Reference Answer
### Introduction to Impressed Current Cathodic Protection (ICCP)
Impressed Current Cathodic Protection (ICCP) is an electrochemical method used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A DC power source supplies a current through non-consumable anodes to the submerged hull surface, which suppresses the natural corrosion process. New developments focus on providing more precise, adaptive, and efficient protection, addressing the complex and dynamic marine environment.
