A Trailing Suction Hopper Dredger is a self-propelled vessel, used for maintaining or deepening waterways, or to dredge sands to replenisch beaches or to be used for construction purposes on land, thereby using powerful pumps and deploying one or two suction pipes fitted with a draghead, which are lowered onto the seabed, whilst moving slowly forward. The dredged materials are held in its hopper, to be discharged at the intended location, often many miles away from the dredging area, 1) through its bottom-doors, mounted in the keel of the vessel, 2) to pump these ashore, sometimes over distances of more than one kilometer, by means of a quick coupling mechanism, usually mounted at the bow of the vessel, or 3) spraying the material over a short distance, also known as rainbowing

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
