Abstract:

This study is phase 2, part B of the Great Lakes-St. Lawrence Seaway Navigation System Study. Objectives were twofold 1 to estimate total transit time for ships navigating the Great Lakes-St. Lawrence Seaway system during a winter season and translate these times into vessel operating costs and annual freight rates for major commodity routes, and 2 to estimate effect on these annual freight rates of improvement levels, length of navigation season, winter severity, and vessel fleet mix. A computer model of Great Lakes-St. Lawrence Seaway was developed. It was concluded that all-year navigation on the Great Lakes-St. Lawrence Seaway is commercially feasible. Annual freight rates would decrease for laker bulk cargo routes, but increase for overseas routes. Ships which would benefit most from season extension would be the larger, more powerful and more economical ships. Contractor recommends that the overall Great Lakes-St. Lawrence Seaway system model planned for Phase 3 of this study be developed.
