Computational Modeling of Coating Integrity Effects on Impressed Current Cathodic Protection System.

Abstract

Coatings are often used in conjunction with impressed current cathodic protection (ICCP) systems to minimize the effect of corrosion on marine structures. The presence of a coating reduces the current required by an ICCP system. The integrity and efficiency of the coating determines the level of current reduction achieved over the bare metal condition. One of the difficulties is designing a combined coating and ICCP system is that coatings deteriorate with time in service due to a variety of factors including mechanical wear and organic attack. In this study computational modeling is used to determine the variation in current demand required for corrosion protection for increased levels of damage to the protective coating applied to the propellers of a surface ship. jg
