First floating gas platform Osman Gazi set to cross Bosphorus

By News Centre

Türkiye is set to mark the anniversary of the conquest of Istanbul with a major energy milestone: the nation’s first floating natural gas production platform, Osman Gazi, will pass through the Bosphorus tomorrow on its way to Filyos Port.

With its arrival in the Sakarya Gas Field scheduled for mid-2026, the Osman Gazi platform will significantly boost Türkiye’s offshore natural gas production. The platform is expected to double the current daily output in the Black Sea from 9.5 million to 20 million cubic meters, enough to meet the natural gas needs of approximately 8 million households.

Spanning nearly 300 meters in length and capable of processing 10.5 million cubic meters of natural gas per day, Osman Gazi will become a vital asset in Türkiye’s offshore energy infrastructure. It will operate in the Sakarya Gas Field for 20 years, transferring processed gas to land through a 161-kilometer pipeline, where it will be fed into the national grid.
The platform, which underwent extensive renovation at a shipyard in Çanakkale from September 2024 to May 2025, departed from dry dock on May 27. It will make its 11-hour passage through the Bosphorus on May 29, accompanied by a send-off ceremony at Dolmabahçe Palace led by President Recep Tayyip Erdo?an and Energy Minister Alparslan Bayraktar. The platform is expected to dock at Filyos Port on June 1.

With the launch of Osman Gazi, Türkiye is elevating its position as a regional energy player. The country now possesses one of the world’s largest hydrocarbon fleets, consisting of four deep-sea drilling vessels and two seismic research ships. This includes the high-tech Fatih, Yavuz, Kanuni, and Abdülhamid Han drilling ships, as well as the seismic vessels Barbaros Hayreddin Pa?a and MTA Oruç Reis.
Each vessel contributes uniquely to Türkiye’s deep-sea exploration capabilities. The Fatih, for example, made the largest natural gas discovery in the country’s history in the Black Sea in 2020. The Yavuz, Kanuni, and Abdülhamid Han ships further enhance Türkiye’s ability to conduct ultra-deepwater drilling in challenging environments.

Türkiye’s seismic exploration efforts are led by the Barbaros Hayreddin Pa?a and MTA Oruç Reis ships. These vessels can analyze geological formations up to 15 kilometers below the seabed and are equipped with advanced systems to collect two- and three-dimensional seismic data. They are critical to identifying promising offshore reserves and planning future drilling operations.
With the addition of Osman Gazi, Türkiye transitions from merely exploring and drilling offshore to producing natural gas at sea — a major step toward energy independence.
