General information
A Trailing Suction Hopper Dredger is a self-propelled vessel, used for maintaining or deepening waterways, to dredge sands or to replenisch beaches. In other instances using it for capital works e.g. for construction purposes on land. Equipped with powerful pumps the vessel deploys one or two suction pipes fitted with a draghead. Subsequently these dragheads are lowered onto the seabed, whilst the vessel moves slowly forward. Holding the dredged materials in its hopper, the vessel sails to the location , often many miles away from the dredging area to discharge them. This discharging can be done in various was, such as 1) through its bottom-doors, mounted in the keel of the vessel, 2) pumping these ashore, sometimes over distances of more than one kilometer, or 3) by spraying the material over a short distance, also known as rainbowing.
General information
A Cutter Suction Dredger is a stationary dredger equipped with a rotating cutting device (cutterhead). The cutterhead is mounted to the end of a ladder and which cuts the material prior to being sucked up by flow of a powerfull suction pump. In order to move the dredger, two side wire winches pull the Cutter Suction Dredger’s ladder from side to side. In this manner the dredger can rotate horizontally in a radius of about 70-90 degrees. Usually by means of a spud pole, the aft side of the Cutter Suction Dredger is fixed in the horizontal plane to the a certain position on the seabed. Subsequently the material is now sucked up by one or two powerful inboard pumps, which pump the material via a floating line to e.g. a sandfill. In addition, a Cutter Suction Dredger is more suitable to dredge the harder materials.
