A solution technique for cathodic protection with dynamic boundary conditions by the boundary element method

This article is concerned with the application of the Boundary Element Meth od to cathodic protection problems of submerged structures using polarizati on curves depending upon time and formation potential. These curves have be en adjusted from potentiostatic data obtained from in-situ experiments, yie lding a nonlinear functional representation. The solution technique adopts stepwise linearized polarization curves and is employed for sufficiently sm all time steps. The influence of varying formation potential is introduced into the analysis under two alternative hypotheses here designated fictitio us time and fictitious potential.
