<p>An apparatus for continuously laying a pipeline on the floor of a body of water from a pipelaying vessel includes: a generally cylindrical reel with an axis upon which the pipeline is wound, a stinger provided at the stern of the vessel for guiding the lowered pipeline, a launch device configured to control lowering of the pipeline over the stinger of the vessel and into the body of water. This apparatus further includes a frame supporting the reel and the launch device, adapted to be moveable with respect to the vessel in the longitudinal direction of the pipeline, and a tension device to be mounted between the frame and the vessel, adapted to control the pipeline tension in a predetermined tension range during pipelaying.</p> |
