Unloading a 300 meter coal bulk ship akxc

Good afternoon, here in Porto de Shark ore is loaded every day, also here in Praia Mole coal is unloaded every day, the view is impressive, this port area is another world.There must be a more efficient way to do this, like a slurry system where the coal is mixed with water so it flows smoothly. Not only are the buckets slow and cumbersome, but they are expensive and wear out, as does the crane(s), and they use a lot of electricity. A slurry system, which is used in similar applications, uses a source of water into the hold, and a large suction tube which carries the coal to the storage area. Does anybody know if this is feasible?
