ABSTRACT:
A system for collecting mineral resources on the ocean floor, having an automotive collector for collecting mineral resources, a collection vessel which is connected to the automotive collector so that the collected mineral resources are fed to the collection vessel, and an endless bucket lift device having a number of buckets. The endless bucket lift is lowered from a ship and circulates between the ship and the collection vessel. The circulation of the buckets carries the mineral deposits, collected at the collection vessel, to the ship. The ship has an expansion apparatus having at least a pair of end-rollers on which an endless belt carrying a number of buckets are wound. The distance between the end rollers is adjustable so that the lowering distance of the collection vessel and the automotive collector can be adjusted according to the depth of the seabed.
