How can you be sure that your vessel’s cathodic protection system is working properly?
Whether you have a sacrificial anode or an impressed current system it is important to know whether it is functioning effectively to prevent hull corrosion.The Cathelco Portable Corrosion Monitoring System is an essential piece of equipment for ship’s crew.
It provides a means of testing the electrical activity in seawater surrounding the hull (which causes corrosion) and a way of measuring it against a recommended standard. Inadvertent connections to an un-isolated shore grounding can be easily detected, enabling action to be taken to avoid galvanic corrosion.
Readings can be made when a vessel returns to moorings to ensure that there is no drain on the cathodic protection system from other vessels or via jetties and piers as the resulting of a grounding fault from the AC shore supply.
Using the system regularly avoids the risk of unknown corrosion activity and the costs associated with unplanned haul-out.
