General information
Rock dumping vessels transport and dump rocks of various sizes for offshore and coastal protection applications. The dumping can be done with a large crane, but also through the concepts of side stone dumping vessels and flexible fallpipe vessels.
Side stone dumping vessels sail to their destination, where shovels put the rock overboard at a steady pace. This rock dumping method is typically used in shallow water. Flexible fallpipe vessels are used in deep water, bringing the large amounts of rock in their holds. The rocks are dumped through a long and flexible fallpipe and a Remotely Operated Vehicle (ROV) makes sure the accurate dumping of the rocks.

Services & Activities
The Offshore Department has developed the DREDSIM simulation program to simulate the behaviour of Stone dumping vessels in waves. It allows the analysis of the motions of the vessel and their fall-pipe. Also the Dynamic Positioning capabilities can be analysed. This is all combined with a downtime analysis in a certain environment.
The Seakeeping Department can assist in the determination of the seakeeping behaviour while on transit, whereas the Manoeuvring Department can assist in the analysis of the manoeuvrability in shallow water and the Dynamic Tracking capabilities. Resistance and Powering can be assessed by the Ships Powering Department. The Trials & Monitoring Department is involved in full-scale measurements of ship performances.
