Fast Sealift Cargo Handling Technology Concept Report
1991
Foltis, Constantine | Gault, Craig
The subject cargo handling system is designed so a ship can handle on cargo throughout (either RO/RO, containers or break bulk), or all three types simultaneously in different holds and/or different decks. The convertibility concept is based on a standard RO/RO ship arrangement, with a hinged ramp to the pier and interior fixed ramps to all levels of the holds, and watertight doors in bulkheads between holds. Additionally, the ship has hatches over all holds, for vertical movement of LO/LO cargos, including containers in cell guides, with all interior tween deck hatches open and all watertight doors closed. All hatches, including main deck hatches, are flush to facilitate movement of RO/RO at all levels. Steel angle container cell guides are fixed to the underside of all tween deck hatch covers. The guides are out of the way in the overhead when the hatches are closed for RO/RO or break bulk operations, and they are automatically deployed when the covers are opened for container loading.
