Abstract
Official abstract text for this publication.
A vessel for laying a pipeline includes a plurality of ramps in the region of the first end of the vessel. The plurality of ramps includes a first ramp which is disposed along the pipelaying path, whose inclination is adjustable and which has a first upstream end and a second downstream end, and a second ramp which is disposed along the pipelaying path downstream of the first ramp, whose inclination is adjustable and which has a first upstream end and a second downstream end. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of S-laying laying a pipeline from a vessel, in which the pipeline is guided along a pipelaying path along which a plurality of workstations are disposed, the vessel having a first mode of operation in which the pipelaying path along the vessel has a relatively small amount of curvature and leaves the vessel at a relatively shallow angle and in which the plurality of workstations include a downstream workstation which in the first mode of opera…
