Technicians at WRS Marine were involved in the development of Wilson
Walton International’s system of cathodic protection using impressed current
cathodic protection (ICCP).

Developed over many years of practical experience at sea, the latest version of impressed current cathodic protection employs the finest electrical equipment and hull units available.

The impressed current system comprises anodes, reference electrodes and a transformer rectifier controller power unit. Whilst this protects the hull structure, it is also important to protect the exposed propellor shaft and rudder.

The propeller and shaft are grounded to the hull structure with a shaft slip ring to make them electrically common with the hull, and the rudder is also grounded with a flexible cable. With electrical continuity established, these components are protected by the impressed current system.

Service and commissioning
WRS Marine technicians service all types of impressed current systems worldwide.
