Monitoring of settling and consolidation of mud after water injection dredging in the Calandkanaal

As regular maintenance and relocation of sediment deposits are highly expensive, Port authorities seek more efficient solutions for reducing the costs and CO2 emissions of maintenance dredging. One solution, water injection dredging (WID), is carried out for maintaining the sediment deposits which predominantly consist of clay and silt. WID has been proven to be a cheaper solution by leaving the sediment in place, eliminating substantial costs for relocation of the dredged sediment.

A Guide to Cost Standards for Dredging Equipment 2009

A joint venture between IADC and CIRIA, the publication A guide to cost standards for dredging equipment 2009 offers a benchmark to establish the capital and related costs of various types of dredging plant and equipment commonly in use within the industry.

Dredging Plant and Equipment

“Facts About Dredging Plant and Equipment” describes the specialised equipment that has been developed to perform various and specific dredging operations.

Water Injection Dredgers

A water injection dredger injects large volumes of water into the waterbed, fluidising the sediment so that it can flow naturally to other deeper areas.
