  • Vessel loading method
    Patent number: 4483655
    Abstract: A large cargo vessel is loaded by moving a self-unloading barge alongside and fixing it relative to the vessel. A boom assembly of the barge is slewed into alignment with a hold of the vessel whereupon a shuttle conveyor is extended over the open hold. Bulk material is then unloaded from the barge to the vessel. The boom assembly can be incrementally slewed, luffed, extended and retracted to position cargo in the hold. And, the barge can be repositioned next to the ship without assistance of a tug.
