A stationary dredger is moored by means of anchors and/or spuds, and is swung around the spudpole powered by winches. The main advantages of this type of vessel are its ability to operate in shallow water and to dredge a wide variety of materials. The mentioned spuds and winches are largely hydraulically operated. The on board hydraulic installations of these cutter dredgers are usually very exhaustive because a lot of specific movements (each with its own requirements) have to be carried out. We have developed product packages to tackle these movements.
