Cathodic Protection Specialist (CP4)

Cathodic Protection Specialist (CP4)

The Cathodic Protection Specialist certification covers the theoretical concepts behind the design and considerations that influence the design and calculations (including attenuation) of a cathodic protection system. It is for individuals who are responsible for the design, installation, and maintenance of cathodic protection systems.

Who should pursue and apply?
This program is intended for persons with extensive CP work experience and technical knowledge. Those who achieve this certification are leaders in the field of CP concepts, design, and systems.

CP4 Cathodic Protection Specialist course

The Cathodic Protection Specialist course focuses on the principles and procedures for CP design on a variety of structures for both galvanic and impressed current systems. The course discusses theoretical design concepts, considerations that influence the design (environment, structure type/materials of construction, coatings), design factors, and calculations (including attenuation).

Classroom instruction is comprised of lecture, in-class discussion, and practice with design calculations on various structures (i.e., pipelines, tanks and well casings, offshore applications, and steel reinforcing in concrete structures).

Course learning objectives

  • Design complete CP systems in a variety of industry applications including water tanks, aboveground and underground storage tanks, and pipelines
  • Demonstrate knowledge of rectifier and ground bed installation, along with source code calculations and protective coatings
  • Perform corrosion analysis on the job site
  • Manage and direct field tests
  • Apply new technologies to existing CP programs
  • Provide formal training to understudies on basic and advanced CP concepts
  • Recall and comply with codes, regulations, reporting procedures, and standard practices

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.


There are no prerequisites for this course.


Cathodic Protection 3 – Technologist or equivalent training

To be successful in this course, it is strongly recommended that students have completed college or university-level courses in algebra, geometry, and trigonometry, and have significant practical experience in CP design.
