component of the subsea market. We look forward to extending our relationship with OneSubsea as we address the opportunities of the offshore energy market.”

Over the past seven years, the alliance has designed, developed, and delivered integrated SPS and SURF solutions, with potential to optimise the efficiency and cost of the deepwater development projects.

In recent years, the alliance secured major greenfield projects in Australia, Brazil, Africa, and Turkey, as well as contracts for tie-back work in the Gulf of Mexico and Norway.

Schlumberger Core Services and Equipment executive vice-president Abdellah Merad said: “Subsea Integration Alliance has proven to be a tremendous success.

“Having been awarded 12 integrated projects, and more than 130 early engineering studies around the world, it has helped, and will continue to help, customers achieve maximum value from their subsea developments through industry-leading innovation and expertise.”

Earlier this year, Subsea 7 announced that it had received a FEED study contract for the Krafla development project.
