We try a new methode with giant contenairs. with a freighter, we carry few giant contenairs ( 120.000m3) and we full with the hulks around. When 5 /6 are full, the freighter carry back to the station. The huge contenairs 240.000m3 are little to big ans better to use the 120.000 for the operation. now freighter can jettison / load / unload in full space so it s fast and huge ore quantity in each travel.
