REPAIR PROCEDURES. Repair techniques for waterfront steel
structures are summarized in Table 8-1. Selecting a technique must address
both immediate repairs necessary to restore the structure to full (or other
designated) usage and protective measures needed to prevent further corrosion.
Selecting a means for restoring the structural capacity of the facility may be
straightforward, being generally controlled by the level and rate of deterioration.
Decisions on the level of protection needed to inhibit future corrosion may be
more difficult. Generally, these decisions are economically driven.
Each repair decision must carefully weigh the long-term operational
requirements and existing environmental factors (tides and currents) that can
help accelerate corrosion before evaluating initial and life cycle costs. In many
cases, combining cathodic protection and protective coating in the repair decision
may be the most cost effective in the long term. Using any of the repair
techniques that follow should fully adhere to the preservation treatment
requirements outlined for steel structures in Chapter 3.
Damaged steel hardware such as cleats and bollards in general
should be replaced in kind. Care should be taken that the engineer determine the
cause of failure and that the replacement item conforms to NAVFAC Standard
