Oil Tank Leaks: Causes and Solutions
Leaking oil tanks are a major problem that can lead to contamination of the environment, health hazards, and costly clean ups. It is important to understand the possible causes of leaking oil tanks and how these can be addressed to prevent further problems.
In this article we will examine some of the most common causes of oil tank leaks and provide information on the solutions that can be adopted to address them.
Aging Tanks
Above ground and in ground oil tanks have a finite service life. If not properly maintained, they can become vulnerable to corrosion, cracking, and in extreme cases, rupturing. As a general rule, tanks that are over 20 years old should be inspected to determine their current condition and assess the risk of leakages. The most effective way of doing this is to undertake visual inspections and/or use non-intrusive testing methods, such as ultrasonic or radar scans.
When tanks are identified as nearing the end of their service life, planning will need to be done to investigated options for replacement or refurbishment. If stainless-steel tanks are used, then the service life is extended, however for the cost effectiveness, these are often only used for larger tanks and critical applications.
Permanent Tank Sealing and Leak Detection
In certain cases, it may be desirable to permanently seal an oil tank, rather than replace it. This is generally because a tank may have been inspected and found to have reached the end of its service life, yet running costs are lower than the cost of installing a new replacement.
Permanent tank sealing involves sealing the tank and its associated pipes, valves and fittings to prevent leaking. During permanent tank sealing, any cracks or damage to the oil tank is identified and sealed and any joints and connections checked.
Leaks can also be detected and prevented with the use of leak detection systems. These systems are designed to identify and monitor for data or tension-producing changes in the structure of the tank, such as weakening of supports, reductions in the level of liquid present, or changes in air pressure.
Improper Storage
One of the most common causes of oil tank leaks is improper storage and handling. This can include storing the oil tank in a location where it is exposed to the elements, such as direct sunlight or extreme cold, using incorrect fuel grades, or storing the oil tank in an insecure manner.
When it comes to proper oil storage and handling, preventative measures should be taken to ensure the tank is protected, a good quality fuel is used and any loose connections or fittings are treated immediately.
Conclusion
Leaking oil tanks can cause serious problems for individuals, businesses and the environment. It is important to understand the possible causes of oil tank leaks, signs that the tank is aging or developing a fault, and measures that can be taken to prevent and contain leaks.
By taking the time to learn about the causes of oil tank leaks and the measures you can take to protect your assets and the environment, you can help to ensure that leaking oil tanks do not become a problem for you and your family.
