With prolonged use and exposure to different contaminants, environmental conditions and chemicals, storage tanks become vulnerable to structural damages such as cracks, corrosion and fatigue. Therefore, it is both crucial and beneficial to keep an eye on these signs to prevent tank failure.
There are many techniques available to assess the condition and provide accurate results without damaging the tank physically. However, these techniques require specific instruments and expertise to carry out. Hence, you will need to engage NDT testing services to help you with this.
Network Environmental is a highly experienced fuel company that has been providing a complete range of fuel services in the UK for more than ten years. With a specialised team and state-of-the-art equipment, we can carry out a complete NDT tank inspection for your storage tanks.
Non-destructive testing (NDT) is a method used to inspect the health of a storage tank without damaging it physically. This method uses multiple materials and instruments to carry out the inspection.
NDT is used to assess the level of deterioration in a tank due to stress, corrosion, rust or any other chemical or physical factor. This method allows you to detect structural damages before complete failure and take preventive measures.
Visual Inspection: It is the most basic method of NDT, which involves looking for signs of visible damage, fatigue or deterioration. It is a swift and relatively easy method to keep track of the structural integrity of your oil storage tank.
Ultrasonic Testing: It uses high-frequency sound waves to detect flaws or measure the thickness of materials. In storage tanks, it can be used to identify corrosion, erosion, wall thickness variations, and weld defects.
Liquid Penetrant Testing: Liquid Penetrant Testing, or Dye Penetrant Testing, detects surface-breaking defects such as cracks, porosity, or leaks. A coloured liquid penetrant is applied to the surface of the tank, allowed to seep into any surface defects, before a developer is applied, which draws out the liquid and makes the defects visible.
Radiographic Testing: Radiographic Testing uses X-rays to penetrate the tank material and create an image on a film or digital detector. It is useful for identifying internal defects, such as cracks, corrosion, or weld imperfections.
Magnetic Particle Testing: Magnetic Particle Testing identifies surface and near-surface defects in ferromagnetic materials. The method involves magnetising the tank and applying ferromagnetic particles, which are attracted to the defects and make them visible.
Thermography: Thermography, or infrared imaging, is used to detect temperature differences on the surface of storage tanks. It can identify areas of insulation damage, moisture intrusion, or structural defects.
Acoustic Emission: Acoustic Emission Testing is employed to detect and monitor the release of stress waves or acoustic signals produced by active defects or crack growth within the storage tank. AE sensors are attached to the tank, and any acoustic activity, such as cracking or leaking, is detected and recorded.

A non-destructive testing, or NDT, is a method of testing the structural integrity of a fuel tank without damaging or harming the tank.
There are a number of tests carried out during the procedure, such as:
Yes, NDT uses the latest technology tools and techniques, and detailed NDT can provide an accurate picture of your fuel tank’s current condition.
HSE recommends carrying out an NDT every 5 years to ensure your fuel tank is structurally intact and does not pose any threat to you and the environment.
NDT requires the deployment of complex equipment and cutting-edge technology. That is why a trained professional should carry out the procedure.
If a problem is discovered, our staff will inform you of its extent as well as possible fixes. If the problem is beyond fixable, the engineer may recommend decommissioning and replacement of the tank.
We take pride in holding industry-recognised accreditations. These certifications demonstrate our commitment to quality and compliance, and provide our clients with peace of mind knowing that they are working with a reputable and trustworthy partner.
