Cathodic protection plays a key role in corrosion control in the oil and gas industry. It controls the corrosion of buried structures.
This course has been designed to provide participants with an understanding of the basic principles of corrosion mechanisms and focuses on the control of galvanic corrosion by the use of sacrificial anodes and induced current cathodic protection. The participants will learn the main components used in cathodic protection and methods used to safely test them and maintain them.
Upon completion of this course, participants should have a better understanding of the technology related to cathodic protection within the industry. Having this knowledge will help each technician develop confidence and professional enthusiasm, therefore, increasing their efficiency. The knowledge that technicians gained from this course will be further expanded by on-job training and practical experience they will receive throughout the duration of their career.
Principles of Cathodic Protection
- Chemistry of corrosion
- Galvanic corrosion
- Corrosion control
- Impressed current cathodic protection.
On the first day participants will be introduced to basic chemistry to explain corrosion mechanisms. They will learn about how to control corrosion due galvanic reaction. The typical layout of an impressed current cathodic protection system with the focus on anode installations and performance specifications will also be explained.
Testing and Maintaining Cathodic Protection Systems
- CP rectifiers
- Power supplies for remote locations
- Cables and bonding to structures
- Testing cathodic protection systems
On the second day participants will learn about the construction and operation of single phase and three-phase rectifiers. Rectifiers with manual and automatic output adjustments and safety associated with working around rectifiers will be explained. The participants will learn about Photo Voltaic (PV) and Thermal Electrical Generators (TEGs) that are used in remote locations to power cathodic protection systems. The day will conclude with topics on testing and maintenance of typical cathodic protection systems.
This course is designed for electrical technicians, maintenance planners, and supervisors with operation and maintenance responsibilities who work in an industrial plant.
Anyone taking this course should familiar with electrical installations in an industrial setting.
