Keep Your Above Ground Tanks Safe and Well Maintained with an API 653 Inspection

Two worker discussing below large storage tanksWhen it comes to storing petroleum, you have two options: above ground and below ground. Each has its pros and cons. Many prefer the former since they can monitor problems carefully. Maintaining such tanks is also more convenient.

Regardless of how often you upgrade or maintain these tanks, however, you still need to undergo an inspection.

What Is API-653 Inspection?

It is an investigation mandated by the American Petroleum Institute (API). It is a national trade organization that covers all aspects of the oil and gas industry in the country. It promotes different certifications, some of which you can get after an inspection.

One of these inspections is API 653. For you to qualify for this inspection, the tank must have a diameter of no less than 30 feet and a height of 50 feet. Although the primary goal is to check the condition of the tanks, it will also include repair, alteration, and maintenance.

What Are the Intervals?

Many factors can affect the length of time in between inspections. These include the degree, presence, or severity of corrosion; location of the tanks; systems and processes used by the company; the type of product the tanks stored; and the result of the previous inspection.

It also depends whether the inspection is external or internal. The former usually occurs every four years while next internal check-up should be within ten years of the previous service.

Who Can Perform the Inspection?

There are two kinds of people who can inspect the tank: you or your employees, as well as a certified API 653 inspector. You will be responsible for the monthly monitoring of the tanks, and you don’t need a certification for that. For both external and internal check-up, you need to hire an above ground tank certified inspection specialists have at least 5 to 10 years of review experience.

For the sake of safety and compliance, have professionals check your tanks regularly.
