Cathodic Protection Training Course


This course is interactive and will be edited as comments, suggestions, questions and answers arise from the students and teachers.
We have four PhD level students who are being mentored and guided in different universities in different countries on different continents as well as many long time experienced and qualified engineers who are working on a vairety of projects all over the world.
The content of all modules is originally drawn from my personal experience and field experimentation backed up by years of research into the theory and application of cathodic protection in field conditions.
Each module is supported by documentation including pictures and data from actual field activities.
The number of references is expanding and we are keeping up with this by using links as well as the traditional references to published papers. Publication on the internet enables universal peer review and scrutiny.
We can supply the instruments needed for this course, but will require payment plus shipping costs prior to dispatch.
We suggest that it would be quicker and cheaper to obtain the instruments locally or use those already available on site.
