The Cathodic Protection Technologist course builds on the technology presented in the Cathodic Protection Technician course with a strong focus on the interpretation of CP data, troubleshooting, and migration of problems that arise in both galvanic and impressed current systems, including design calculations for these systems. Classroom instruction is comprised of lectures and hands-on training, including using equipment and instruments for CP testing.

Course learning objectives

• Define activation, concentration, and resistance polarization, and the mathematical expressions of these concepts
• Recall the factors that affect polarization (area, temperature, relative movement, ion concentration, oxygen concentration)
• Apply the NACE criteria for CP and make necessary adjustments
• Identify errors in data collection/CP measurements including contact resistance errors, voltage drop errors, and reference electrode errors where the technologist is employed
• Determine the ideal current distribution for a CP system based on different affecting factors
• Apply advanced cathodic protection testing using correct measurement techniques to monitor CP system performance, and accurately interpret the data collected to ensure optimum CP system performance
• Determine corrective action to the CP system if necessary
• Conduct and document interference tests to determine if DC or AC interference exists, identify the source, and implement a method of control to mitigate the effects of stray current
• Design and install simplistic forms of galvanic and impressed current cathodic protection facilities and perform the necessary mathematical calculations

Course completion

Successful completion of the course is required to earn a certificate of course completion. Requirements are specific to each course and may include a combination of attendance, daily assessments, activities, quizzes, or knowledge checks.
