Storage Tank Inspection – Non-Destructive Testing (NDT)

Non-Destructive Testing – Safety Without Interruption

For those of you who are unfamiliar with non-destructive testing (NDT) testing, this page will provide a basic overview of NDT and the most popular test methods and techniques used to help you get the most out of your fuels and tanks.

Benefits of non-destructive testing

✔ Identifies areas of degradation before failure occurs to ensure longer life expectancy
✔ Minimises downtime to ensure maximum productivity of tanks
✔ Offers trend information on deterioration so that predictions can be made
✔ Demonstrates operation standards and compliance e.g. EEMUA 159 and API 653
✔ Gives you peace of mind that your fuel tank is in sound condition

The importance of non-destructive testing

When storing fuel, it’s important to regularly test the tank and associated pipework to check its integrity. If left unmonitored, it can lead to costly spills and leaks which will have a significant negative impact on the environment.

Over time, fuel degrades in quality which can lead to hidden flaws, cracks and corrosion in tanks. Even minor damage can hugely increase the risk of a tank failure.

If your stored fuel results in pollution you could be fined or prosecuted, not to mention experience lost contracts, operational downtime, clean-up costs and increased insurance premiums. So why risk it?

What is NDT?

Companies who store fuel should regularly carry out assessments of all storage facilities. As well as regularly checking the appearance of your fuel yourself, you should use a qualified technician to undertake a more detailed inspection or your storage facilities at least every 6 months.

Non-destructive testing (NDT) is the only method to see the exact current ‘health status’ of a tank. It uses measurement techniques to pinpoint any damage and anomalies in the fuel stored inside.

Examples include magnetic-flux leakage (MFL) and ultrasonic testing (UT) which assess the quality equipment walls without damaging them.

Following analysis, you will be given a comprehensive report that can be used to satisfy insurance or compliance inspection by regulatory authorities.

The HSE recommends that NDT testing should be carried out at least every 10 years. However, with some COMAH sites, testing is required every 5 years.

There is a wide range of NDT tests on offer to suit whatever your requirements, such as:

✔ Ultrasonic inspection
✔ Tank thickness testing
✔ Tank weld testing

✔ Tank base testing
✔ UAV inspections
✔ Hardness testing

Who can carry out NDT?

The tell-tale signs of degraded tank integrity include phase separation, water in the fuel, blocked filters and engine failure. There’s no point in treating the symptoms without addressing the root cause. This is where we come in.

Crown Oil Environmental is an industry-leading company that’s approved to ISO 9001 standards. We employ two of the UK’s leading chemists and have onsite laboratory facilities to identify any fuel quality issues, with a team of experts on hand ready to undertake an inspection of your storage facilities.

By undertaking a proactive approach rather than reactive, you will prevent business downtime and having to fork out hefty clean-up costs from environmental damage. When was the last time someone checked your tank integrity?
