Kosmos Energy Awards Subsea7 a 14-Kilometer Subsea Pipeline Contract

en.Wedoany.com Reported - On November 13, Subsea7 announced that it had been awarded a contract by Kosmos Energy Gulf of Mexico Operations, LLC for the development of the Tiberius offshore oilfield, covering the fabrication, transportation and installation of a 14-kilometer steel catenary riser and wet-insulated flowline connecting to the Lucius Spar production facility, as well as the installation of umbilicals and the subsea control system. The project is located in Block 964 of the Keathley Canyon leasing area offshore Louisiana in the U.S. Gulf of Mexico, approximately 400 kilometers south of New Orleans, in a water depth of approximately 2,283 meters.

The contract forms part of the Phase 1A development of the Tiberius project. The scope of work focuses primarily on the tie-back between the subsea production system and the existing production facility, including the steel catenary riser, wet-insulated flowline, umbilicals and subsea control equipment. The pipelines and control system will connect the subsea production wells to the Lucius Spar floating production facility, with the existing platform handling oil and gas processing. The Lucius facility is operated by Occidental Petroleum Corporation, and the Tiberius project partners signed a production handling agreement in the third quarter of 2025.

The Tiberius exploration well was spudded in July 2023, and hydrocarbon-bearing intervals were encountered during drilling, with preliminary fluid and core analyses indicating production potential. The project adopts a phased development plan, with Phase 1A comprising the completion of the already-drilled well. The partners made a final investment decision in March 2026, following the securing of long-lead equipment procurement and the signing of contracts for the fabrication and installation of the subsea production system.

In July 2026, Kosmos Energy completed the transfer of project interests to Navitas Petroleum US. Following the adjustment, Kosmos Energy holds a 33.34% interest and serves as project operator, Occidental Petroleum Corporation holds 33.33%, and Navitas Petroleum US holds 33.33%. Occidental Petroleum Corporation is also responsible for operating the Lucius production facility used by the project.

Subsea7 will commence project management and engineering work at its Houston, Texas office in the United States, with the related work expected to get underway in the coming months and offshore construction expected to begin in 2028. Kosmos Energy previously disclosed that first oil from the Tiberius project is targeted for the second half of 2028.
