Maintaining the ageing infrastructure such as underground pipelines is a challenge to the oil and gas industry worldwide. Corrosion is one of the major causes of ageing the industrial infrastructures. Understanding its mechanism and how to control it can lead to a remarkable re-education in the operation cost of piping and static equipment.

Cathodic Protection (CP) is one of the most widely used methods to control corrosion in industry. The Cathodic Protection is a method of that eliminates the corrosion of metals by the use of sacrificial anodes or the application of an electric current. It is a technique that has been known for 160 years, and is extensively applied to pipelines and tank farms, etc with great success. However, despite this long history and broad applicability, it is a technique that is all too often inadequately or even improperly applied; with the result that structures are poorly protected or, worse, adversely interfered with.

This 5-day GLOMACS Cathodic Protection System in Oil & Gas Exploration Industry training courses provides you with fundamental principles, evaluation and applications of Cathodic Protection, helping participants recognise them, select Cathodic Protection control methods and apply them to protect the assets of the organisation.

This GLOMACS training courses is designed to provide:

• The theoretical basis and the practical ability necessary operate and maintain Cathodic Protection (CP) systems in the oil and gas surface production facilities
• Understanding of the basic principles of corrosion and applications of galvanic and impressed current CP systems
• Understanding of the field equipment used to monitor CP systems and how they work
• Understanding of the various factors that impact the performance of these systems
• Learn about essential CP monitoring techniques to ensure effective operation
• Understanding of increase productivity by avoiding costly shutdowns thus reducing the cost of the overall corrosion control program

This training courses combines sound engineering principles, methods and applicable standards

• All lectures are interspersed with interactive discussion
• All lectures include group discussion, case history and exercises
• Actual major incidents as well as industry experience are reviewed
• Participants receive a multicolor course manual
• Pictures of real incidents and case history are shown
