Plough

The cable Plough can bury telecommunication cables, power cables and oilfield umbilical either as they are laid, or in a post lay burial mode.

The Plough is primarily intended for use in simultaneous lay and buries operations. For simultaneous lay and burial the lay cable touches down on the seabed ahead of the Plough. As the Plough moves forward it picks the cable up off the seabed and buries it. This technique is made possible by the steering mechanism which allows the Plough to track along the cable without moving it sideways across the seabed. Cables with a low submerged weight may be laid directly into the bellmouth at the front of the Plough. In this mode of operation the Plough is deployed and recovered with the lay cable passing through the Plough and with the tow cable and umbilical connected. The system is diver less in normal operation. Post-lay burial operations will require the use of divers to load and unload the cable on the seabed.
