Half of the offshore section for the TurkStream Offshore Gas Pipeline has been installed. Namely, 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 conducting deep-water sections of the pipeline, passed kilometer point 706 for the first line. For the second line, 224 kilometers have already been installed in 2017.
The construction of the offshore section started on 7 May 2017 by Alseas’ vessel Audacia. On 23 June 2017, Pioneering Spirit started the installation of the deep-water section, and has been working on the project since then.
The TurkStream Offshore Gas Pipeline will have two parallel gas pipelines stretching for 930 kilometres across the Black Sea, each with a diameter of 81 centimetres and an annual throughput capacity of 15.75 billion cubic meters. TurkStream will be the first pipeline of its size to be installed at a water depth of up to 2,200 metres. One of the pipelines will serve the Turkish market, while the other will deliver Russian gas to south and south-east Europe.
According to the schedule, first gas is expected to flow through TurkStream by the end of 2019.
