A system including devices and methods for transporting or storing materials uses slidable containers, or modules. The modules have recessed wheels that facilitate sliding movement when placed on tracks. The use of tracks allows for precise placement of the modules in close proximity to each other and the walls of a vessel or facility they are placed in. The modules may be disassembled for easy, compact storage or transport. The modules may be used with a lift platform adapted to accommodate the modules and tracks or rails for engaging the recessed wheels. By using closely aligned tracks, the transport module may be used to maximize efficient use of space when transporting cargo.
