South Stream Transport B.V. signed a contract with Allseas Group today to lay the first line of the TurkStream offshore gas pipeline, with an option for laying the second line.

According to the contract, Allseas is to lay more than 930 kilometers of pipes on the seabed. The company will engage the world’s largest construction vessel, the Pioneering Spirit, for the job. The newly completed vessel is especially equipped for offshore pipe laying, with six welding and coating facilities on board.

Allseas will start laying the first line in the second half of 2017.


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.
