The steam coal trade boomed following the doubling of crude oil prices in 1979.This thesis develops a model of the entire export coal
transportation network from the mine at the origin to the utility at the destination, to address the question of idiether and where to dredge. By modeling the entire network, changes in any link can be examined to determine its impact on the network as a idiole. In this study the impact of port dredging is investigated by modeling improvements at Baltimore, Hampton Roads, and Mobile. The result of the study is the clear indication that dredging Baltimore alone is the best option available now at low export
coal volune, and that the benefits of dredging will increase as the volume of export steam coal increases. This solution is
robust in that the changing of rail and vessel costs in a sensitivity analysis does not affect the solution materially. The OS will
still be the high-cost producer, but the dredging of Baltimore
will improve the ability of the US steam coal producers to compete
on the world market. |
