Above-Ground Storage Tanks

Maintaining above-ground storage tanks is important for securing the product within the tanks, and it is also necessary for compliance with regulatory requirements and industry standards such as API 653.  Whether you are building new tanks or maintaining existing tanks, routine inspection is vital for ensuring the integrity and operability of these assets.  Inspections are not only preventive services, but they also serve as a way to identify the source of an existing problem and therefore mitigate the risk of reoccurrence.

New construction projects require extensive visual inspection, NDT such as radiography and phased array.  These services are necessary for ensuring that the safe and successful completion of your project not only aligns with your expectations, but also meets necessary regulatory and industry requirements.

For in-service inspections, our experts conduct a series of services such as thoroughly reviewing tank exterior and coating, checking for leaks and corrosion, inspecting nozzles and gaskets, performing UT thickness readings, evaluating fitness-for-service functionality and more.   

At the conclusion of our tank inspection services, and should repairs be needed, our experts provide a recommended repair plan.  If repairs are made then our personnel can re-inspect the affected asset, providing a supplemental report of the findings.

As above-ground storage tank assets age, extending their safe operating cycle becomes more important.  Deformation of walls, ceiling and/or floor can cause leaks, issues with accurate product tank volume readings and contribute to dangerous and costly failures.  Intertek’s inspection crews can use 3D laser scanning to capture and quantify these dimensional abnormalities.

Our industry-leading technical experts support tank farms and terminal operations with a full line of services that minimize risk, improve safety and ensure asset reliability.  Contact us to learn more.
