Subsea7 has secured a contract from Kosmos Energy Gulf of Mexico Operations for subsea infrastructure work on the Tiberius deepwater development in the US Gulf, with offshore installation activities scheduled to begin in 2028.

The project is located in Keathley Canyon Block 964, approximately 2,200 metres below the water’s surface. Subsea7 classified the award as sizeable, a designation covering contracts valued between $50 million and $150 million, without disclosing the exact contract amount.

The scope includes the fabrication, transportation and installation of a 14-kilometre steel catenary riser and wet-insulated flowline connecting the Tiberius development to the existing Lucius Spar production facility. Subsea7 will also install an umbilical and subsea control systems as part of the offshore development.

## Subsea installation scheduled for 2028

Project management and engineering activities are expected to begin in the coming months at Subsea7’s office in Houston, Texas, ahead of the offshore installation campaign planned for 2028.

The subsea infrastructure will provide a connection between the deepwater development and the Lucius Spar, allowing Tiberius to use existing offshore production infrastructure rather than requiring an entirely new standalone production facility.

The Tiberius development is owned by Kosmos Energy, with a 33.34% interest, alongside Occidental and Navitas Petroleum US, each holding 33.33%.

The project partners reached a final investment decision in March 2026, while earlier agreements established the framework for handling production through the Lucius facility.

Craig Broussard, Senior Vice President for Subsea7 US, said the company had developed an installation solution in collaboration with Kosmos Energy.

“Drawing on our deepwater expertise and a closely aligned, collaborative approach, we have developed a cost-effective solution designed to support safe and efficient delivery,” said Broussard.

The award adds to Subsea7’s portfolio of offshore engineering and construction activities in the US Gulf, where deepwater developments continue to require specialised subsea infrastructure and installation capabilities.

The company has not identified the vessels that will undertake the offshore campaign or provided a more specific installation schedule.

The contract marks a further step in the development of Tiberius, with engineering work expected to begin ahead of the planned offshore execution in 2028.
