Course Description

This course provides an in-depth understanding of API 653 standards for inspection, repair, alteration, and reconstruction of aboveground storage tanks. Participants learn tank design, corrosion evaluation, inspection intervals, repair methodologies, and compliance with API 650, API 653, and related standards. The course includes case studies, practical exercises, and exam preparation for API certification.

Course Objectives

This course is designed to prepare participants for the API 653 Aboveground Storage Tank Inspector Certification examination while developing the practical knowledge and skills required to inspect, evaluate, repair, alter, and reconstruct aboveground storage tanks in accordance with API 653 and related industry standards. Participants will gain a comprehensive understanding of tank design, inspection planning, corrosion assessment, fitness-for-service principles, repair methodologies, welding requirements, non-destructive examination (NDE), and regulatory compliance to ensure the safe, reliable, and cost-effective operation of storage tank assets.

Audience

Tank inspectors, QA/QC engineers, maintenance engineers, engineers seeking API 653 certification.

Prerequisites

Basic understanding of tank construction and inspection processes; knowledge of welding and NDE methods is advantageous.
