Overview

The first use of a cathodic protection system dates back to 1825 when Sir Humphry Davy used malleable iron in a series of experiments to protect the copper clad ships of the Royal Navy. The iron served as a sacrificial anode, thus protecting the copper cladding from deterioration.

Since that time, cathodic protection has remained the most effective method in controlling corrosion and is commonly used on many types of structures, such as pipelines, underground storage tanks, locks, and ship hulls. It reduces corrosion by minimizing the difference in potential between anode and cathode. This is achieved by applying a current to the structure to be protected from some outside source.

This course introduces the student to the principles of both sacrificial and impressed current anode systems. The merits of each type are described and the process for designing each type of system is covered. Example problems are provided which demonstrate how to design an anode system to solve "real world" corrosion problems. The student is required to read and review the material contained in ARMY TM 5-811-7, Electrical Design, Cathodic Protection.

The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.

This course teaches the following specific knowledge and skills:

  · Define the Types of Cathodic Protection Systems.
  · Gathering Required Data to Determine Which System to Use
  · Design of Galvanic Systems
  · Design of Impressed Current Systems

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.
