Beaver® in short

Beaver® CSDs are reliable, fuel efficient, have low maintenance costs and are extremely productive at all dredging depths. We have a proven track record of 60 years, with almost 1,000 of these cutter suction dredgers supplied worldwide since 1963.

Over the years, the design of our Beaver® is continuously improved using the latest technological developments and feedback from our customers. Innovations and digital solutions are added - such as electrification and operations monitoring solutions - which improves operational efficiency and a sustainable performance. 

These dredgers are capable of dredging compacted soil types and materials, such as clay and rock. High accuracy and a continuous rate of production ensure that our Beaver® vessels are ideal for many dredging jobs, such as land reclamation and the construction of new harbour basins and canals.  

Why choose a Beaver® dredger
  • reliability due to high maximum uptime and high performance
  • lifetime product support with unique dredging expertise at any moment of production
  • short delivery time, available from stock 
  • opportunity of customer financing 
  • best value for money, lowest cost per m3.

Find the right Beaver® for your project

To help you select the right Beaver® for your project, a first selection can be made based on the pumping capacity of the dredger. The output of the various Beaver® dredgers for medium fine sand (235μm 1,950kg/m3) is shown in the graph. This can be matched with the required output and distance to be pumped. The graphs are based on output expressed in cubic meters of in-situ solids per effective pump hour and elevation at the end of the pipeline of 4 metres.

Output based on free-flowing material

The calculated output curves only indicate the pumping capacity, based on free-flowing material. In practice soil properties may vary from free-flowing to hard-to-excavate material. The nature of the material to be dredged and the project conditions should be taken into account when using the curves to estimate actual outputs.



What is the price of a Beaver®?

The price will vary due to local regulations, transport requirements and insurance, amongst other things. Please feel free to contact us for a more detailed price indication. 

Do you supply spare parts?

We can supply you with all the spare parts you need for the systems installed on your vessel and take care of the necessary logistics. Through our global stocking locations, we can supply spare parts whenever you need them, allowing you to maintain your systems efficiently and economically.

An optional Beaver kit is available for all of our Beavers®. This kit contains all the critical spare parts you need for the initial stages of your operation.

What is the delivery time?

Royal IHC has stock at all times. Please contact us for the most up-to-date information on current stock levels.

Can Royal IHC help me with the financing of my dredging equipment?

Our experienced and knowledgeable financing team liaises with you and lenders to create a suitable financing structure, managing any potential risks. Financing institutions have separate funds to invest in sustainable ‘green’ solutions and financing is done against a lower interest rate than brown solutions. This in turn lowers the cost for asset owners.
