Description

The CP 3–Cathodic Protection Technologist Course is an intensive 6-day course that presents CP
technology to prepare students for the NACE Cathodic Protection Technologist Certification
Examination. The CP 3–Cathodic Protection Technologist Course builds on the technology presented
in the CP 2–Cathodic Protection Technician Course covering both theoretical concepts and practical
application of cathodic protection with a strong focus on interpretation of CP data, CP troubleshooting
and mitigation of problems that might arise in both galvanic and impressed current systems. The
course is presented in a format of lecture, discussion and hands-on, in-class experiments and group
exercises. There is a written examination at the conclusion of the course.

Who Should Attend  

This course is designed for persons who have extensive CP field experience and a strong technical
background in cathodic protection. Students must complete a preliminary application for certification
at least 60 days in advance so that education and prerequisites can be verified.

Course Highlights

  • CP Theory
  • CP Criteria
  • CP Interference
  • Detecting Stray Current, AC Interference, and Telluric Current Interference
  • CP Design Fundamentals
  • Design Calculations (circuit resistances, system capacity and life, number of anodes, driving
    voltage)
  • Evaluation of System Performance
  • Troubleshooting Cathodic Protection Systems

Skill Assessment

Upon successful completion of the CP Technologist Examination, a Certified NACE Cathodic
Protection Technologist will have passed a written examination with a grade of 70% or greater that
will include various levels of assessment of the following skill and knowledge factors:

  • Understand activation, concentration and resistance polarization and the mathematical
    expressions of these concepts.
  • Understand the factors that affect polarization (area, temperature, relative movement, ion
    concentration, oxygen concentration).
  • Understand the NACE criteria for CP and be able to apply the criteria and make adjustments
    as necessary to CP systems in order to comply with the criteria defined by the company
    where the technologist is employed.
  • Understand the concept of current distribution and be able to determine ideal current
    distribution for a CP system taking into account the factors affecting current distribution
    (anode-to-cathode separation distance, electrolyte and structure resistivity variation, current
    attenuation).
  • Perform 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. Based on data collected, determine if
    correction/modifications to system components are necessary.
  • Identify errors in data collection/CP measurements including contact resistance errors,
    voltage drop errors and, reference electrode errors.
  • Conduct and document interference tests where stray currents are suspected to determine if
    interference exists and identify the source of the interference.
  • Upon determination of interference, identify and implement a method of control that will
    mitigate the effects of the stray current.
  • Design and install simplistic forms of galvanic and impressed current cathodic protection
    facilities and perform the necessary mathematical calculations.

Reference Materials Included with Course Registration Fees:

Students will receive the CP 3–Cathodic Protection Technologist Course Manual on CD-ROM prior to the start of
the course. A hard copy of the course manual will be provided to students on-site.

Exam-Only Option

Candidates meeting the prerequisites listed can sit for the CP Technologist Examination without
taking the class. The exam is open book so that candidates can bring their own references.
Candidates will receive a copy of the course manual. Exams are scheduled to coincide with
scheduled courses. Exam-only candidates may only attend the course on the day of the exam.
Contact NACE first Service for more information. Registration fees for exam only candidates are non-
refundable.
