The world's largest pipelaying vessel, the Pioneering Spirit arrived in Rotterdam, the Netherlands on Thursday.
Marine statistics show the vessel completed the deep-water offshore construction of the first line of the TurkStream natural gas pipeline on April 30.
After the TurkStream job, the vessel left the Turkish coast and headed for Rotterdam where the vessel will be prepared for its next heavy-lift project - the installation of a 22,000-tonne drilling platform topsides for Norwegian Equinor's Johan Sverdrup development on the Norwegian continental shelf.
In the third quarter of 2018, the Pioneering Spirit will return to the Black Sea to complete the second line of the TurkStream project.
The Swiss-based Allseas Group, the owner of the vessel, executed nearly 300 projects worldwide, installing more than 21,500 kilometers of subsea pipeline in water depths ranging from 5 meters to 2,730 meters.
The Pioneering Spirit commenced offshore operations in August 2016 with the removal of a mobile production platform from Norwegian waters.
TurkStream is the vessel's maiden pipelaying project. It commenced deep-water pipelaying operations late June 2017 and up until April 30 was working exclusively for the TurkStream project.
