WHICH BEAVER® IS RIGHT FOR YOUR PROJECT?

To help you select the right Beaver® for your project, please use these graphs as a guide. A first selection can be made based on the pumping capacity of the dredger. The output of the various Beaver® dredgers for different types of sand is shown in the graphs that follow. This can then be matched with the required output and distance to be pumped. The theoretical output graphs are based on the information as indicated below.

THE GRAPHS ARE BASED ON

output expressed in cubic meters of in-situ solids per effective pump hour

elevation at the end of the pipeline of 4 metres

pump output in m3 of in situ solids per effective pumping hour.

NOTE

The calculated output curves only indicate pumping capacity, based on free-flowing material. In practice soil properties may vary from free-flowing to hard-to- excavate material. When used for estimation actual outputs, the nature of the material to be dredged and project conditions should be considered.

Cutter suction dredgers can be used for a wide range of dredging projects. They reclaim land from the sea, dredge entrance channels, and create or extend harbours by removing soil from land. They are also used to clean up pollution and silt from rivers, lakes and canals.

SERVICES

Once the dredger has been delivered to the customer, IHC provides high-quality services and global support. We help customers to operate their IHC Beaver® in an efficient manner in order to achieve optimum levels of productivity. The services we can offer allow operators to increase the uptime and improve the performance of the vessels and equipment while reducing the total costs of ownership. We help increase uptime

by providing maintenance support, repairs, and all necessary spare parts and logistics.

Our experienced service engineers and dredge masters are available to provide advice to customers and to instruct operators, as well as for analysing the operation and performance of the dredging equipment on site.

of the IHC Beaver®. To further enhance the skills and knowledge needed to operate and maintain the vessel, we provide project-specific, operational and maintenance training. The CSD on-the-job training programme strengthens and consolidates the knowledge and skills of attendees. Operators can put what they learn into practice on a daily basis and improve the overall efficiency of their dredger.

The CSD simulator training course gives operators a unique opportunity to enhance their skills using state-of-the-art dredge simulators and learn how to operate the equipment in a safe environment. For engineers, the IHC Training Institute offers an exclusive Beaver® maintenance training programme that covers all aspects of dredging equipment, such as electric installations and hydraulic systems.
