Abstract
In undersea laying pipeline which is being unreeled from a ship spool in a plastically deformed state, the pipeline is straightened from the plastic state into a behaviorally elastic state as it is unreeled. The straightened pipeline is dispensed in the behaviorally elastic state through a downstream pipe tensioner while the straightened pipeline upstream of the tensioner is maintained in the behaviorally elastic state. The pipeline laying assemblage may include a flange weld station immediately upstream of the tensioner and/or an anode weld station downstream of the tensioner in the above-waterline freeboard of the ship. The pipeline laying method reduces the number of components and the size and cost of the ships in comparison to conventional systems.
