Abstract

An apparatus for conveying mud from great water depths comprises mud-conveying piping B in which is interposed a suction pump D of a pump unit C including a pump E delivering pressurized sea water via a flexible conduit K to nozzles at a suction head L carried by the piping B. The suction mouthpiece of the head L is in the form of a conical screen of which the tip is directed downwardly. The screen is vibrated vertically, and the vibrations are damped relatively to the piping B by a spring damping part F. <IMAGE>
