Cathodic Protection

EPCM designs, monitors, constructs, tests, and maintains Cathodic Protection Systems. These systems protect assets such as cross-country pipelines, buried plant piping, storage tanks, pressure vessels, and marine infrastructure from costly corrosion damages.

Cathodic Protection (CP) is an electrochemical process where Direct Current (DC) is applied to a metal to slow or stop corrosion currents. When properly used, CP stops the corrosion reaction from occurring.

Our team has extensive experience along the complete value chain of CP systems on successful projects in some of the most remote and harshest conditions.
