Tanks built to API 650 and its predecessor API 12C that are in-service are covered by API-653. Tank foundation, bottom, shell, structure, roof, attached appurtenances, & nozzles are all required to be inspected. Inspections are required at recommended intervals to remain compliant with code and environmental regulations.

 
What is API 653 for ABOVE-GROUND Storage Tank Inspection?

API 653 applies to above-ground storage tanks that are built to API-650 or API 12C. The standard regulates how those tanks should be maintained, inspected, repaired, or altered. Not just anyone can do an API 653 inspection – regulations require they be administered by a certified inspector.

All storage tanks deteriorate over time. If they aren’t properly maintained and monitored, it’s just a matter of time before problems can occur. Regular inspections protect your equipment, your facility, your staff, and your community from the possibility of failure. Utilizing insight from inspections to improve safety and maintenance can also improve your storage tank’s lifespan.
