Method of laying a pipeline from a laying vessel onto the bed of a body of water and laying vessel

摘要

A method of laying a pipeline from a laying vessel into a body of water; the method including the steps of : guiding the pipeline (2) along a supporting structure (13) of a laying ramp (6) by means of a number of guide devices (14); acquiring an image of the pipeline (2) in an acquisition plane crosswise to the axis of the pipeline (2) at the free end of the laying ramp (6); determining whether the acquired image is within an acceptance range (AR) predetermined as a function of the configuration of the supporting structure (13) and the size of the pipeline (2); and emitting an error signal (E) when the acquired image is not within the acceptance range (AR).
