Annual Tank Servicing
Maintenance of fuel storage tanks.
It is necessary to service a fuel installation in the same way that it is necessary to service a vehicle. Over the course of the year components on fuel dispensers and fuel tanks can fail, meters and gauges become inaccurate and small leaks can appear in pipework systems. The cost of a leak going unnoticed can run to tens of thousands of pounds in clean-up costs, not including fines levied on offending companies or their directors.
We address these issues by undertaking a multi part check of the whole fuel installation. This can either be done annual for low volume users or six monthly for high volume users. In view of current economic restraints Fuel Safe UK Ltd, are offering special rates for the maintenance of fuel storage equipment for various existing customers and industries.
The Elements of the annual service include:
Fuel Tanks:
- Check the fuel tank for water and sludge build up
- Check the operation of valves
- Pressure test underground product lines
- Check operation and accuracy of tank gauging systems.
Environmental Audit:
- Check compliance with current Environment Agency guidelines
- Advise of any deterioration of bund walls or other necessary components of the installation
- Recommend any appropriate new products that may provide additional protection against fuel loss.
Visual Inspection (Every 3–6 Months):
- Check the exterior of the tank for signs of rust, paint blistering, dents, or damage.
- Inspect all weld seams, fittings, lids, and vents for leaks or signs of deterioration.
- Confirm that breather valves and caps are clean and working correctly to prevent pressure build-up or vacuum collapse.
- Ensure the bund area (outer tank) is clean and free from water, debris, or fuel residue.
- Inspect pipework, hoses, and filters for wear or cracks.
Internal Inspection (Every 12–24 Months):
- Have the tank professionally inspected and cleaned to remove any build-up of sludge, rust, or water.
- Check for internal corrosion, particularly near the bottom where water may collect.
- Re-coat or treat internal surfaces if necessary using a fuel-safe protective coating.
Fuel Quality & Contamination Control:
- Only use clean, reputable fuel suppliers to prevent contaminated or water-laden deliveries.
- Regularly check for water contamination using water-detecting paste or test kits.
- Drain any water traps, filters, or sumps routinely to prevent corrosion and microbial growth.
Storage & Environmental Conditions:
- Always keep fill points, lids, and inspection covers tightly closed when not in use.
- Avoid leaving tanks partially full for long periods — a fuller tank reduces condensation build-up.
- Where possible, store tanks under cover or away from standing water and harsh environments.
- Ensure the tank remains level and securely supported to prevent strain on welds or pipework.
Servicing & Pressure Testing:
- Tanks must be pressure tested and serviced every 2–3 years, or sooner if contamination or damage is suspected.
- Any repair, modification, or welding must be carried out by Fuel Safe or an authorised technician to maintain certification.
Record Keeping:
- Keep a maintenance log recording inspection dates, servicing, and any remedial actions taken.
- Proof of maintenance may be requested if a warranty claim is made.
