Storage Tanks API 650, including API 653 (Standard for Tank Inspection, Repair, Alteration, and Reconstruction)

 

Overview:

This intensive course provides a comprehensive understanding of the design, construction, inspection, repair, alteration, and reconstruction of aboveground welded steel storage tanks in accordance with:

  • API 650 – Welded Tanks for Oil Storage

  • API 653 – Tank Inspection, Repair, Alteration, and Reconstruction

Participants will gain practical knowledge of tank design principles, material selection, fabrication requirements, in-service inspection methodologies, damage mechanisms, fitness-for-service assessments, and repair techniques used in oil & gas, petrochemical, mining, and energy sectors.

This course bridges the gap between tank design (API 650) and lifecycle integrity management (API 653).
