How ICCP works
ICCP systems use an external power source to deliver a controlled protective current to submerged steel surfaces. With long-life anodes Cathwell ICCP system can protect vessels and offshore units of any size and all operating conditions.
The key feature of ICCP is its ability to continuously monitor and adjust protection levels. Sensors measure the electrochemical environment around the hull, and the system automatically adapts to changes in coating condition and operating environment.
