Türkiye Welcomes Sixth Vessel to Secure Black Sea Gas Future
Bosphorus News Energy Desk
Türkiye’s national energy initiative reached a historic milestone this week with the arrival of its sixth deep-sea vessel, the Seven Vega, at the southern port of Mersin on Wednesday. While the country’s existing drillships (Fatih, Yavuz, Kanuni, and Abdülhamid Han) continue their exploration and drilling efforts, the newly acquired vessel is the lynchpin for the next, critical stage of commercializing the massive Black Sea gas reserves.
The vessel is a specialized deepwater reel-lay ship, designed not for drilling, but for laying the massive subsea pipelines necessary for Phase II development of the Sakarya Gas Field. Its mission is to connect new wells to the recently dispatched Osman Gazi Floating Production Unit (FPU), setting the stage for an unprecedented increase in domestic natural gas production.
Energy and Natural Resources Minister Alparslan Bayraktar confirmed the vessel's arrival and underscored the sheer scale of the nation's energy ambitions.
"Our 6th drillship to operate in the Black Sea will also be in Mersin on Wednesday," Minister Bayraktar announced, detailing the government’s aggressive timeline. “Our goal in the second phase is to reach a production of approximately 10 million cubic meters [additional] and increase the gas needs met for 4 million households to 8 million households. We will complete Phase Three, which will quadruple this, in 2028.”
Cranking Up the Volume: From 9.5 to 20 Million Cubic Meters
The transition from the initial production phase to Phase II represents a dramatic escalation in output capacity.
Current production from the Sakarya Field, which was first brought online in April 2023, has already surpassed early expectations, reaching approximately 9.5 million cubic meters per day (mcmd). This output currently supplies around four million Turkish households.
However, the goal for Phase II is to nearly double that output. Once the Seven Vega completes its complex pipe-laying task—a challenging operation in the Black Sea’s deep waters—and the Osman Gazi FPU is fully operational in its offshore location, Türkiye aims to reach a daily production capacity of 20 million cubic meters.
This 20 mcmd target is a critical intermediate step towards the long-term vision. The full final phase (Phase III), targeted for completion by 2028, aims to push total daily production to 40 million cubic meters.
The Path to Energy Sovereignty
The aggressive development timeline reflects Türkiye's commitment to significantly reducing its reliance on expensive energy imports. With total discovered reserves in the Sakarya Field currently estimated at 710 billion cubic meters (bcm), the domestic supply is projected to cover a substantial portion of the nation’s annual consumption, which currently sits around 50-60 bcm.
The Seven Vega, a highly advanced vessel capable of operating in depths up to 3,000 meters, will perform crucial connections over the coming months. Following its initial preparatory period in Mersin, the vessel will proceed to the Black Sea to begin laying pipelines. This work must be completed before the Osman Gazi platform, which was recently dispatched to the Filyos industrial zone, can be permanently moored and connected in mid-2026.
As Minister Bayraktar noted, these operations—often unseen on the seabed—are crucial steps in transforming the nation’s energy landscape. The ongoing work ensures that Türkiye is not just discovering gas, but efficiently extracting and bringing it to the homes and industries that need it most, solidifying its path toward energy sovereignty.
