Cathodic Protection System in Oil & Gas Industry
Details :
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 reeducation in the operation cost of piping and static equipment.
Cathodic Protection (CP) is one of the most widely
used methods to control corrosion control 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 training course 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 training course 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 course is suitable for personnel who
are working in technical areas related to materials, maintenance and integrity
who deal directly or indirectly with cathodic protection. They include:
- Corrosion Engineers and Technicians
