Abstract

A method for the controlled bending of a submerged pipeline is disclosed. The section of the pipeline which is to be bent is slightly elevated off the sea floor, preferably by buoys attached to the pipeline along its length. The end of the elevated section of pipeline is pulled in to the desired point of termination while a drag force is simultaneously applied to the elevated portion of the pipeline. The applied drag force should be sufficient to create a bending moment which causes the pipeline to bend along a well defined arc. Preferably, dragging means such as chains, cables, or clump weights extending from the pipeline to the sea floor are used to impose the necessary drag force on the pipeline and to control elevation of the pipeline above the sea floor.
