In what type of environment is ICCP particularly utilized?

The most suitable environment for impressed current cathodic protection (ICCP) is marine environments. ICCP systems are designed to provide consistent and adequate protection in environments where corrosion can be particularly aggressive, such as seawater environments. In marine settings, the presence of salts and other corrosive agents increases the conductivity of the water, making ICCP systems effective by delivering a constant protective current to submerged structures like piers, pipelines, and ships.

ICCP is ideal for these applications because it allows for the use of anode systems that can operate at higher currents compared to other cathodic protection methods, such as galvanic anodes. This ability to provide a strong and continuous protective current is crucial in environments where the corrosion rates will otherwise be high due to the conductive nature of seawater.
