Title: Marine transport
Claims: What is claimed is: 1. A marine transport system comprising, in combination, a plurality of modular cargo hold units of generally uniform external configuration and dimension over at least the lower portions thereof, a plurality of self-propelled shuttle vessels for moving cargo hold units between a plurality of at least three ports in the system, the system encompassing a route composed of a plurality of substantially serially connected different subroutes each of which is defined between two adjacent ports in the system whereby the system includes at least one port common to two subroutes, each shuttle vessel being configured to mate with at least any one of the hold units and to support the same, each hold unit being sized relative to the shuttle vessels when loaded and mated with any one of the shuttle vessels to consume a substantial fraction of the load-carrying capacity of the shuttle vessel, each vessel including ballasting means for buoyantly raising and lowering the vessel into and out of mating and load transferring relation to a hold unit supported above the vessel at a dock facility in the system, each shuttle vessel being defined and equipped as to propulsive machinery, and crew accommodations, hull form and proportion, and similar features in consideration of the navigational, meteorological, and operational factors pertinent to a particular system subroute in the system to which the shuttle vessel is assigned and on which the vessel is primarily operated whereby each vessel is different from most or all of the other vessels in the system, and a dock facility in each port in the system, each dock facility being cooperatively configured and arranged in cooperation with the vessels assigned to the subroutes common to the port and with the cargo hold units for receiving from and discharging to a shuttle vessel a loaded cargo hold unit and for supporting a received hold unit for the loading and unloading of cargo to and from the hold unit in the absence of a vessel at the dock facility, whereby, in moving a hold unit from one port on one subroute in the system to a second non-adjacent port on another subroute in the system, the hold unit is movable bodily from shuttle vessel to shuttle vessel at each port in the system intermediate the one port and the second port via the dock facilities in the intermediate ports.
