The offshore part of the pipeline will cross the Black Sea bed. Maximal depth along the route will reach 2,200 m. The length of the offshore part will amount to 910 km.
As planned, the TurkStream pipeline will surface on the shore of the European part of Turkey near Kıyıköy with gas delivery point at Lüleburgaz for the Turkish customers, and a border crossing between Turkey and Greece in İpsala serving as delivery point for the European customers. The length of Turkish onshore section will total 180 km. The capacity of four strings totals up to 63 bcma, including 47 bcma to be supplied to the Turkish-Greek border.
The project complies with all environmental safety standards. The construction and operation technologies for the subsea pipeline foresee minimal impact on the environment, seabed geology, water quality and the habitat for marine fauna, mammals and sea birds as well as fishery.
