Pipelay process on Allseas' Pioneering Spirit

| Aegir Deepwater Construction Vessel (DCV) |
Aegir DCV lays pipelines across the ocean floor. Unlike the Pioneering Spirit (video above), the Aegir uses the J-Lay technique which involved assembling the pipe sections in the tower and dropping the new sections out the bottom of the ship. This only works in deep water, but there is plenty of deep water out there.
