As Bob said custom discharge conveyor so can more easily collect output. Btw bulk cargoes from China TO North America are reportedly relatively rare so for the return voyages Bao would possibly have to find bulk cargo elsewhere in Asia for return ship to North America-preferably one that can be repeated on a regular basis. This problem of maximizing ship both ways is probably 1 of the most difficult things about shipping-especially when dealing w long distances like the 5647 nautical miles from CWRN to the most commonly used (Quindao) Chinese port.
