COST COMPARISONS FOR LOCK WALL DEICING

Lock wall icing conditions on the Great Lakes and St. Lawrence Seaway are described, and possible solutions are listed. Operating assumptions are laid down as a basis for consistent cost estimates, and selected deicing methods are considered, using figures condensed from a more detailed report. The estimates cover wall heating by embedded electrical cables and embedded fluid circulation systems, repetitive surface coating with salt solutions, deicing with an inflatable boot, scraping with backhoes, cutting with large chain saws, and slicing with high pressure water jets.
