Transportation of Iron Ore, Limestone, and Bituminous Coal on the Great Lakes Waterway System, With Projections to 1995.
This study provides data on the physical and hydrological makeup of the Great Lakes Waterway System and forecasts quantities, traffic patterns, and shipping cost of prospective bulk mineral commerce projected to be transported upon it. Factors affecting the shipping cost of iron ore, bituminous coal, and limestone were quantified and integrated into a computer program that can be used to estimate costs under varying sets of conditions. Combined shipments of iron ore, bituminous coal, and limestone in 1995 were estimated at 276.5 million tons. The cost of operating the U.S. vessel fleet for transporting an indicated 80 percent of this traffic tonnage was projected to be $163.5 million. (Out of print.)
