An AC study and mitigation design was performed and installed to address corrosion risks. After a few years of operation, the site was revisited due to changing conditions and increasing AC current densities. For the second evaluation, new modeling software was used to evaluate the risk. This paper is a case study comparing the two modeling software techniques, and evaluation on the impact of the field data quality, and a lesson learned on addressing AC corrosion risk.
