Subsea7 it will incorporate new installation and connection work for the FPU, which will become operational during the third phase of the Sakarya project.
The company again expanded its participation in the development of the Sakarya gas field after receiving a contractual extension from Turkish Petroleum Offshore Technology Center (TP-OTC) linked to Phase 3 of the project in Turkey.
The new scope includes towing, installation and connection of the mooring lines necessary for the future floating production unit (FPU), whose entry into service is planned for 2028.
With this award, the company strengthens its presence in the Black Sea gas development, where it already participates in different stages related to the construction and installation of offshore infrastructure.
Subsea7 adds work for the Sakarya FPU
According to information published by Subsea7 project management and engineering activities will be coordinated from their Istanbul office. Work related to this new contract will begin immediately.
The company classified the contract extension as a large-scale contract, a category it uses for awards valued between $50 million and $150 million.
The new scope of work focuses specifically on the infrastructure required for the future Sakarya FPU, planned tasks include towing the unit, installing and connecting the mooring lines, operations that will form part of the preparations for its commissioning in 2028.
Phase 3 expands the underwater development of Sakarya
Subsea7 had already secured a significant stake in this stage of the project, in August 2025, the company was selected to supply SURF components for Phase 3 of Sakarya.
Subsequently, in March 2026, it received an extension of that contract to develop EPCI work related to approximately 20 kilometers of flexible pipes, 120 kilometers of umbilicals, a rigid production riser and other subsea equipment.
These facilities will be located at depths of approximately 2,200 meters, a condition that reflects the technical complexity of deep-water development in the Black Sea.
The new extension announced in September now expands the company’s role to include operations directly related to the installation and preparation of the floating production unit for commissioning.
Subsea7 maintains its participation in Sakarya
The company involvement in Sakarya dates back to earlier stages of development, in May 2023, Turkish Petroleum awarded an EPCI contract for the second phase of the project to a consortium made up of SLB, Subsea7 and Saipem.
The scope included subsea production systems (SPS) and SURF systems, including umbilicals, risers, and flow lines necessary to control and transport production from the facilities located on the seabed. Later, in May 2024, TP-OTC awarded Subsea7 an additional contract to install Turkey’s first FPU as part of Sakarya Phase 2.
With this new contract extension, the company maintains its participation in both the subsea infrastructure and the floating facilities associated with the next stages of development of the Sakarya gas field.
