INTEGRATED TUG-BARGE UNITS FOR OCEAN TRANSPORTATION

In the past decade, great emphasis has been laid on providing low cost marine transportation of bulk commodities and other cargoes between the sea ports of the United States. This effort, by barge operators and designers alike, has produced barges of ever increasing dimension and capacity propelled by tugs of ever increasing horsepower. With this increase of size, designers have concentrated on new devices for barge pushing, rather than towing on a line, in order to provide greater overall efficiency of the tug-barge combination and faster service speeds. The methods adopted to connect the tug to the barge stern vary considerably in complexity and cost, ranging from relatively simple cable connections to sophisticated hydraulic and mechanical devices. Of particular interest in coastwise and ocean barging operations is the deep stern notch concept whereby the tug is partially surrounded by the barge stern structure. Deep notch systems that hold the tug rigidly within the barge stern allowing no relative movement between tug and barge have been developed, tested, constructed and operated. Since this fully integrated combination shows promise in providing a fast, ocean-going barge transportation system, this paper concentrates on this type.
