dredging innovations


The Ro-Ro Deep Dredge, which can work up to a 200 m dredging depth, has been specifically designed to meet demand from this sector and sets out to challenge current technical limitations. A flexible dredging concept which revolutionises dredging in the 21st century, its modular approach will open up the dredging sector through its ability to enable other vessels or contenders to enter the deep sea mining market in a cost-effective way.


damen dredging innovations

The new Damen dredge pump has been developed by the in-house R&D team. It has a highly efficient double-curved impeller that ensures excellent suction.  

Damen designs its own extensive range of dredge pumps. This includes low, medium and high pressure dredge pumps designed to deliver maximum efficiency and minimal wear. Most shaft sealings are performed by mechanical seals.


dredge pumps innovations 

Damen's highly efficient dredge pumps are fitted out with a maintenance and environment-friendly mechanical shaft seal. These special shaft seals do not require grease or gland water, so minimise service downtime. Existing dredge pumps can be retrofitted with this ecologically-sound alternative.


innovations in dredging 

Damen works continuously to improve all its dredging components, and recently a completely new line of drag heads was launched. The design is based on the latest CFX flow prediction software in combination with feedback from many customers. The new drag head has resulted in improved production.



All Damen vessels benefit from knowledge gathered during ongoing research programmes within the Group. Damen works alongside world-renowned research institutes such as Delft University of Technology, Maritime Research Institute Netherlands (MARIN) and the Netherlands Organization of Applied Scientific Research (TNO), as well as other reputable universities and leading maritime companies.
