ONE THOUSAND FOOT GREAT LAKES SELF-UNLOADER

The "JAMES R. BARKER" is the first of two self-unloading bulk carriers designed and built by the AMSHIP Division of the American Ship Building Company for operation by The Interlake Steamship Company, Cleveland, Ohio. The original design concept contemplated by The Interlake Steamship Company predicted a vessel one thousand feet long, capable of carrying fifty-eight thousand long tons of taconite pellets and approximately fifty-two thousand short tons of coal, and be capable of being loaded at ports such as Taconite Harbor, Minnesota and Superior Coal Terminal, Superior, Wisconsin. The design included a flat tank top, a cargo reclaiming machine and a forward deckhouse; however, early design study and cost analysis dictated moving the forward deckhouse aft and modifying the cargo hold configuration to include a three-belt unloading system with hopper slopes.
