Turkish Petroleum Corp. (TPAO) has let an engineering, procurement, construction, installation, and commissioning (EPIC) contract to Wison New Energies Ltd. for the floating production unit (FPU) to be utilized as part of Phase 3 of Sakarya gas field development.
Sakarya lies about 170 km offshore the western Black Sea in block AR/TPO/KD/C26-C27-D26-D27 in 2,150 m of water. It is Türkiye’s largest-ever natural gas discovery and contains 405 billion cu m proven gas reserves. It was discovered in August 2020 and is being developed in three phases by TPAO.
The gas field development project includes an offshore production system on the seabed, an onshore gas processing unit, and a 170-km pipeline system connecting the two.
The FPU must comply with deepwater operations and navigate the Bosphorus Strait's 56-m air draft restriction. It will be anchored to the seabed in four groups with a total of 20 rope systems in an area about 180 km offshore where it will remain stationary.
The unit is designed with a gas export rate of 25 MM std cu m/d (883 MMscfd), a produced water treatment capacity of 1,350 cu m/d, and a MEG regeneration and injection capacity of 2,503 cu m/d for hydrate inhibition, with a minimum 30-year design life.
It is expected to be commissioned in mid-2028 with Phase 3 starting commercial production in 2030. Total Phase 3 production is expected to reach 40 million cu m/d.
TPAO is operator of the field and holds 100% interest.
