API– 653 Above Ground Storage Inspector

Ref : API_653

This course is designed to give a detailed discussion on the required engineering knowledge for In-service Storage tanks with emphasis on syllabus published by API (Body of Knowledge) for the said examination. It includes all the code sections referred by API 653 committee to the extent required from examination point of view This preparatory course will clarify basic intentions of all code prescribed for study, how to interpret code rulings and at the end, built-up the confidence among the participants for taking decisions.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), In-service degradation 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 examples, Mock-examinations, main punch-points of the course and extensive question banks to give the participants the confidence for getting certified successfully.

Learning Objectives

The course provides participants with the knowledge necessary to:

  • To familiarize participants with the main concepts and technical content of API 653 Code and the other reference codes prescribed for Certification Examination.
  • To introduce participants to the concept of metal degradation.
  • To explain to participants the design fundamentals of storage tank (API 650).
  • To introduce participants to evaluation of tank integrity of shell, bottom and roof .Thick­ness calculations for intended design conditions or revised design conditions.
  • To clarify the need of Cathodic Protection and lining of tank bottom.
  • To Evaluate and decide remedial action for Tank settlement.
  • To explain to participants how to estimate remaining life of tank and decide inspection intervals. Be able to choose the appropriate inspection tools and inspection intervals.
  • To carry out re-rating, remaining life and retirement thickness calculations.
  • To Score very well in API 653 examination.
