Dredging (underwater reclamation) is expensive due to the high cost of the equipment required to carry out this work as well as the variability of the solids concentration that is associated with the variable cutting rates. Dredgers are also not able to reclaim all of the tailings and cannot clear the floor down to the contact between the original ground level Subsea Mining Deep Sea Ocean Mining & ,Subsea mining, or deep sea mining, is a method of retrieving minerals from the ocean floor. Deepsea mining operations typically occur at depths of 4500 ft. to 12,000 ft. around areas with metallic nodules, as well as areas with Different Types of Dredgers Used in the Maritime Industry,These can be of different types such as (top) open grab, (top) closed grabs and watertight grabs. Grab dredgers can be of different capacities ranging between 1.0 and 20 m³ whereas the capacity of grab hopper draggers ranges from 100 to about 2,500 m³. Their capacity largely depends upon the crane power.
