API 653 - Aboveground Storage Tank Inspector Certification

Course Description

This program prepares participants for the API 653 Aboveground Storage Tank (AST) Inspector certification exam. It covers the full lifecycle of storage tank inspection including in-service inspection, corrosion assessment, bottom/shell/roof evaluation, settlement analysis, fitness-for-service determination, and tank repair and reconstruction procedures. The course aligns with API 653 and references API 650 for design and construction requirements.

What you'll learn in this Course?

The API 653 Aboveground Storage Tank Inspector Certification program is a structured, exam-focused course for engineers and inspectors pursuing API 653 certification. It covers the complete scope of in-service tank inspection including design references from API 650, bottom and shell corrosion assessment, roof inspection, settlement evaluation, fitness-for-service determinations, and tank repair and reconstruction requirements. The program aligns with API 653, API 650, API 571, and API 579, integrating practical calculation exercises, case studies from operating terminals and refineries, and comprehensive mock exams. Participants leave with the technical competence and examination readiness to succeed in the API 653 certification and perform effectively in tank integrity roles.

The module highlights how thoughtful planning can directly improve project quality, reduce accidents, and help projects finish on time and within budget.
