Impressed Current Cathodic Protection (ICCP)
ICCP Systems are corrosion control methods which produce a powerful external current to suppress natural electrochemical activity by supplying a controlled amount of DC current to submerged surfaces, using zinc reference anodes and metal oxide anodes. The electrical current is continuously monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it can begin. This is therefore a widely preferred method of Cathodic Protection as it requires little to no maintenance and reduced overall costs as a result, as well as the advantage of a long service life. Once installed and activated, ICCP systems can provide upwards of 30 years corrosion protection to a given structure.
