Master's thesis of Civil Engineering: An investigation into impressed current cathodic protection systems in Australian wharves

This study examined the phenomenon of residual protection by suspending the operation of established ICCP systems in two wharves located in southern Victoria and monitoring the effect on the passivity of the steel via electrochemical testing. The results of the study confirm that the steel in selected elements within these structures remained passive once the ICCP system was interrupted. The primary factor in determining which elements remained passive, and the duration of passivity was the amount of charge injected into the element over the life of the ICCP system.
