... plough is used to cut a trench in the seabed in which a pipeline is placed and backfilled (Palmer, 1979). The important aspects of plough performance are the velocity at which the plough can be dragged and the cover depth that is achieved (Cathie & Wintgens, 2001). Without sufficient cover depth...
