    Abstract: A refurbishing system for refurbishing a barge includes transport systems that pull the barge out of water and onto a shelf above water level, then pull the barge into a covered blast system and a covered coating system. A reclamation system receives spent abrasive media. The transport systems then move the refurbished barge back into the water. The transport systems move the barge without substantially tilting it or changing its orientation.
