ABSTRACT:
An underwater mining or dredging apparatus having a supporting vessel and a continuous loop to which is attached a number of containers. In one embodiment, the loop is hollow and has a ballasted fluid in a lower portion while the descending portion is buoyant. This will reduce the likelihood of entanglement of the loop. In another embodiment, a weight sled is used to help gather the underwater aggregates and prevent wear of the loop. The loop may be designed to hydrodynamically resist entanglements and may be disposed laterally relative to the supporting vessel.
