For several decades, the preferred solution for isolating dredging pumps within a vessel has been double-walled pump housing. To bypass this housing type’s intrinsic problems, Damen formulated an alternative.
To promote innovations within the realm of safety within the dredging industry, the International Association of Dredging Companies gives a Safety Award to an exemplary programme, procedure or project each year. Announced at the IADC’s Annual General Meeting, the winner of the Safety Award 2018 is Van Oord’s Debris Removal Platform. Van Oord changed the existing technique of manually removing debris to an automated system, reducing the risk of personal injury.
Trailing suction hopper dredgers can fill their own holds (hoppers) by sucking material from the seabed using a trailing suction head fitted to pipes that trail over the bed as the ship sails.
A one-dimensionalhorizontal modelling tool which accurately predicts the overflow of sediments and bed layer distribution inside the hopper of a Trailing Suction Hopper Dredger is introduced.
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.
