Damen Dredging Equipment has developed an innovative flexible dredging concept which challenges current technical limitations. The new development is the answer to the increasing demand for raw materials while sand winning locations are located further from shore at increased dredging depths. The RoRo Deep Dredge, as the innovative solution is called, can work up to -200 m dredging depth.

Two vital aspects of the RoRo Deep Dredge installation are the key to its flexibility. First of all the dredging equipment is placed on a Platform Supply Vessel – thus the storage and transport facility of the mined sand has been separated and is done by a number of barges. Secondly, the steel suction pipes of TSHD’s have been replaced by a flexible hose. Hence the dredging depth can vary and has become independent from the vessels length.
