Abstract
Valuable materials, such as manganese, are extracted from the sea bed by pelling through the sea a buoyant body which floats on the sea and carries equipment for extracting the material from the sea bed. A pier connected to the body affords moorings for transport ships which receive the extracted material and conveyor devices associated with the pier deliver the material directly into the ships. The transport ship or ships provide part of the propulsion force for the buoyant body.
