Ft. Madison Bridge Study - Effects of Current, Horsepower and Alternate Channel Configuration on Navigation through the Atchison-Topeka and Santa Fe R.R. and Highway Bridge, Ft. Madison

摘要

This report describes the preparation and conduct of a simulator experiment in River Tow Navigation through the Atchinson Topeka and Santa Fe R.R. Bridge at Fort Madison, Iowa using the Coast Guard Maneuvering Simulator. Detailed qualitative and quantitative results obtained from the simulations are presented and analyzed. The study was designed to determine the effects of different levels of current, horsepower, and alternate channel design as well as pilot performance on safety at the bridge. This study was initiated by the Second Coast Guard District due to concern because of number of accidents at the Ft. Madison Bridge. Conclusions of the study include (1) The Fort Madison Bridge does pose an unacceptable risk to experienced pilots; (2) High flow and design of the channel have a margin impact on operational safety; (3) The Navigation span opening of the bridge is inadequate.
