CP 3-
Cathodic Protection Specialist
6-Day Classroom Course
Description
The CP 4-Cathodic Protection Specialist Course is an intensive 6-day course that focuses on the principles and procedures for CP design on a variety of structures for both galvanic and impressed current systems. The course discusses the theoretical concepts behind the design and considerations that influence the design (environment, structure type/materials of construction, coatings), design factors, and calculations (including attenuation). The course involves lecture and in-class discussion and practice with design examples on various structures (i.e., pipelines, tanks and well casings, offshore applications and steel reinforcing in concrete structures). The course concludes with the written CP Specialist Examination.
Who Should Attend
This course is intended for those involved in the design, installation, and maintenance of CP systems. Prior to taking the exam or the NACE training course, students must have completed college or university-level courses in algebra, geometry, and trigonometry, and must have significant amounts of practical experience in CP Design. NOTE: The CP Specialist Examination is challenging, and the CP 4-Cathodic Protection Specialist Course is designed as a refresher course for persons already meeting the experience and education prerequisites for the exam. There is not a direct progression from Cathodic Protection Technologist to Cathodic Protection Specialist. Participating only in the CP 4-Cathodic Protection Specialist Course does not ensure success on the Cathodic Protection Specialist Examination. Substantial experience involving all aspects of cathodic protection, including design and formal education in math/science/engineering is critical to students' success in the course and examination. Attendance at the CP 3-Cathodic Protection Technologist Course is strongley recommended before sitting for the CP 4-Cathodic Protection Specialist Course or Examination Only Option. The examination is open book and students are welcome to bring any reference material they would like to the examination.
