Impressed Current Cathodic Protection systems are a technique for controlling the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. Impressed Current Cathodic Protection systems are in widespread use at thousands of oil and gas surface production facilities, and serve to prevent failure of piping and other facilities which may lead to uncontrolled release of products, resulting in safety hazards and environmental contamination.

This guide is intended to help those designing, installing, inspecting, or maintaining impressed current cathodic protection systems meet minimum regulatory requirements; and it also simultaneously benefits worker safety and reliability of the system. It outlines, from an electrical perspective, design and installation criteria related to impressed current cathodic protection systems, including:

  • codes and standards related to cathodic protection work
  • worker qualification
  • equipment certification
  • connection and splicing methods
  • installations
  • warning signs
  • documentation
  • electrical inspections
