An Introduction to Constructing and Maintaining Cathodic Protection Systems

COURSE NO: T02-009
An Introduction to Constructing and Maintaining Cathodic Protection Systems
Course Highlights

This online engineering PDH course provides an introduction to the principles of cathodic protection for underground and underwater structures. It discusses the physics and chemistry of the corrosion process and how to mitigate the corrosion using techniques to construct and maintain sacrificial anode and impressed current cathodic protection systems.


Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and steel storage tanks; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust.


This 2 PDH online course is intended for professional engineers and construction managers wanting an introduction to the construction and maintenance of cathodic protection systems.
