Seven Arctic is in charge of installing subsea oil and gas hardware, such as manifold structures, piles, production flexibles, and 140 kilometers of umbilical, at the project in the following three months.

Subsea 7 recently contracted Bakker Sliedrecht to equip the heavy construction / flex-lay vessel with a new energy-saving system.

To remind, Turkish President Recep Tayyip Erdoğan announced in August 2020 that significant gas resources had been found in the Tuna-1 well in the Sakarya field.

The scale of the reserves is said to have the capacity to help Türkiye cut its dependence on energy imports if the gas can be commercially extracted and potentially meet the country’s energy needs for 20 years.

Turkish national oil and gas company TPAO revealed in mid-June that the pipelaying for the gas field development had started.

Saipem’s vessel Castoro 10 was in charge of laying and installing the pipes that will carry the natural gas in the shallow water area.

Subsea 7 is responsible for the delivery of subsea pipelines and associated equipment to connect the subsea wells in approximately 2,000-meter water depth to the early production facility (EPF) under a contract won in October last year in a consortium with Schlumberger.

The Sakarya project is expected to achieve first gas in the first quarter of 2023.
