Repairs and Overhauls

Direct CP is proficient in testing and maintaining CP systems. We can repair or upgrade your old perhaps unreliable or out of spec. equipment and install new state of the art products to give you the best assurance that your assets are protected 24/7.

Contrary to popular belief, most CP systems are not fit and forget installations.  Defective or inadequate Cathodic Protection systems cost global industry many billions of dollars annually and is largely avoidable.  Sacrificial Anode CP systems are often more stable and reliable than their bigger Impressed Current cousins however both systems can be rendered ineffective by the simplest of things.

CP systems can and do fail for a multitude of reasons, for example an isolation failure can incorporate additional steel into the CP system causing an extra drain on the CP equipment and not leaving enough current to adequately protect the primary structure.  An inadvertent connection to a copper earth system will usually be catastrophic to protection levels.

Anti corrosion coatings degrade over time causing the structure to require more protective current from the CP system.

Increased current output from Transformer Rectifier Units can increase the propensity for very destructive dc interference  to adjacent buried metallic structures.

Minor events can and do cause CP systems to become ineffective and if not identified allow irreversible corrosion to occur.

Talk to us about how we can assist you in keeping your CP system effective, your assets protected and reducing your costs.
