外加電流陰極防蝕 impressed current cathodic protection ICCP

This allows protection levels to be maintained as seawater resistivity alters. In a sacrificial anode system, increases in seawater resistivity can cause a decrease in the anode output, and in turn in the level of protection offered. With an ICCP system, protection does not decrease across the standard range of seawater encountered.

An essential feature of our Cathelco ICCP systems is that they constantly monitor the electrical potential at the interface between the seawater and the hull, carefully adjusting the output to the anodes in response. Therefore, the system is much more effective and reliable than a sacrificial anode system, where the level of protection is unknown and impossible to control.

By installing a Cathelco C-Shield system, operators can make significant savings in hull maintenance costs and also reduce fuel costs thanks to a smooth hull surface. Furthermore, increased hull integrity safeguards the owner’s investment and increases safety.
