Subsea 7, as part of a consortium, has received a contract from Turkish Petroleum for the second phase of development of the Sakarya field, located in the western Black Sea, offshore Turkey.

In addition to Subsea7, the consortium includes OneSubsea, Saipem, and SLB.

The consortium was awarded the engineering, procurement, construction, and installation (EPCI) contract for the second phase of the Sakarya field.

Under the terms of the contract, the consortium is responsible for the EPCI of subsurface solutions including subsea production systems, as well as subsea umbilicals and flowlines (SURF).  

Subsea7’s contractual scope includes the EPCI of about 37km of infield flowlines, 47km of control umbilicals and associated subsea equipment at a water depth of 2,000m. 

The company is also responsible for performing additional front end engineering design (FEED) studies.

Furthermore, the contract includes options to extend the scope of work.

Subsea7 Africa, Middle East and Caspian vice president Franck Louvety said: “Through the close collaboration of Subsea7, OneSubsea and Turkish Petroleum, first gas from Sakarya Phase 1 was delivered just 30 months after discovery.

“Subsea7 looks forward to extending this relationship for Phase 2 and continuing our contribution to the development of the energy industry in Turkey.”

Subsea7’s share of the contract is more than $750m. The company stated its office in Istanbul will handle project management and engineering scope.

Offshore work is expected to take place between the second and third quarters of 2025.

Subject to a final investment decision, the optional scope is expected to be performed between the fourth quarter of 2026 and fourth quarter of 2027.

The Sakarya gas field project was commissioned last month. It is estimated to have a production capacity of ten million cubic metres of natural gas in the first phase.

The second phase will involve the planned drilling of 30 new wells that will be connected to the subsea production system
