Methodology

This course combines sound engineering, operation and maintenance principles, applicable standards, and best industry practices for reliable and cost-effective process plant systems. Delegates will be encouraged to introduce problems of their own for discussion and analysis. Copies of all lecture materials, case studies, and workbooks will be provided. Group discussions will be carried out on problems faced.  This training program is lecture-based and customized to the needs of the audience, providing a meaningful experience for personnel who work in petroleum plants. Daily sessions include formal presentations, prepared in PowerPoint, interspersed with directed discussions and case studies. In addition to formal lectures and discussions, the delegates will learn by active participation through the use of problem-solving exercises, group discussions, analysis of real-life case studies, etc. Many relevant videos will be shown during the training.

All attendees receive a course manual as a reference.

• 30% Lectures
