IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM (ICCP)


Cathodic protection is a method that has been used since the early 1800s to prevent the corrosion of maritime structures such as ships. Electrochemical corrosion can be prevented if the potential, or voltage, on a metal is altered past a certain value. Impressed Current Cathodic Protection (ICCP) systems operate with anode current which is supplied by a power supply rather than by a sacrificial metal. Because the system now actively controls the corrosion, anodes can be made from noble metals to minimize deterioration, fewer anodes are required because of the increased output capabilities, and feedback control can be included to closely monitor the hull protection levels.

This is the reason why the best corrosion protection for an underwater hull is an impressed current cathodic system. ICCP system consists of nonsacrificial noble anodes connected to power supplies, reference cells to monitor hull potential state, and a controller to adjust the current output of the anodes. Anodes must be located so that the current distribution can be uniformly maintained at all points along the underwater hull.



Advantages

Technical

• Always the right level of protection, as the system compensates for the coating-damage.
• ICCP anodes are flush-mounted in the hull which makes them less vulnerable.
• Hull protection can be monitored and checked whenever required or wanted.
• The option to monitor the condition and protection levels through Internet (MME Xchange™).
• Automatic operation, requires minimal attention and demands very little crew time.

Commercial

• Reduced maintenance costs as the system provides a life time protection.
• Extended docking intervals.
• Fuel savings/ higher speed, better hydro dynamic performance.
• Competitive prices.
• Several ranges to suit vessels of every sizes
