Corrosion problems have always presented a severe challenge to oil and gas producing operations. Operators plan for long periods of continuous production with maintenance scheduled for the prescribed shutdown periods. Unfortunately, corrosion does not always respect these schedules, resulting in severe economic penalties due to loss of product. In addition, the risk of pollution and hazards to safety are other important reasons for adequate corrosion engineering. Moreover; corrosion hazards have intensified with extraction in deeper waters and in more hostile environments. Innovations aimed at reducing offshore field development costs involving reductions in platform weight, increasing use of satellite wells and subsea manifolds require specific attention to corrosion prevention. This course conforms to NACE standards.

By the end of this course delegates will be able to:

• Identify potential corrosion problems and communicate effectively with other corrosion professionals
• Know the causes of corrosion and the methods by which it can be identified, monitored and controlled
• Learn components and operating characteristics of galvanic and impressed current systems
• Understand the factors to evaluate Cathodic protection system performance, interpretation of data and common measurement errors
• Correctly write a coating and lining system specification with enough confidence and certainty avoid the pitfalls and traps that cause coating failures
• How to reduce corrosion costs by developing designs that include corrosion control
• How to utilize API 570 “Piping Inspection Code,” API 574 “Inspection Practices for Piping System Components” , NACE MR0175 and MR0103
• How to inspect piping while “in-service”, “out of service” and underground piping
