Subsea 7 S.A. announced it has been awarded a major contract by Turkish Petroleum Offshore Technology Center (TP-OTC) for the development of phase 3 of the Sakarya gas field, located in the Black Sea off the Turkish coast. The contract covers engineering, procurement, construction and installation of key subsea infrastructure, including umbilicals, risers and flowlines (SURF – Subsea Umbilicals, Risers and Flowlines).

The contract is classified by Subsea7 as “major,” with a value between $750mn and $1.25bn. Project management and engineering will begin immediately from Subsea7’s Istanbul office, further strengthening the group’s local operational capacity in the region.

Strengthening Subsea7’s operations in Türkiye

This contract extends Subsea7’s involvement in Türkiye’s offshore energy development. The Sakarya field represents the country’s largest deepwater gas project and is a cornerstone of its national energy security strategy. Subsea7 had already contributed to earlier phases of the development, consolidating its role in the regional value chain.

David Bertin, Senior Vice President of Subsea7’s Global Projects Centre East, said the contract “reinforces our relationship with TP-OTC” and confirms the company’s ability to deliver “complex offshore projects safely and reliably.”

A project supported by local teams

Execution of the contract will rely heavily on local resources, according to Hulya Ozgur, Subsea7 Türkiye Business Unit Director. She stated that the new award “reflects the capability of our Türkiye team” to deliver efficient offshore solutions, while highlighting the group’s commitment to local content development.

The Sakarya gas field, located about 175 kilometres offshore, is operated by Turkish Petroleum Corporation (TPAO), the parent company of TP-OTC. It is considered a strategic project to reduce the country’s dependence on energy imports.
