Clever solution automating the current ouput
The systems are designed to automate the current output while the voltage output is varied. This allows the protection level to be maintained as the seawater resistivity alters. In a sacrificial anode system, increases in the seawater resistivity can cause a decrease in the anode output and a decrease in the amount of protection provided. With ICCP systems protection does not decrease in the range of standard seawater.
An essential feature of ICCP systems is that they constantly monitor the electrical potential at the seawater/hull interface and carefully adjust the output to the anodes in relation to this. Therefore, the system is much more effective and reliable than sacrificial anode systems where the level of protection is unknown and uncontrollable.
By installing a C-Shield system, operators can make significant savings in hull maintenance costs as well as achieving reductions in fuel costs by having a smooth hull surface. Furthermore, the system will safeguard the owner’s investment and ensure greater safety through stronger hull integrity.
