Abstract

A dredging apparatus comprises a submersible pump (13), mounted on a crane jib (12). The pump carries an emulsion of water and solids to the surface and passes it through a liquidiser unit (90) to reduce the particle size. A velocity reduction unit (71) lowers the particle velocity and then ejects the emulsion into an ebbing body of water (60) which carries the solids out to sea.
