Subsea 7 has boosted its backlog with three deals set to start in 2026.

The new contracts, in the US, the UK and Saudi Arabia, are together worth between $450m and $900m, the company said on Thursday.

Under the US agreement, Kristian Siem-backed Subsea 7 will install a high-pressure, 27-kilometre subsea tieback to the Shenandoah floating production system on the Monument development in the Gulf of Mexico for Texas-based Beacon Offshore Energy.
