Course Description

Maintaining the ageing infrastructure such as underground pipelines is a challenge to the oil and gas industry worldwide. Understanding why and how cathodic protection works or fails can help the operator formulate appropriate strategy in managing the pipeline corrosion problems. This five-day course covers both the fundamentals and practices in designing, operating and maintaining cathodic protection of underground pipelines. An overview of the NACE standard on “Pipeline External Corrosion Direct Assessment Methodology” will also be presented.

Course Objectives

  • Drawing a simple model of a Cathodic Protection cell and name the different elements 
  • Naming 2 types of Cathodic Protection Systems 
  • Explaining the relationship between Coatings and Cathodic protection 
  • Naming and describing 2 different testing methods used to test Cathodic Protection 
  • Understanding terminology commonly used when discussing Cathodic Protection 

Who Should Attend?

  • Designers and anyone who are interested in cathodic protection technology for corrosion prevent
  • Facility owners and users who are concerned with corrosion
  • Technicians and maintenance personnel
  • Engineers and technologists
