NEW PROCESSES OF UNLOADING TRAILING SUCTION HOPPER DREDGERS

Self-propelled hopper suction dredgers are generally so arranged that they can either 'dump' the spoil through bottom doors or discharge it through connected pipe lines by means of the centrifugal pumps installed on board. The latter operation increasingly gains importance, as the spoil to be discharged can often be used to advantage in the reclamation of new, valuable land for the settlement of industry and residential areas. The economics of the discharge of solids from hopper suction dredgers, however, leave much to be desired. Therefore, an improved method of discharging solids is introduced here, supported by comparative model and full-scale tests demonstrating its superiority compared with the conventional method of discharge.
