The cargo carrier is comprised of a plurality of longitudinal frame members connected by a plurality of cross members with decking affixed thereto to form a horizontal carrier bed. The bed is of sufficient size to accommodate the placement of at least ten, but preferably 14 sling loads of break bulk goods thereon with the allowance for a perimeter work area. A gooseneck portion with tractor attachment means is supported by a first end of the bed and a plurality of wheel assemblies are mounted at the opposite end of the bed. The method comprises positioning the cargo carrier in the debarkation area beneath an unloading position of the ship's crane. At least ten sling loads of break bulk goods are transferred from the ship to the cargo carrier in a single operation.
