The U. S. Navy has examined the various methods used to design ship hull cathodic protection systems. From fleet experience, the optimal design of Impressed Current Cathodic Protection (ICCP) systems requires the exact placement hull components. Physical scale modeling is being used as a primary tool in determining the placement of anodes and reference cells in order to achieve uniform and protective hull potentials. A one/ninty-sixth scale hull model m linear scaled resistivity electrolyte was used to provide important information on interzone relationships, geometric factors and qalvanic influences. Results from scale models are compared with full scale ship potential measurements and additional fleet comparisons are underway.
