ABSTRACT:
For laying a pipeline in deep water by letting out the pipeline in predetermined sections from a pipe laying barge which is correspondingly advanced in a stepwise manner, the end of the pipeline being assembled is subjected to an adjustable holding force which is regulated downwardly from an upper to a lower limit value simultaneously with acceleration of the pipe laying barge in the laying direction, the regulating parameter being the displacement of the pipeline relative to the pipe laying barge.
