COOK INLET COAL: ECONOMICS OF MINING AND MARINE SLURRY TRANSPORT. APPENDIX

This report gives a general description of the Beluga coal deposits on Cook Inlet, Alaska, and evaluates mining and transport costs to move the coal to a potential steam-electric plantsite in northern Washington State as a marine slurry. A surface minesite is chosen 15 miles from tidewater, and the coal is mined, washed, slurried, and transported by pipeline to tidewater where it is loaded aboard ship as a settled marine slurry. The coal is carried by ship to northern Washington, reslurried and pumped off the ship to dewatering facilities. Costs for mining, washing, preparation, transport, and dewatering are developed per ton of clean coal and final costs per million British thermal units. Production rates are evaluated to fuel 1,000- and 2,000-Mw plants with 80 percent annual output factor. Slurry pipelines are evaluated for 24- and 20-inch diameters. Ship sizes evaluated are 70,000, 79,000, and 100,000 dead-weight tons.
