UK-based Subsea 7 and the US-based OneSubsea have signed an agreement to design, develop and provide integrated subsea development solutions.

The companies plan to develop the solutions using their subsurface expertise, subsea production systems (SPS), underwater processing systems, subsea umbilicals, risers and flowlines systems (SURF), and life-of-field services.

As part of the alliance, Subsea 7 will offer its experience and technology in seabed-to-surface engineering with OneSubsea’s reservoir expertise and subsea production, as well as processing systems technologies.

"This combination provides clients with the opportunity to significantly improve subsea field economics over the lifetime of the development."

Both companies’ resources will be combined to collaborate on selected projects, to improve field development planning from the reservoir to the production facility.

The alliance will coordinate with clients to design, develop and deliver integrated SPS and SURF solutions.

According to Subsea 7, the solutions are expected to improve project delivery, recovery, and optimise the cost and efficiency of deepwater developments for the field’s operational life.

Subsea 7 chief executive officer Jean Cahuzac said: "This combination of subsurface, SPS, SURF and life-of-field expertise is unique in its breadth of integrated service offering and provides clients with the opportunity to significantly improve subsea field economics over the lifetime of the development.

"I am looking forward to developing further our relationship with OneSubsea as we will be able to capitalise on the synergies between our strong technology portfolios and develop joint technologies to improve our offering for our clients.

OneSubsea chief executive officer Mike Garding said: "The technology and expertise from Subsea 7 perfectly complements OneSubsea’s ‘pore to process’ business strategy to offer a holistic approach to subsea development solutions."
