Abstract
The invention provides a method for laying a pipeline on a floor located under water, wherein a pipe string is lowered from the pipe-bedding installation to the floor, characterized in that the part of the pipe string situated between the water surface and the floor is at least partially supported by a bearing surface or trunk tubes which engage on the pipe string, wherein an axial displacement is realized between the bearing surface on the one hand and the pipe string on the other. A heavy pipeline can hereby be laid on a deep sea-bed, for instance at a depth in the order of magnitude of 1-3 km, and/or the capacity of the draw benches on board the pipe-bedding installation can be reduced.
