Not all tank inspections are performed to the same standard—and the code your inspection provider follows plays a major role in the quality and accuracy of your results. API 653 and EEMUA 159 are the two most widely used guidelines for aboveground storage tank inspections, each offering unique benefits depending on the tank’s design, age, and service conditions.
API 653 provides a comprehensive framework for assessing shell, floor, and roof conditions, as well as requirements for repairs, alterations, and re-rating. It’s commonly used for large petroleum and chemical storage tanks. EEMUA 159, on the other hand, offers more flexibility in certain service conditions and includes practical guidance for measuring corrosion, settlement, and structural performance—making it especially valuable for operators seeking a more detailed view of long-term degradation.
Choosing an inspection provider with expertise in both standards ensures your tank is assessed correctly and that maintenance recommendations align with your operational and regulatory needs. Accurate code selection leads to better planning, safer operations, and improved asset longevity.
