20 February 2017

Today South Stream Transport B.V. and Allseas Group S.A. signed in Amsterdam a contract to build the second line of the TurkStream gas pipeline’s offshore section. The document is signed within the framework of an option envisaged by the contract for the first line signed in 2016.

Allseas will use the world’s largest construction vessel — Pioneering Spirit for laying 930 kilometers of pipes of the second line across the seabed as well as for carrying out works for the first line.


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.
