Abstract

This paper is concerned with the application of the Boundary Element Method to cathodic protection problems of submerged structures using polarization curves depending upon time and formation potential. These curves have been adjusted from potentiostatic data obtained from in-situ experiments, yielding a nonlinear functional representation. The solution technique adopts stepwise linearized polarization curves and is employed for sufficiently small time steps. The influence of varying formation potential is introduced into the analysis under two alternative hypotheses here designated fictitious time and fictitious potential.
