Abstract
A marine J-lay pipelaying system for use on a vessel for laying an offshore pipeline has a J-lay tower, a pipe connecting station, wherein said pipe section is connected to the previously launched pipeline, and J-lay tower bearing means which allow for the pivoting of the J-lay tower with respect to the vessel. The J-lay tower has a free-pivotal mode wherein the J-lay tower is freely pivotable with respect to the vessel so that the J-lay tower has an orientation independent from sea-state induced vessel motions. A pipe section loader is moveable between a loading position, wherein a new pipe section is received, and a erected position, wherein the new pipe section is aligned with the J-lay tower; The pipe section loader is provided with an automatic synchronizing system which—when the pipe section loader is moved from its loading position to its erected position—causes a synchronised pivotal motion of the pipe section loader with respect to the J-lay tower in its free-pivotal mode—at the latest as the pipe section loader reaches its erected position—, so that the new pipe section is aligned with the J-lay tower is in its free-pivotal mode.
