Storage Tank Assessment

Storage Tank Assessment

Ensure the Safety of Your Storage Tanks

In 1985, the U.S. Environmental Protection Agency (EPA) created the Office of Underground Storage Tanks, to execute a Congressional mandate to develop and implement a regulatory program for underground storage tank (UST) systems.

To help companies comply with this mandate, TÜV Rheinland provides storage tank assessments performed by qualified, experienced personnel in a timely and cost-effective manner. In addition to experts qualified in testing, sampling, and analysis, we also provide costly inspection equipment, saving you the costs of having to buy it yourself.

Our Storage Tank Assessment Services

Performed by qualified professionals, TÜV Rheinland’s storage tank assessment services cover:

  • Out-of-service inspections – the Code of Federal Regulations CFR 1910 recommends that an out-of-service inspection be performed every 10 years on above-ground storage tanks

Products Covered

Our services cover both above-ground and underground storage tanks.

Approach

TÜV Rheinland’s storage tank assessment services approach is as follows:

  • Initial site assessment
  • Investigation
  • Prevention plans
  • Monitoring and management programs

An in-service inspection is usually performed on the exterior of the tank. If the tank is insulated, certain spots will need to be removed. Ultrasonic thickness measurements then need to be taken, to look for thickness variations that require repair. If the tank is not insulated, a tank crawler (an instrument that takes UT readings at a predetermined interval) can be deployed, as well as a complete visual examination. These exterior inspections can be performed every 5 years.

The out-of-service inspection requires an inspection of the interior of the tank to include, but not limited to, the tank floor, shell coarses, chime weld, roof, nozzles, and containment burn. All welds are inspected either ultrasonically, using a vacuum box, dye penetrant, or magnetic-particle inspection. The tank first needs to be cleaned and free of debris. Then the tank floor is Magnetic Flux Exclusion (MFE) floor scanned, to look for bottom-side corrosion. The welds on the floor plate welds and chime welds are vacuum box inspected. The shell coarses are visually examined, to look for pitting, and ultrasonically inspected. All supports, nozzles or entry points, including the roof, are also inspected.

More Information
