Largest construction vessel of the world enters the Black Sea to work on TurkStream

31 May 2017

Pioneering Spirit has entered the Black Sea today in order to commence pipelaying towards the materialization of the TurkStream Offshore Gas Pipeline project. Pioneering Spirit is a specially designed construction vessel from the fleet of Swiss maritime company Allseas. At a length of 382 meters and a width of 124 meters, Pioneering Spirit is the largest vessel in the world, designed for deepwater pipelaying as well as the installation and removal of large oil and gas platforms.

After arriving in Anapa, Pioneering Spirit will start with preparatory work before deep water pipelaying. Audacia, another vessel belonging to Allseas, has already started pipelaying in the Russian coast earlier in May.


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.
