Meeting the challenges of subsea development complexity to deliver long-term success goes far beyond the capabilities offered by any individual service provider. Our response is Subsea Integration Alliance – an alliance like no other.

Who we are

One team approach

Subsea Integration Alliance is a nonincorporated strategic global alliance between Subsea 7 and OneSubsea, the subsea technologies, production and processing systems division of Schlumberger, bringing together field development planning, project delivery and total lifecycle solutions under an extensive technology and services portfolio.

As Subsea Integration Alliance we continuously enhance individual capabilities, products and project delivery within subsea production systems (SPS) and subsea umbilical, riser and flowline (SURF) systems to deliver a fully integrated subsea offering.

Global network

Subsea Integration Alliance has the resources and capabilities to assure delivery of subsea projects of any scale anywhere in the world.

We maintain operational facilities worldwide to support the asset management needs of our global customer base. Each facility is tailored to the asset management requirements of the region it serves.
