Turkish Petroleum (TPAO) has awarded a consortium of Subsea7, Subsea Integration Alliance, OnseSubsea, SLB and Saipem with a major contract for the second phase of their Sakarya field development offshore Turkey.

Subsea7 defines a major contract as one where Subsea7’s share of revenue is over USD$750 million.

Phase 1 of the project involved the production of natural gas by using the subsea production system from 10 wells. In Phase 2, up to 30 new wells will be drilled, which will be connected to the subsea production system. A new pipeline will also be installed for transporting the additional gas drawn from Phase 2.

“First gas from Sakarya Phase 1 was delivered just 30 months after discovery,” Franck Louvety, Africa, Middle East & Caspian vice president said.  “Subsea7 looks forward to extending this relationship for Phase 2 and continuing our contribution to the development of the energy industry in Türkiye.”

The project scope of the contract, which is for engineering, procurement, construction and installation (EPCI), will cover the subsurface solutions including subsea production systems (SPS), subsea umbilicals and flowlines (SURF).  The contract also includes additional FEED studies and options to further extend the scope of work.

The current scope to be executed by Subsea7 comprises the EPCI of approximately 23 miles of infield flowlines, 29 miles of control umbilicals and associated subsea equipment in water depths of around 6,500 ft.

Production from the Sakarya Phase 2 conventional gas development project is expected to begin in 2026 and is forecast to peak in 2032, to approximately 1,040 MMcf/d of natural gas.

TPAO is the 100% owner of the field.
