A comprehensive program was conducted to develop two independent methodologies for generating hull potential profiles for impressed current cathodic protection systems. The two methodologies developed were physical scale modeling and computer simulations using CPBEM and BEASY software suites. Conducting the physical scale modeling trials required upgrading the previously inactive PSM facility. The upgrades included designing and development a digital communication protocol for the system, controllers for the PSM analog devices and controllers for the ICCP model. A 1/100 scale model of CPF was fabricated and instrumented for comparison with the computer simulations. The results indicated 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 5 percent and 2 percent of the PSM potentials, respectively. For the dynamic tests conducted, both CPBEM and BEASY produced potentials within 5 percent of the PSM potentials.
