Cathodic Protection 3 - Technologist (CP3)

The Cathodic Protection Technologist certification indicates knowledge of theoretical concepts and practical application of cathodic protection with a strong focus on interpretation of cathodic protection data, and cathodic protection troubleshooting.

The Cathodic Protection Technologist course builds on the technology presented in the Cathodic Protection Technician course with a strong focus on interpretation of CP data, trouble shooting 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.

Who should pursue and apply?

This program is intended for persons with extensive field experience and a strong CP technical knowledge who need an understanding of CP design procedures based on an improved knowledge of CP concepts.

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 ideal current distribution for a CP system based on different the affecting factors
  • Apply advanced cathodic protection testing using correct measurement techniques to monitor CP system performance, 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 and end of course exam

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.

Certification exams

Certification requirements include case-based and theory exams delivered via computer-based testing (CBT).

The multiple-choice CBT exam is scheduled separately from the course and delivered via Pearson VUE. The initial CBT exam is included with the course registration. Any Exam retake will incur additional cost to the applicant.

Renewal requirements

An approved recertification application is required every 3 years. The work experience requirement for renewals for all certifications is one and half (1.5) years for the most recent three (3) year period. Additionally, some certifications have other requirements related to responsibility in charge.

As you prepare for renewal, please visit My Certification Portal to log and manage your work experience and Professional Development Hours (PDH's) needed. Your work experience and PDH's will be submitted as part of your renewal application but you can input PDH's at any time. See the certification renewal guide for PDH's requirements, our sample training PDH guide, and our PDH how-to videos.

Certification holders are required to pay a non-refundable processing fee for renewal.

NOTE: AMPP reserves the right to return any incomplete applications or those that do not meet the requirements. All application fees are non-refundable. To avoid processing delays or forfeiture of fees, please ensure that the application is complete, meets all the requirements and payment has been received.
