API 650 requires a minimum bottom plate thickness of 0.25 in. It does not mandate an internal lining, cathodic protection system, nor secondary containment and leak detection system. An owner wants to maximize the required interval between internal inspections, typically targeting for 10 years. The owner will typically be able to estimate anticipated corrosion rates for both the liquid and soil sides of the tank based on past experience. The question that must be answered is whether a standard API 650 tank design is acceptable, considering API 653 requirements and the owner's maintenance, inspection planning and operational requirements.

By the end of this course delegates will be able to:

• Gain an overall understanding of the maintenance requirements of aboveground atmospheric storage tanks in accordance with API-653
