In-Service Tank Inspection and API 653: How Robotic UT Supports Integrity Decisions

A technical guide to using in-service robotic tank floor inspection data in API 653 integrity programs without confusing robotic UT with the authorized inspector's decision.

• Robotic UT does not replace API 653 or the authorized inspector; it improves the evidence available to them.
• The strongest use case is shutdown prioritization, corrosion-rate trending and planning the next out-of-service scope.
• In-service inspection is still subject to product compatibility, access geometry, hazardous-area certification and inspector acceptance.
