Abstract
A marine loading/unloading system for barges, etc. including a floating transfer vessel of catamaran configuration into and through which strings and tiers of barges and large single barges, empty and loaded with liquid or solid bulk product, are moved and positioned for loading and unloading. The barges are moved and controlled externally by means of moorings on endless cables running to anchor barges situated at appropriate locations upstream and downstream of the transfer vessel; and controlled internally by wheel systems positioned on the internal vertical hulls which alternatively (FIGS. 7A vs. 7B) control the movement of the barges during vertical and horizontal, lateral or longitudinal movements. The bulk product, solid or liquid, is loaded and unloaded through hopper and tank systems in the horizontal, upper bridging hull or structure, from and into vessels or ships, and from and into pipelines and other vessels through processing equipment located in the transfer vessel. A lower, below the water-line bridging structure (FIG. 10) can be included for strength and greater buoyancy. For bulk products such as coal, grain, etc. an internal dust or loose particle collection and s…
