ABSTRACT:
The forward movement of a pipe-laying vessel when laying pipe offshore is controlled to maintain the position of the pipe as laid on the sea bed as close as possible to the desired track. The position of the touch down point on the sea bed of the pipeline suspended from the vessel is measured at periodic intervals by driving a survey vessel fitted with an echo location device along the already laid line. The measured position of a touch down point is compared with the desired track and any deviation is computed. Further movements of the pipe-laying vessel are adapted to minimize this deviation.
