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.

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.

This interactive Training will be highly interactive, with opportunities to advance your opinions and ideas and will include;

• Lectures
• Workshop & Work Presentation
• Case Studies and Practical Exercise
• Videos and General Discussions
