South Stream Transport has awarded Swiss-based Allseas Group a contract to lay the first line of the TurkStream offshore gas pipeline in the Black Sea, with an option for laying the second line.
According to the contract, Allseas is to lay more than 900km of pipes on the seabed. Allseas will engage the world's largest construction vessel, the dynamically positioned Pioneering Spirit, for the job.
Pioneering Spirit is equipped with pipelay equipment that makes it possible to install recordweight pipelines from shallow to ultra-deep water, and has an S-lay tension capacity of 2000-tonne.
The vessel, currently in the Alexiahaven in Rotterdam, is equipped with a double-joint factory, six weldingstations for double joints and six coating stations.
Allseas will start laying the first line in 2H 2017.
