It is proven that cathodic protection eliminates corrosion. The protection is provided by anode amperes. This protection, however, must be provided at optimum ampere levels - too little and corrosion occurs, too much and coatings may be damaged. With ships, the optimum amount of amperes is always changing.
Ampere requirements increase proportionately to ship speed, coating age, and oxygen content.
Current provided by ICCP is automatically and continuously adjusted to meet conditions. Voltage provided by sacrificial zinc or aluminium anodes is too high when new and too low when old.
