OPTIMUM CARGO MOVEMENT TO RESTRICTED-ACCESS PORTS

Water movement of cargo to ports with restricted depth of water, channel width, etc., automatically appears to dictate the use of small vessels whose dimensions are tailored to the restrictions. Several designs are suggested which permit a substantial increase in the cargo carried per trip, from which a corresponding reduction in cost per ton of cargo moved may be realized. The designs suggested include: 1) A large vessel designed to carry barges by floating them in and out of the vessel through either bow or stern doors. 2) A manned vessel, sized to suit the port restrictions, push-towing an unmanned barge. 3) A vessel with beam sized to suit lock restrictions, capable of being separated into two sections along the centerline. The trade route considered for design purposes is iron ore from the upper Great Lakes to an unloading dock at the head of the Cuyahoga River navigable channel in Cleveland, Ohio.
