Cathelco Ltd. offer a choice of modular or thyristor (SCR) control panels Impressed Current Cathodic Protection (ICCP) Systems for Marine Semi-Submersibles. Thyristor panels can be used on systems of up to 1000 amps and combine cost effectiveness with rugged reliability. Modular panels can be used on systems of up to 350 amps and have the advantage of being lightweight and compact. Both types of panels incorporate computerized output displays, alarms and information systems

ICCP Reference Electrodes

Reference electrodes measure the electrical potential at the hull/seawater interface and feed a signal back to the control panel. They have zinc elements and are ‘diver changeable’ enabling them to be replaced from the outside of the hull by a diver.

ICCP Anodes

A range of anode designs are available for offshore applications. These include rod anodes, flush mounted disc anodes and linear loop anodes which emit a powerful current from a relatively small surface area. All of the anodes are ‘diver changeable’, simplifying replacement.
