The Netherlands: IADC Presents Facts About Dredging Plant and Equipment

IADC Presents Facts About Dredging Plant and Equipment

Dredging equipment is quite varied. From large to small, from simple to quite complex. The question often arises, what is the difference? Why choose one type of dredger over another? Is availability the only criterion? Or are there more reasons to choose a specific dredger? How does one balance cost efficiency and environmental concerns?

This executive summary gives an overview of the types of equipment most commonly used for dredging projects and what each type of plant has to offer. It distinguishes between mechanical, hydraulic and hydraulic/mechanical dredgers, with Trailing Suction Hopper Dredgers (TSHDs), Cutter Suction Dredgers (CSDs) and Backhoe Dredgers (BHDs) being the most typical workhorses of the industry at the moment.

Each of these “workhorses” has its own advantages and disadvantages that can only be determined by studying a particular project – because each dredging project has its own unique demands. The cost-efficiency of a project is determined by matching the site-specific conditions with the characteristics of the equipment.

A particular project is influenced by the quantity and type of soil or rock that is present, where it is located and where it may have to be relocated or placed. Weather conditions and the accessibility of the site, such as its depth or width, and environmental issues such as marine habitats, their flora and fauna and contamination must be considered.

No single type of dredger is suited for every project. IADC’s overview will give decision-makers a first insight into matching the proper dredging equipment to the dredging operation they may be facing, be it coastal replenishment, port maintenance or land reclamation.
