Norwegian OSV owner Subsea 7 has clinched a subsea deal with BP worth between $50m and $150m.

It said the SURF (subsea umbilicals, risers and flowlines) contract for the Manuel project in the US Gulf of Mexico will be carried out by its Subsea Integration Alliance.

This is a partnership between Subsea 7 and OneSubsea Schlumberger.

The work comprises a two-well development tie-back to the Na Kika production facility, working at water depths of up to 1,900 metres.

Offshore work will start in the fourth quarter of 2019.
