Subsea7 has secured a sizeable contract by Shell Offshore Inc. in the US Gulf of Mexico. The company defines a sizeable contract as being between $50m and $150m.

The project involves the engineering, procurement, construction, and installation of a production flowline and related subsea infrastructure at Shell’s Phase 3 Silvertip development, located in the deep waters of Alaminos Canyon, with depths reaching up to 3,000 metres.

The project management and engineering will start immediately at Subsea7’s office in Houston, Texas, with offshore activities expected to begin in 2026.

Craig Broussard, senior vice president for Subsea7 Gulf of Mexico, said: “This new award strengthens our diverse portfolio of deepwater projects in the Gulf of Mexico. We look forward to continuing our collaboration with Shell.”

Meanwhile, Subsea7 announced last week that Seaway7, part of the Subsea7 Group, has signed a vessel reservation deal with Dogger Bank Offshore Wind Farm for the transportation and installation of turbines for the Dogger Bank project, offshore the UK.

To remind, Dogger Bank Offshore Wind Farm is a joint venture partnership between SSE Renewables (40%), Equinor (40%) and Vårgrønn (20%).

The offshore works are expected to begin in 2026.

This represents additional work for Seaway7 at this development, where it is currently installing monopile foundations and transition pieces.

Subsea7 said that “the value related to this substantial agreement will be recognised in backlog in the fourth quarter.”

However, the company defines a substantial contract as being between $150m and $300m.
