In Japan securing disposal fields to receive soft dredged material is a growing challenge. As a result, research for recycling soft dredged material to solidify it for construction purposes is highly advanced.
Dredging stiff clay is notoriously difficult. A newly patented system using high pressure waterjets in the hopper dredger's draghead has solved several operational problems. For his description of this innovative technique, the author was presented with a 2002 IADC Award at the PIANC Conference in Sydney, Australia.
