What is fuel tank decommissioning?

Tank decommissioning is the securing of an oil tank which is no longer required by degassing it before removing it or filling it with an inert substance to prevent it from regassing over time. We offer several types of tank decommissioning, including foam filling and tank removal.

Why do fuel tanks need to be decommissioned?

Fuel storage tanks corrode or rust at speed, determined by factors such as the quality of the stored fuel, the tank thickness, age and damage it undergoes over time. This rust and corrosion result in holes and leaks in the tank walls which are an environmental concern in terms of the fuel leaking into nearby soil or groundwater. Safely decommissioning your tank before you reach that point will save you the high costs and inconvenience of a fuel spill clean-up.

Aside from a failing tank, there are other reasons to decommission a tank, including the closure of petrol stations, upgrading to new storage systems, site relocation or simply due to the owners no longer requiring the fuel tanks on a temporary basis. If the oil is simply left in the tank, it can begin to corrode or degrade over time which can pose a risk to the environment. Therefore, the liquid and gases stored in tanks need to be fully removed.

Foam filling

Foam filling is a flexible, safe and reversible solution which involves filling a tank with RG22 foam. This product is light enough to not damage the tank but also provides reinforcement, enabling the tank to withstand external damage.

Tank foam filling is one of the least disruptive methods of decommissioning an oil tank and can be removed in the future if you wish to put your tank back into use. It’s an extremely popular service with our forecourt customers due to the complete flexibility and more cost-effective nature when compared to full tank removal.

Tank removal

If you no longer need the tank then removal is the safest method as it eliminates the hazard at source. Our engineers are highly experienced in removing old and damaged tanks from sites across the UK, disposing of them whilst adhering to all the required regulations. Regardless of whether you operate a large commercial steel tank or a domestic plastic tank, our experts can safely degas your tank(s) with minimal disruption.

Tank decommissioning by removal begins with a fuel uplift following by a tank clean to remove any remnants. Our engineers can carry out all of these services in-house, streamlining the entire process and providing end-to-end project management and support.

Concrete filling

Concrete filling tanks is a permanent solution to degas a tank, rendering it inoperable. This is typically used in old, underground commercial fuel tanks. This method, however, makes it hard to remove the tank once filled.

Thorough tank cleaning

Tank decommissioning involves the removal of all traces of liquid fuels, fumes and waste from the inside of the tank before it can be taken away. Tanks that store oil are classed as hazardous until they have been professionally cleaned. Our experts carry out industrial tank cleaning for a wide range of businesses across the UK.
