Navigation locks were identified where extensive damages occur to the locks and the lock gates as a result of vessel collision. Data were collected from several sources in an attempt to qualify all damages resulting from accidents at locks including repair to the lock structure, losses due to delays, and damage to cargo and vessel. The study findings include the costs to repair 80 locks damaged by vessel impact. The statistics regarding repair costs in this report are based on data obtained from seven US Army Corps of Engineer District offices for the period from 1977 to 1987. The survey includes locks on the Upper Mississippi and Ohio Rivers and their navigable tributaries such as the Tennessee, Illinois, and Monongahela Rivers. Analyses of data bases to obtain quantitive delay and vessel damages were inconclusive. Keywords: Boat/ship accidents; Damage assessment; Locks/waterways; Cost analysis/effectiveness; Surface navigation; Impact barriers/collisions. (MM)
