DAMEN Presents Flexible Dredging offshore
The new flexible dredging concept is the answer to increasing demand for raw materials while sand winning locations are located further from shore at increased dredging depths. The RoRo Deep Dredge, which can work up to -200 m dredging depth, has specifically been designed to meet this demand and to challenge current technical limitations. Shortage 
Sand Mining Sand Mining Effects Sand Drenching
Suction dredging [aka Sand Mining] is akin to open-cast mining, where the entire top surface of the seabed is removed to depths of up to 20 metres. Every living thing in the sand is killed in the process, turning both the mined areas plus a significant area around the mining sites, into a dead-zone.
