Excellence Integrity Management

A storage tank can operate for decades without problems.

Or it can become a major safety, environmental, and financial risk because of a single inspection oversight.

The difference often comes down to one thing:

A disciplined integrity management program.

API 653 remains the industry benchmark for inspecting, repairing, altering, and reconstructing above-ground storage tanks. Yet many organizations still struggle with issues such as:

• Bottom plate corrosion
• Floating roof seal deterioration
• Foundation settlement
• Cathodic protection failures
• Incomplete inspection records

- Pre-inspection planning
- External and internal inspections
- Ultrasonic thickness measurements
- Weld assessment
- Settlement evaluation
- Cathodic protection review
- Fitness-for-Service (FFS) assessments
- Risk-Based Inspection (RBI) integration
