PCT No. PCT/GB92/01742 Sec. 371 Date Jul. 22, 1994 Sec. 102(e) Date Jul. 22, 1994 PCT Filed Sep. 22, 1992 PCT Pub. No. WO95/06401 PCT Pub. Date Apr. 1, 1993.A reel pipelaying vessel includes pipe conditioning apparatus at its stern. The pipe conditioning apparatus includes a radius control device for imparting a substantially uniform curve to the pipe after it is unspooled from the reel, straightening apparatus for imparting a reverse bending force to the pipe opposite to the curvature imparted to the pipe by the reel, and apparatus for guiding the pipe into the water after it emerges from the straightening apparatus. The pipe conditioning apparatus 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 apparatus, extending sternwards of the vessel, and arranged to further increase the entry angle of the pipe after it exits the pipe conditioning apparatus. The stinger is curved and is provided with a series of pipe supporting rollers or pipe supporting endless conveyors apparatus. |
