Abstract
Dredge with drag pipe, consisting of a number of pipe sections interconnected by hinged joints, whereby drag lines are connected to said hinged joints and to the front and rear end of the drag pipe and furthermore the rotatably supported front end of the drag pipe is guided into vertical guiding elements at the side wall of the ship and the rear end carries the drag head. The dredge contains for each drag line a separate winch, controlled by an electronic control unit for automatically moving the drag pipe outboard, lowering the rising the drag pipe and moving the drag pipe inboard. During the whole dredge operation from the outboard movement of the drag pipe unitl the inboard movement thereof the unwound drag line length of each winch is measured, whereby the electronic control unit determines based on said measured drag line length at each moment the position of the drag pipe.
