DESIGN OF A REEL-TYPE PIPELAYING BARGE
Eight and one-half million feet of one-through-six-inch diameter pipe have been laid with the patented Reel Pipelaying Technique since 1962. With this technique, miles of pipe are welded together on shore and spooled onto the reel aboard the barge. Then, the barge moves to the right-of-way and lays continuous lengths of pipe at the rate of one to two miles per hour. A recently completed reel barge can lay pipe with a diameter up to 12 inches. Pipe bending, pipe straightening and other functions are automated to control the quality of the installed pipeline and to allow the pipe to be laid rapidly and efficiently. The pipe handling equipment includes a large reel, and aligner, pipe straightening devices, a tensioner, stanchions, and a guide-shoe. The design parameters for the reel and the guide-shoe are discussed. The effect of reversed bending upon the properties of the pipe has been investigated to determine if there are any technical problems when spooling pipe. Test data recorded during the spooling and laying of 3,500 feet of eight inch diameter pipe is summarized. Overalling, tensile properties, and weld ductility are discussed.
