Cathodic Protection System

Oilserv Limited carries out the Construction and Installation of both Temporary and Impress Current Cathodic Protection Systems as an integral part of its scope of activities. Our Cathodic Protection (CP) technique is used to control the corrosion of pipe surfaces by transforming the anodic sites on metal surfaces to cathodic sites via an electrical current from an alternate source.

This is vital to the maintenance of Pipeline integrity as Corrosion is a leading cause of premature failure in metallic structures. Oilserv’s CP services can extend the service life of pipelines, facilities and equipment by installing Cathodic Protection Systems.

We design, construct, install and commission Cathodic Protection Systems on Oil & Gas Pipelines and Oil & Gas Flowlines, including Oil & Gas Facilities.
