units enabling multi product dispensing (diesel and gas oil) from a single location. Multi-compartment tanks with automatic cross feeds are often recommended for high capacity/turnover applications. Cross feeds are designed to ensure that dispensers are always drawing fuel from the earliest stock delivery. For biofuels or other more challenging fuel products, tanks can be equipped with temperature controlled fuel conditioning, using filtration and a recirculation pump to ensure that the fuel quality is maintained irrespective of the ambient conditions.

CUSTOM E R S TOR IE S Gravesham Borough Council (GBC) has decommissioned the last of its underground fuel storage tanks following a strategic review of its depot fuelling facilities. Fuel is now being dispensed from a dual compartment tank package, providing 30K – 5k litres capacity for diesel and gas oil, respectively. “After twelve months in service we have achieved significant savings in cost in terms of convenience, maintenance and administration,” says transport manager, Ronnie Helen “An important advantage of an above ground tank is that fresh supplies have to be metered-in as opposed to loading underground tanks by gravity feed. Metering eliminates any possibilities for discrepancies and we now have absolute reconciliation of our fuel stocks.” The GBC installation comprises of a standard tank with electronic monitoring for tank contents and dispensing. Data from these transactions are uploaded to a web-based fuel management service.

THE LEDBURY PREMIUM & STANDARD The simplified build standard allows greater scope in pricing for all tanks up to 220,000 litres capacity. The main difference between the Premium and the Standard are the choice of either top suction outlets or gravity feed requirements. Installation of above ground tanks is usually fairly straight forward. All that is required is a suitable plinth and a properly drained hardstanding for vehicles. As a tank supplier, LWE works in collaboration with all the frontline suppliers of pump dispensers and fuel stock management services. The company can provide impartial advice on security and fuel usage monitoring. Alternatively LWE will work with the customer to integrate these services within an existing fuel management infrastructure.

Stainless Steel Bunded Tanks For process chemicals and other potentially corrosive wetstock products, such as de-icing fluid LWE has supplied bunded tanks made of stainless steel. Apart from seals and the sheet metal specifications, these are identical to standard bunded tanks. The company’s comprehensive manufacturing facilities, include specialised steel welding equipment required to meet all these requirements. LWE also has the expertise to undertake responsibility for the delivery of a complete stock management solution including pump filling and dispensing controls.

AdBlue Tanks AdBlue is now being dispensed alongside diesel fuelling facilities at most commercial transport depots and truck stops. It is also being introduced onto retail forecourts and its application is expected to grow as clean air regulations are extended to cover diesel powered taxis and light service vans. As a chemical urea product, tanks designed for the storage for AdBlue have either a plastic, or stainless steel internal skin. LWE can provide integrated AdBlue tanks as part of a Diesel /Gas Oil/Lubrication Oil multicompartment configuration all contained within a single bund to minimise the overall foot print area. Apart from functional design considerations, AdBlue storage tanks are common to other bunded stainless steel tanks produced by LWE. Capacities start from 2,500 litres and tanks can be supplied as standalone installations complete with pump dispensers and contents gauging.

Bespoke Requirements

As all LWE tanks are built to order, each individual design can be manufactured to suit almost any bespoke needs. Current production includes this 178,000 litre capacity tank, destined for a water treatment facility. Design features include the use of external bracing for structural integrity and to allow seamless internal coating.

Multi Compartment tanks LWE have in recent years manufactured and installed an ever increasing number of multi compartment tanks. This allows a multi functional site the ability to house its core products within one bunded unit. Typical products could be White Diesel/Gas Oil and AdBlue, often with a small Engine Oil compartment. The number of products or compartments can be tailored to suit the individual client needs.

Petrol Storage Above Ground SuperVault MH Underground storage of highly flammable products such as methanol or petrol was once considered the norm due to the limitations of existing above ground tank manufacturing technology. Today however, the enabling technology has progressed significantly, allowing users to take advantage of the benefits of using above ground tanks for bulk storage. Easily re-positioned above ground tanks offer greater flexibility, but most importantly, above ground storage is now considered essential in environmentally sensitive

The design incorporates secondary containment, with two concentric skins of steel separated by 150 mm of specially formulated insulating concrete. The interstitial space can be monitored continually for leaks, a provision which obviates the need for any additional bund protection. SuperVault tanks can be configured as multi-product storage units for capacities up to 110,000 litres. From an operational point of view, above ground tanks need very little site preparation, they can be delivered as complete packages incorporating pump dispensing, data telemetry and electronic wet-stock management facilities.

areas and wherever there is a potential risk of flooding. As a licensed manufacturer of the SuperVault MH, LWE has supplied over 130 installations throughout the UK, accounting for more than three million litres of storage capacity. The SuperVault’s unique performance specification of a four-hour fire rating together with its multi hazard accreditation, puts it at the forefront of tank safety technology.

CUS TOM E R S TOR IE S West Falklands Fuelling Facilities An LWE petrol storage tank has been installed at Fox Bay Village, West Falkland, a remote trading station at the southern end of the Falkland Sound. The contract was awarded by Stanley Services Ltd, which provides fuel to both the Domestic population of the Falkland Islands and the fishing fleet operating in the waters near and around the Islands.

“This new facility will allow our customers on West Falkland to collect petrol in a very straightforward and easy manner and saves them having to store highly inflammable product in 205 litre barrels,” noted Tom Swales, Managing Director of Stanley Services Limited. The new tank will provide above ground storage of 10,000 litres capacity for petroleum spirit. It will be located alongside existing storage facilities for diesel. The package includes fuel dispensing pumps and an electronic metering system which allows registered customers to obtain their fuel by way of a self –service account.

Bunded Fuel Storage For Marine Environments Waterside and floating re-fuelling facilities are some of the most challenging locations, for potential risks of pollution to the natural environment as well as the need to withstand corrosive seaside weather conditions. For servicing and tanker access, fuel storage tanks are usually based on the harbour side with delivery pipelines extending out to the pump dispensers on the fuelling pontoon. Clearly self-bunded above ground tanks are most suited for such applications. True secondary containment ensures safe operation under all circumstances and satisfies the necessary regulatory and environmental requirements. This includes Class 1 leak detection monitoring for petroleum. LWE has significant experience in the installation of waterside fuelling facilities and will be happy to provide advice on new installations.

Service Modules Lube Oil, Waste Oil Tanks manufactured by LWE, are usually custom built within the company’s design principles. This means that LWE can adapt any of these principles to accommodate virtually any storage requirement. Service modules can incorporate lubrication oil storage/dispensing, compressed air, pressure washing and hand washing facilities. Tanks are also supplied for the safe handling of waste oil/ contaminated diesel/petroleum. Integral bunds are incorporated as necessary. Rectangular tanks and bunds can be configured as either single of double skin according to requirements. Build quality is guided by the appropriate British standards. The majority of tanks built today, require installation within a sealed bund to achieve acceptance by the UK’s Environmental Agency. 11
