A wheel cutter tractor for inserting a cable into a trench is disclosed. The tractor comprises a wheel cutter for cutting a trench, and tracks for moving the tractor relative to the trench. A cable support tray supports the cable in a first position displaced from the wheel cutter in a direction transverse to a direction of travel of the tractor, and in a second position above the wheel cutter. A cable grab and lifting device transfers the cable into the cable support tray.

Apparatus and method for inserting an elongate object into a trench

A vehicle for deploying a cable into a trench in the sea bed is disclosed. The vehicle comprises a body adapted to move relative to the trench in the sea bed, and a bellmouth for engaging the cable and mounted to the body, wherein the bellmouth is adapted to define an open channel in a direction facing the trench for engaging the cable.

Method and apparatus for inserting an elongate object into a trench in a sea floor

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.

Apparatus for inserting an elongate object into a trench

An apparatus for locating an elongate object in the seabed is disclosed. The apparatus comprises a body and a pair of jetting swords arranged on lateral sides of the elongate object to form a trench in the seabed. Chain cutters arranged on lateral sides of the elongate object cut respective parts of a trench in the seabed and are moveable relative to the body between a stowed position and a deployed position, independently of the jetting swords.

Apparatus for locating elongate object in a trench in a floor of a body of water

An apparatus for forming a trench in a sea floor and/or displacing material on the sea floor is disclosed. The apparatus comprises a body and front skids mounted to the body for engaging the sea floor and supporting the body. The front skids are adjustable between a first mode, in which the front skids engage the sea floor, and a second mode, in which the front skids engage the sea floor adjacent the trench and at the trench walls.

Method and apparatus for forming a trench in a sea floor

From one aspect the invention is a method of classifying waste materials comprising arranging two sieve screens, each having an inlet end and an outlet end, one above the other to define a space there between, arranging the upper screen, to be of coarser mesh size than the lower screen, supplying waste material to be classified to the inlet end of the upper screen, vibrating the screens, and blowing air between the screens from the inlet end and towards the outlet end whereby the waste material being blown away from the outlet ends of the screens, and large heavy material falling under gravity from the outlet end of the upper screen, and separately collecting the separated waste material fractions. From another aspect the invention is an apparatus for carrying out the method described above.
