FIELD: construction.SUBSTANCE: group of inventions relates to underwater pipeline construction. The method of pipeline laying to a reservoir from the pipe laying barge includes the following stages: guiding of the pipeline (2) along the bearing structure (13) of the lay ramps (6) by means of a number of the guiding devices (14); obtaining images of the pipeline (2) in the plane of registration, transverse with reference to the axis of the pipeline (2), on the lay ramp (6) free end; determination, whether the obtained image is within the allowable range (AR) which is pre-set as a function of the bearing structure (13) configuration and the size of the pipeline (2); and generation of an error signal (E) when the obtained image is out of the allowable range (AR).EFFECT: pipe laying method improvement.22 cl, 4 dwg |
