The modeling of corrosion protection systems in seawater is classically based on boundary element method (BEM) and is generally limited to static studies. This article presents an original transient approach coupling a BEM for the modeling of the seawater and a circuit representation approach in order to introduce nonlinear polarization laws and impressed current cathodic protection (ICCP) electric system. A special care is taken to the numerical implementation enabling the modeling of complex systems and interface phenomena.
