Introduction

Cathodic protection is a method for protecting and controlling the corrosion of a metal surface underwater or beneath the ground by making it the cathode in an electrolytic cell. This can be achieved either through the use of sacrificial anodes or by using impressed current anodes.

Cathodic protection is a very specialised field offering well-paid careers in both off and onshore vacancies, either through an employer or as a self-employed worker. This interesting field of work provides genuine career progression and can result in employment opportunities to take you all around the world surveying pipelines and structures.
