Abstract

The invention relates to a method and a device to be used in dredging. Material present on the seabed is dredged by means of a dredging unit, which is suspended from a vessel (1). Material dredged by means of the dredging unit is supplied to a discharge pipe suspended (5) under water from a vessel (1) and coupled to the dredging unit, via which discharge pipe the material is deposited on the bottom of the sea at some distance from the dredging place. The device is provided with a dredging unit comprising a frame (6) which is provided with propulsion means, by which the device can be moved in any desired direction. <IMAGE>
