  • Publication number: 20220412046
    Abstract: A plough for inserting a cable into a trench in the seabed is disclosed. The plough comprises a plough share for forming a trench in the seabed and a drawbar for enabling attachment of tensile members to the plough. The drawbar is moveable relative to the plough share between a first position, in which the plough is adapted to be towed by a towing cable to move the plough share relative to the seabed to form a trench, and a second position, in which the plough is adapted to be supported by the towing cable to enable the plough apparatus to be deployed to the seabed. A cable path receives the cable and an attachment part of the drawbar is moveable relative to the plough share between the second position and a third position, to enable the cable to be received in the cable path from above the plough.
