Abstract:
A gripping device, for gripping underwater pipelines at the laying stage, has jaws that are pressed onto a pipeline extending along an axis-substantially parallel to a laying direction, and have respective friction pads that are brought cyclically into contact with the outer face of the pipeline; and auxiliary gripping tools, which have panels for covering respective friction pads, and are selectively connectable to the jaws to increase grip between the jaws and the pipeline.
