<p>A reel pipelaying vessel includes pipe conditioning means at its stern (208). The pipe conditioning means (210) includes radius control means (212) for imparting a substantially uniform curve to the pipe after it is unspooled from the reel, straightening means (214) for imparting a reverse bending force to the pipe opposite to the curvature imparted to the pipe by the reel, and means for guiding the pipe into the water after it emerges from the straightening means. The pipe conditioning means is pivotable about a pivot axis to adjust the pipe entry angle at which the pipe enters the water. A stinger assembly is located at the downstream end of the pipe conditioning means, extending sternwards of the vessel, and arranged to further increase the entry angle of the pipe after it exits the pipe conditioning means. The stinger is curved and is provided with a series of pipe supporting rollers or pipe supporting endless conveyor means.</p> |
