API 653: Tank Inspection, Repair, Alteration, and Reconstruction

Introduction:

The API 653 Above Ground Storage Tank Certification Preparation course is designed to provide individuals with a basic understanding of above ground storage tank inspection, repair, alteration, and rebuilding. This training is meant to provide a thorough overview of the engineering knowledge required for In-Service Storage Tanks, with a focus on the API.

It contains all of the code parts alluded to by the API 653 committee to the extent that they are required from an inspection standpoint. This course will define the core purposes of all codes required for study, teach participants how to read code rulings, and build confidence in their ability to make decisions.

Targeted Groups:

• Storage Tank Inspectors & Engineers
• Plant Inspectors
• Inspection & Corrosion Engineers
• Process Engineers
• Inspection Engineers for Newly constructed and reconstructed tanks
• QA/QC inspectors
• Maintenance & Mechanical Engineers
• Inspection Testing Engineers
• Fabrication Engineers

Course Objectives:

At the end of this course the participants will be able to:

• Identify the API 653 Scopes, Suitability for Service, evaluation of the tank Shell and Min. accepted thickness also the maximum allowable fill Height
• Evaluation of the tank Bottom, including settlement and release prevention Systems (RPS)
• Recognize the reasons for Inspection and Causes of Deterioration
• Determination of Need for Cathodic Protection and Methods of Cathodic Protection
• Employ post weld heat treatment, identify the charpy impact testing
• Carryout welding discontinuities and discuss ASME section IX WPS &WPQ and PQR
