What is Subsea Integration Alliance

Amplify Subsea Performance

​Subsea Integration Alliance continuously enhances individual capabilities, products and project delivery within subsea production systems (SPS) and subsea umbilical, riser and flowline (SURF) systems. Together, as Subsea Integration Alliance, we have further expanded our capabilities towards the integrated delivery of projects.

At the same time, we have significantly adapted our engagement models – allowing us to interact earlier with customers, and to support them in choosing the system, and product solutions that best match their project needs.

Subsea Integration Alliance brings these initiatives together into a fully integrated subsea offering.

Uncover the true value

Early collaborative engagement utilising our subsea value framework enhances investment returns across subsea projects.
