Abstract

Parametric studies of a shipboard impressed current cathodic protection system using a boundary element code Y. wang', D.

A Canadian naval vessel ICCP system was chosen as a prototype for this study. A variety of factors were taken into account in this study, including the locations of reference electrodes, paint damage and paint degradation, conductivity of seawater, and polarization curve data of the propeller and ship hull materials. A boundary element code developed at DRDC Atlantic was used for the analysis. The studies performed provide an increased understanding of the performance of the shipboard ICCP system under various conditions. 1 Introduction Coatings and impressed current cathodic
