Half of TurkStream offshore section installed

6 March 2018

On 6 March, 50% of the offshore section for the TurkStream Offshore Gas Pipeline has been installed. As of today, over 930 kilometer of pipeline has been laid in total on the seabed of the Black Sea, divided over two strings. Pioneering Spirit, the vessel responsible for the deep-water sections of the pipeline, passed kilometer point 706 this morning for the first line. For the second line, 224 kilometers were installed in 2017.

Construction of the offshore section started on 7 May 2017 by Alseas’ vessel Audacia. On 23 June 2017, Pioneering Spirit took over to install the deep-water section. Pioneering Spirit has been working on the project continuously since then.


TurkStream is the project for a gas pipeline stretching across the Black Sea from Russia to Turkey and further to Turkey’s border with neighbouring countries. The first line of the gas pipeline is intended for the Turkish consumers, while the second line is designated for the Southern and South-Eastern Europe. Each line will have the throughput capacity of 15.75 billion cubic meters of gas per year. South Stream Transport B.V. is responsible for the construction of the gas pipeline’s offshore section.
