The course is divided into six main areas: Basic Storage tank design engineering i.e. API 650, In-service inspection techniques (API 653/ RP 575/ RP 577), Damage mechanisms (API 571), Cathodic protection (API RP 651) and lining of tank bottom (API RP 652), calculations of retirement thickness and other skills required for delivery of quality job & safe operation. The participants will receive comprehensive course notes, illustrated with practical case studies, main punch-points of the course to impart knowledge to participants.

By the end of this course delegates will learn about:

• • Main concepts and technical content of API 653 Code and the other reference codes
  • Concept of metal degradation.
  • Design fundamentals of storage tank (API 650).
  • Evaluation of tank integrity of shell, bottom and roof. Thickness calculations for intended design conditions or revised design conditions.
  • How to clarify the need of Cathodic Protection and lining of tank bottom.
  • Evalution and decision for remedial action in Tank Settlement.
  • How to estimate remaining life of tank and decide inspection intervals. Be able to choose the appropriate inspection tools and inspection intervals.
  • Carry out re-rating, remaining life and retirement thickness calculations.
