Subsea7 Secures Large Extension for Major Offshore Gas Project Türkiye

Subsea7 has secured a significant contract extension for the Sakarya field development, reinforcing its position as the preferred partner for complex deepwater projects in the Black Sea. By leveraging a proven track record and localized engineering expertise, the company differentiates itself through the ability to deliver fully integrated Engineering, Procurement, Construction, and Installation (EPCI) solutions in ultra-deepwater environments. This latest award, valued between $300 million and $500 million, focuses on connecting the recently discovered Goktepe field to existing Phase 3 infrastructure, a move that optimizes existing assets and accelerates production timelines compared to traditional, fragmented development models.

Infrastructure Expansion for the Goktepe Field
The project involves the development of the Goktepe field as a satellite tie-back to the Sakarya Phase 3 floating production unit (FPU). This expansion is a critical component of Türkiye’s strategy to increase domestic gas production. The technical scope of the work is extensive, requiring the installation of approximately 20 kilometers of flexible pipes and 120 kilometers of umbilicals. Additionally, Subsea7 will install a rigid production riser and specialized subsea equipment designed to operate at extreme depths of 2,200 meters. These components are essential for maintaining reliable flow and communication between the new wells and the primary production hub.

Localized Engineering and Project Execution
A key differentiator in Subsea7's delivery model is the heavy emphasis on regional coordination. All project management and engineering activities are centralized at the company’s office in Istanbul. This localized approach ensures seamless collaboration with the client, Turkish Petroleum Offshore Technology Center (TP-OTC), and allows for a more agile response to the unique geological and logistical challenges of the Black Sea. By managing the project locally, Subsea7 strengthens its long-term presence in the region while directly contributing to the growth of the Turkish energy industry’s technical capabilities.

Strategic Timeline and Energy Security
The integration of the Goktepe field is set to play a vital role in meeting Türkiye’s growing natural gas demand. Following the engineering and procurement phases, offshore activities are scheduled to take place across 2027 and 2028. This extension builds upon a series of successful milestones at the Sakarya field, where Subsea7 has consistently demonstrated its ability to execute complex subsea infrastructure projects. The continued development of these reserves is a cornerstone of the nation’s energy independence goals, with the Goktepe tie-in serving as a vital link in maximizing the output of the country’s largest natural gas resource.
