Storage tank cleaning and maintenance
We help operators with tanks on their sites minimise the risk of asset failure, leakages, content contamination, and pollution by providing regular storage tank cleaning and maintenance so that they can remain compliant.
Tank storage owners are at a crossroads with many underground tanks now 20 to 30 years old. But with traditional hydrocarbon fuels being phased out in the next 20 years, you want to avoid the cost to replace. Our tank cleaning and maintenance will extend asset life until such time as the tank is ready for decommission.
We clean and purge all types of storage tanks in a variety of sectors, from retail forecourts, transport, major refineries, and military estates with underground, ground-level, or above-ground systems.
We employ man-entry and non-man-entry techniques to remove and dispose of any condensation, water, or sludge in your tank in situations such as changes of stored product, grade changes, remove contamination, improve the lifespan of the asset, and prior to decommissioning.
Manual and automated cleaning options are available, including powerful remote-controlled mechanical washers that comply with current legislation for oil, alternative fuel, and foul tanks, and storage containers for chemicals, water, and any other liquid or gas.

Legislation
HSG 176
The Health and Safety at Work etc. Act requires that plant and equipment is maintained in a safe condition. Only personnel who are suitably qualified and authorised, and who fully understand the hazards, should carry out inspection and maintenance.
GPP2: Above ground oil storage tanks recommends:
- Your tank manufacture will be able to tell you what regular maintenance your tank needs. Use a registered competent person to check your tank, secondary containment, and pipework every year. You should receive a written report on the state of your tank after the inspection.
- Keep a log of the inspections, any repair work on your tanks and who’s done it.

The tank cleaning process
Scoping out
The client will provide an overview of the identified equipment to be cleaned, including volumes and historic knowledge about fouling levels, including any pyrophoric issues and H2S for chemical tanks.
Every tank clean begins with a site visit to discuss individual requirements and inspect your assets. We will identify critical access points, tie-in locations, and laydown areas.
The ‘scoping out’ phase will also include permit and planning work, certification, and practical recommendations of the safest, most economical methods of access, gas purging, clean-up, and inspection.
Cleaning techniques
A highly trained team will then employ the appropriate cleaning tools and techniques to clean your tank. This could encompass hot-water washing, cold-water spray, ultra-high-pressure jetting, shot blasting, specialist chemical cleaning, gamma jetting, 360⁰ cleaning heads, or manual wiping to remove rust, sludge and surface dirt from the tank’s walls, floor, and fittings.
We have qualified experts to perform mobile chemical tank cleaning. Our portable hydrogen sulphide scrubbing units allow us to clean out your tanks externally without the need for higher risk confined space entry. When complete we vacuum out the hydrogen sulphide through Ex fans to neutralise it.
We have developed many successful chemical cleaning procedures which address a variety of issues. These include Chemical removal of heavy deposits from tanks, boilers, pumps, pipework etc, storage tanks with failed heating coils, and hardened/aged deposits that prevent coil extraction and replacement, and chemical washing of road and storage tanks to remove residues and facilitate product change.
Chemical tanks
Chemical infrastructure seals and valves typically have a shorter lifespan. Our experts can uplift whatever chemical is in your tank and hold it in one of our tankers to allow it to be cleaned and for maintenance activity to take place on your tank before returning the chemical.
Tank assessment
As part of a complete end-to-end service, general tank health and structural integrity are assessed via pressure testing, identifying deterioration and potential leak and spill hazards.
Fuel polishing
Fuel polishing specialists can also eliminate invasive water, free water sediment and microbial contamination.
Waste disposal
Tanks are then restored to full operational order and waste is efficiently transported and treated for compliant disposal.
Remote tank clean
Using our non-man entry, ATEX Zone 1 device for tank cleaning and visual inspections, AdlerView™ can be used to remotely clean and inspect fuel tanks both above and below ground, from a van positioned up to 50 metres away.
The device vastly reduces the costs associated with removing tank lids and improves health and safety of traditional man-entry tank cleaning.
As well as being ATEX Zone 1 registered, the AdlerView™ has improved lighting, control and movement and is waterproof. A full report and video of the inside of the tank will be produced on behalf of the client to demonstrate the effectiveness of the clean.
Man-entry tank cleaning
Where a remote tank clean is not possible or practical, our qualified confined space entry technicians will enter the tank and employ the relevant cleaning type to clean the inside of your tank and report on its condition with photos and video.
Complex tank cleaning
We help organisations to improve the storage capacity of their systems by removing the build-up of silt, stones and rag from complex storage tanks allowing them to store more product.
Tank lining
Our double skin tank enhancement system is a cost-effective way for organisations to extend the life of their fuel storage tanks ensuring they remain compliant until such time as they transition their energy mix.
Tank repairs
Following a complete inspection using leading-edge technology, we repair all varieties of above and below ground tanks and actively reduce the risk of asset failure and environmental incidents.
Our team of fully qualified, experienced welders restore tanks to safe and efficient use within the shortest timeframe possible, preventing disruption at every stage.
