Ships are often exposed to very harsh marine environments. Due to the environment in which they operate, the ship’s hull is often vulnerable to environmental corrosion. SACP is applied to ships to protect the immersed sections of the vessel from corrosion.
The antifoulants (ions) released by the copper and aluminium anodes in small concentrations create an environment that mitigates corrosion and discourages organisms to adhere and breed.
By pairing reference electrodes with disc-shaped anodes mounted below the water line, the whole CP system is designed to continuously monitor the level of protection and automatically adapt to the current required to avoid corrosion.
