Course Description
Corrosion problems have always presented a severe challenge to oil and gas producing operations. Operators plan for long periods of continuous production with maintenance schedules for the prescribed shutdown periods. Unfortunately, corrosion does not always respect these schedules, resulting in severe economic penalties due to loss of production. In addition, the risk of pollution and hazards to safety are other important reasons for adequate corrosion engineering.
The course considers external protection using corrosion resistant materials, coatings, and cathodic protection. The importance of internal corrosion and its prevention will be examined with emphasis on material selection, coatings and use of corrosion inhibitors.
The contribution of inspection (non-destructive testing), and corrosion monitoring to the overall operation will be considered in detail. Corrosion problems concerning “risers” and subsea-lines will be considered together with methods for protection.
The Training Course Will Highlight ?
Training Objective
Upon completion of this course, you will gain an understanding of corrosion engineering in oil and gas production involving the various methods available for corrosion control, regulatory and safety matters, and the contribution of an integrated monitoring and inspection programme for operations and diagnosis of problems.
Target Audience
The course is designed essentially for process and mechanical engineers employed by the operating companies engaged in oil and gas production. The material is also appropriate for those personnel concerned with specialist functions in the oil industry including inspection, material selection, and corrosion control, as well as those involved in R&D.
Staff of service companies providing corrosion inhibitors and overall corrosion services should also find this course beneficial, together with companies or manufacturers marketing materials, coatings and equipment for cathodic protection, inspection (NDT) and corrosion monitoring.
