Oslo-listed Subsea 7 has revealed another substantial contract for work in 2019 and 2020.
The company said the deal is worth between $150m and $300m.
But contractual obligations prevent it from giving further details at this time, it added.
Earlier this month, the owner signed a deal with Nexen associated with the Buzzard Phase 2 Project off Scotland.
It will take care of project management, engineering, procurement, construction and installation of a 5km pipeline bundle.
