摘要：Dredging or suction of a soil suspension from the sea bottom is effectedthrough a suction conduit connected with a suction head enclosure resting on the seabottom, there concurrently being supplied to the suction head enclosure and through aseparate conduit connected therewith a transport fluid under pressure. Transport fluid isseparated from the soil suspension collected at the surface and recycled to the suctionhead enclosure. Thus the transport fluid flows in a substantially closed recirculating flowcourse and consequently pollution of the sea is lessened.
