Course Description
Cathodic protection system retrofits become necessary as the pipeline systems age. An important aspect of such retrofitting is the determination of when such action should take place. Assessment of cathodic protection systems on pipelines is normally performed based on potential measurements. As galvanic anodes waste, their size decreases; and this causes a resistance increase and a corresponding decrease in polarization. Anodes’ depletion is time dependent in the model.
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
