Subsea7 has announced a sizeable contract award from Kosmos Energy Gulf of Mexico Operations, LLC, for the Tiberius Project in the US Gulf. The company defines a sizeable contract as one valued between USD 50 million and USD 150 million.

Project Location and Setting

The Tiberius development sits in lease KC-964, at a water depth of approximately 2,200 meters. The project is being developed as a deepwater tieback to the Lucius Spar, the existing host facility to which the new subsea infrastructure will be connected.

The Tiberius Project is held in equal thirds among three partners. Kosmos holds a 33.34 percent interest, while Occidental and Navitas Petroleum US, LLC each hold 33.33 percent.

Scope of Work

Under the contract, Subsea7 will handle the fabrication, transportation, and installation of a 14-kilometer steel catenary riser and wet-insulated flowline running to the Lucius Spar. In addition to the riser and flowline, the company will install an umbilical and subsea controls for the development.

The scope covers a full chain of activity from manufacturing through to offshore installation, with the riser and flowline forming the principal export route between the Tiberius field and the Lucius host.

Project Timeline

Project management and engineering are set to begin in the coming months. That early-stage work will be carried out at Subsea7's Houston, Texas, office. Offshore activities are not expected until 2028, indicating a multi-year program between the start of engineering work and the beginning of offshore operations.

Company Comment

Craig Broussard, Senior Vice President for Subsea7 US, commented on the award. "We are proud to work with Kosmos on this deepwater tieback," he said. "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."

Broussard's remarks point to a collaborative working relationship between Subsea7 and Kosmos on the project and to a solution the company describes as cost-effective and designed around safe and efficient delivery.

Contract Classification

Subsea7 categorizes its contract announcements by value band, and the Tiberius award falls into the sizeable category, which the company places between USD 50 million and USD 150 million. The company did not disclose a more precise contract value in its announcement.

Project Partners

The ownership structure of the Tiberius Project brings together three companies with near-identical stakes. Kosmos Energy, whose Gulf of Mexico operating entity awarded the contract to Subsea7, carries the marginally larger share at 33.34 percent. Occidental and Navitas Petroleum US, LLC, each hold 33.33 percent.

Execution Planning

With engineering and project management scheduled to commence from Houston in the months ahead and offshore work targeted for 2028, the award sets out a defined sequence of activity for the deepwater tieback.

The combination of a steel catenary riser, wet-insulated flowline, umbilical, and subsea controls reflects the full set of components required to link the Tiberius development at 2,200 meters of water depth to the Lucius Spar.
