Cathodic Protection 3 Refresher

Cathodic Protection Technologist (CP3) Refresher Course - Virtual

Refresh your CP knowledge before your certification exam with our virtual CP3 Refresher Course. This one-day course highlights the material in the CP3 Technologist five-day class. The one-day virtual course is designed for those who would like a review of the CP3 course with a live AMPP-certified instructor to refresh their skills.

Who should attend

Students who have previously taken the in-person or virtual CP3 Technologist class and would like to review the course material.

Upcoming Courses

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)
  • Identify errors in data collection/CP measurements including contact resistance errors, voltage drop errors, and reference electrode errors where the technologist is employed.
  • Determine ideal current distribution for a CP system taking into account the factors affecting current distribution.
  • Learn advanced cathodic protection testing using correct measurement techniques to monitor CP system performance, accurately interpret the data collected to ensure optimum CP system performance and determine the correction action to the system, if necessary
  • Observe and document interference tests to determine if interference exists and identify the source of the interference 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.
