Development of large bulk carriers having rapid discharge capabilities is traced from early history on the Great Lakes through and including today's supercarriers, in operation and on order throughout the world. Discharging methods are defined by class and type to reflect unloading capacity and to describe the more common systems of fast unloading in use by today's large self-unloaders. Various systems of discharging cargo are categorized into three groups covering all belt conveyors, mechanically assisted belt conveyors, and other special types. The paper includes analyses, descriptions and sketches of representative vessels. Factors affecting self-unloader designs, such as cubic considerations, trades, cargo flexibility, manning and costs, are dicussed. Also included are future design possibilities and tabular listings of all the belt conveyor vessels in operation or building.
