Marine ship undergoes corrosion in various aspects. Impressed current cathodic protection system (ICCP) is considered to be an optimum solution for corrosion suppression.
The electrical potential is monitored by reference electrodes which are fitted at both port side and starboard side between the anodes and been reflected to the power supply unit. Thus the whole CP system could automatically defects the electrical potential at the hull/seawater interface and raises or lowers the output to the anodes accordingly. This way, the ship receives optimum level of protection against corrosion.
