The collaboration is in the interests of developing technologies and delivering equipment and services to optimise cost and efficiency in subsea well intervention systems.

The parties will work to deliver a fully integrated offering, combining marine support expertise with well access and control technologies.

The objectives of the alliance include the expansion of applications enabled by subsea well access technology and developing specific solutions for deep and ultra-deep water basins, as well as higher well pressure environments.

Helix's specialisation in well intervention and additional support services such as well commissioning, artificial lift support and abandonment from its vessels is also a special consideration for the alliance, seeing as these tasks are usually performed by drilling rigs.

"The future for subsea well intervention and the value creation it brings is still in the early stages of growth, and the potential for pioneering additional methods for value creation is significant," Helix CEO Owen Kratz said.

"I believe that the challenges for creating the technology and delivering it efficiently to the well in a manner that is safe and protects the environment is best achieved by this collaboration of skill sets from OneSubsea, Schlumberger, and Helix. We are excited about the possibilities."
