Nord Stream Pipeline
Pipe Carrier Vessel Supplying the Castoro Sei
A pipe carrier vessel supplies the Castoro Sei with concrete coated pipes. Fully coated pipe sections are loaded from stockyards via crane onto a barge which supplies the pipelay vessel out at sea. Each of the stockyards was less than 100 nautical miles from the pipelay vessel. Supply barges can carry either 80 or up to 250 pipe sections in one trip.
