A Cutter Suction Dredger is a stationary dredger equipped with a rotating cutting device (cutterhead) mounted to the end of a ladder and which cuts the material prior to being sucked up by flow of a powerfull suction pump. During the dredging process the Cutter Suction Dredger’s ladder is pulled near the cutterhead by two side wire winches from side to side and rotates horizontally in a radius of about 70-90 degrees. At the aft side of the Cutter Suction Dredger is fixed in the horizontal plane to the a certain position on the seabed, usually by means of a spud pole. After the material has been sucked up, it usually enters one or two powerful inboard pumps, which pump the material via a floating line to e.g. a sandfill. A Cutter Suction Dredger is more suitable to dredge the harder materials.
