Castoro Sei: Inspection of the Welded Pipes

In a double-joint welding station, two 12-metre pipes will be welded together to form a 24-metre double joint, with a welding pass from both inside and outside. Upon completion, the joint will be inspected by ultrasonic testing to identify possible welding defects. Good welds will be covered with an anti-corrosion coating and the double joint lowered to the seabed in a continuous line by pulling the pipe-laying vessel 24-metres forward while the pipeline sections are kept under tension over the stinger.
