Abstract
A comprehensive program was conducted to develop two independent methodologies of generating hull potential profiles for impressed current cathodic protection systems (ICCP). The two methodologies developed were physical scale modelling (PSM) and computer simulations using CPBEM and BEASY boundary element software suites. A 1/100 scale model of the Canadian Patrol Frigate (CPF) was fabricated and instrumented for comparison with the computer simulations. The results indicate that both CPBEM and BEASY computer simulations were in good agreement with the potentials generated by the PSM/ICCP model. For the quiescent tests conducted, the potentials predicted by CPBEM and BEASY were generally within 15 millivolts and 35 millivolts of the PSM potentials, respectively. For the dynamic tests conducted, both CPBEM and BEASY prodced potentials within 35 millivolts of the PSM potentials.
