When evaluating cracks in the shell to bottom weld, what must be done?

• A. Evaluate per the "As built" Standard
• B. Remove the cracks
• C. Evaluate on a case by case basis
• D. Evaluate per API 579

Answer: (B)

In the context of evaluating cracks in the shell to bottom weld of aboveground storage tanks, considering the safety and structural integrity of the tank is paramount. The correct approach is to remove the cracks as identified. This is crucial because cracks can lead to failure in the weld, potentially causing leaks or catastrophic failures, which pose significant safety and environmental hazards. Removing the cracks allows for a complete assessment of the integrity of the tank and ensures that any potential weaknesses are addressed. It is essential to repair or remove defects according to accepted industry standards to maintain the tank’s structural integrity and operational reliability. Furthermore, addressing these issues promptly can prevent further degradation and avoid costly repairs in the future. While other evaluation methods may provide additional insights into the structural condition or be part of a larger assessment process, directly removing the cracks addresses the immediate concern and mitigates the associated risks effectively.
