Zusammenfassung:	A dredger system (100) for collecting material (112) from a sea floor (110), comprising a dredging vessel (102) with a hopper (116) for storing the material (112), and a suction tube (118) which at a first tube end (122) is arranged for discharging the material (112) into the hopper (116), the suction tube (118) having a second tube end (124) for receiving the material (112). The dredger system (100) comprises a remotely operable dredging vehicle (130) with a suction head (132) and a riser (134) that is at a first riser end (136) connected to the suction head (132). During use, the remotely operable dredging vehicle (130) is situated on the sea floor (110), and a second riser end (138) of the riser (134) is releasably connected to the second tube end (124), for guiding the material (112) from the bottom surface (110) to the hopper (116).
