Usually ship-form in design, a hopper dredger deposits the dredged material in an on-board hopper for transportation.A method for dredging using a hopper suction dredger comprises sucking up the material for dredging with the aid of the suction installation of the hopper suction dredger, feeding the sucked-up dredged material to at least the well of another vessel, sailing the other vessel from the location where the dredged material has been sucked up to a location for discharging said material, and the subsequent discharging of the dredged material from the other vessel at the discharge site. A hopper dredger with a propulsion system enabling it to be autonomous in its movements has the technical characteristics necessary for navigation allowing it to carry out such a provision of services.
