UNITED STATES OF AMERICA —Subsea engineering and construction contractor Subsea7 S.A. (SUBSEA7) has secured a contract award from Kosmos Energy Gulf of Mexico Operations, LLC (KOSMOS) to execute subsea tieback infrastructure for the Tiberius Project in the United States Gulf. Located in lease block KC-964 at a water depth of approximately 2,200 meters, the development connects deepwater production assets to existing regional host facilities.
Subsea7 S.A. (SUBSEA7) is a global offshore energy services company specializing in subsea engineering, construction, and field development services for the oil, gas, and renewable energy industries. Kosmos Energy Gulf of Mexico Operations, LLC (KOSMOS) is the deepwater operating subsidiary of Kosmos Energy, an international full-cycle upstream oil and gas exploration and production company active across the Atlantic Margin.
Under the terms of the agreement, Subsea7 S.A. (SUBSEA7) will manage the fabrication, transportation, and installation of a 14-kilometer steel catenary riser and wet-insulated flowline linking the Tiberius field to the Lucius Spar host facility, alongside the installation of an umbilical and subsea control systems. Project management and engineering operations are scheduled to commence immediately at the contractor's Houston, Texas office, ahead of offshore installation campaigns slated to begin in 2028.
This deepwater tieback underscores ongoing operator preference for capital-efficient infrastructure expansions that leverage existing offshore processing hubs to accelerate production timelines. For deepwater oilfield service providers, subsea equipment suppliers, and energy sector investors, sustained tieback activity in the United States Gulf reinforces backlog visibility, optimizes host facility utilization, and lowers break-even thresholds for ultra-deepwater hydrocarbon developments.
