Product Description

A Cutter Suction Dredger (CSD) is an efficient structure for precise dredging in hard soils and shallow water. It is usually kept on position with a spud pole and the dredging is performed by a rotating Cutter Head at the end of a hinged ladder which is lowered to the seabed. The CSD`s rigid spud system is capable to keep the cutter accurately in the breach, even in hard soils. A disadvantage of the spud is that it makes the CSD a mass spring system in the horizontal plane, with natural periods within the wave period regime. Large dynamic spud reactions are the consequence. When the cutter is in the breach, pitch motions cause the cutter to pound into it, leading to problems like slack ladder hoist wire, stalling cutter drive and even damage of teeth or blades. On top of that, handling of the swing wire anchors, auxiliary boat operations and floating discharge line will put other restrictions on the operability of the CSD.
