ABSTRACT:
A process for starting and laying a submergible elongate structure, such as a pipeline, upon the bed of a body of water from a marine vessel, while controlling the bending configuration thereof. The method includes the steps of tensioning a flexible cable between a marine vessel and a submerged hook-up facility, progressively suspending portions of a pipeline from the tensioned cable by means of spaced hangers, and extending the pipeline toward the submerged facility. The process may be employed solely to initially start to lay a submergible elongate structure or the process may be employed to both start to lay a submergible elongate structure and to subsequently lay a submergible elongate structure.
