Cathelco are technological leaders in ICCP hull corrosion protection systems for ships and offshore platforms. The systems consist of an arrangement of hull mounted anodes and reference electrodes wired to a control panel.
A range of C-Max anodes is available in disc and linear form which have the advantage of being lightweight and diver changeable.
The latest Quantum ICCP systems provide greater connectivity with control panels which enable data to be relayed to control room or the bridge via an RS485 link.
In operation the reference electrodes measure the electrical potential at the hull/seawater interface and send a signal to the control panel which automatically raises or lowers the output to the anodes. In this way, the hull receives the optimum protection against corrosion at all times.
Systems can be provided for ships of every size ranging ranging from offshore supply vessels and product carriers to FPSOs which remain at sea for prolonged intervals without drydocking.
Cathelco's engineers have amassed expertise in the design of ICCP systems to protect oil and gas platforms operating in locations as far apart as the Gulf of Mexico and the Russian Arctic. The systems are designed to provide effective protection for large and complex structures which will inevitably suffer coating loss during their time in operation. For Arctic conditions Cathelco provide specially designed ice class anodes and reference electrodes to withstand the pressure of winter ice, together with thyristor pannels which provide outstanding reliability.
