DP Fuel Tank Services (DP-FTS) and Fuel Hygiene Solutions (FHS) successfully collaborated recently on the replacement of an old petrol pump, thereby making the underground storage tank fit for re-use.
Before installing a brand-new pump with DP & FHS livery, the old pump was in a uniquely good condition for a 1960’s dispenser, which had spent its life on a country home estate serving the working farm. The Tokheim pump has now been carefully transported to a renovation company in Devon, where it will be brought back to its fully restored glory. DP currently have two vintage restored petrol pumps; a 1920’s hand crank Godwin in Cleveland Discoll livery and a 1950’s Avery Hardoll in Gulf livery. Nigel Plumb, Director said; “Our fully restored petrol pumps are a great reminder of the rich petroleum history in the UK”. Back on the farm DP carefully removed the Tokheim pump; nitrogen gas inerted
the underground fuel storage tank, manually cleaned and gas-freed the tank internally, and carried out ultrasonic testing to ensure the future integrity of the tank. Then FHS joined the project to relocate the dispenser, freeing up valuable space, and installing a full ATEX approved pump along with industry
certified Smartflex pipework. Our brand new dispenser was ready for use.
Merry Christmas and Happy New Year to all our customers and everyone we have worked with in 2017, we look forward to seeing you all again in 2018. We will have lots of exciting news in the New Year, so watch this space.

It transpires that Las Vegas gunman Stephen Paddock fired “incendiary” bullets in an attempt to explode a tank of jet fuel in his attack on concertgoers at a country music festival. Paddock, 64, fired the special ammunition – meant to ignite upon contact – at a 43,000-barrel fuel tank at the McCarran International Airport near the festival.
The rounds were recovered in Paddock’s room at the Mandalay Bay Resort and Casino. Airport officials confirmed that two rounds did hit a tank of jet fuel, with one actually penetrating the tank, but did not confirm that these were incendiary rounds.
Officials last week downplayed the possibility of any explosion triggered by gunfire, given designs meant to withstand brief exposure to flame.
Crime Scene Investigators also found “tracer” rounds in the hotel, which are used to illuminate the path of the bullet and improve accuracy in low visibility.
But the plot was doomed to failure from the start as Jet fuel is relatively hard to ignite burning at between 800 and 1,500 degrees Fahrenheit. Mike Boyd, an aviation analyst for Colorado-based Boyd Group International, said “I used to train hazardous-material instructors at airports, and one of the things we taught was that if you even if took a blowtorch to a bucket of standing jet fuel, it would take about 90 seconds for it to want to burn,” Boyd said.
In addition, jet fuel requires a massive ratio of fuel to air for even its flammable vapour to combust. To ignite 17 ounces of jet fuel, for example, it would have to be atomised, (mixed in) with 1,000 ounces of air.”
The new twist on the mass shooting may highlight some vulnerabilities of airport fuel tanks, which often stand out in the open with little or nothing to shield or conceal them, but it also reinforces why they’re aren’t necessarily a security priority, Boyd said.
“They just aren’t good targets for terrorism,” he said.
DP Tanks had the task of digging out a redundant petrol tank for West Surrey Golf Club in Godalming, which involved the removal of a 4,500 litre UST redundant petrol tank from the ground in preparation for future building work on the site where the petrol tank was located.
The DP Tanks team inerted the tank using nitrogen gas and gave it a comprehensive internal clean prior to excavation from the ground.
The excavation was checked for contaminants and backfilled using clean materials, and finally, the tank and associated pipework were removed and taken off-site for recycling.
Safely Removing Fuel Tanks
Removing a tank is not just a matter of undoing a few rusty bolts and lifting it onto the back of a lorry. It has then to be cleaned thoroughly first so that the tank can be transported safely and recycled.
The tanks have often been built in almost inaccessible basement rooms. Sometimes they are completely bricked up to provide a bund* in case of leaks, with just a small inspection hatch being left.
Bunding, also called a bund wall, is a constructed retaining wall around storage “where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as remedial action can be taken. Bunding is a legal requirement in many countries particularly around tanks, storage vessels and other plant that contain liquids which may be dangerous or hazardous to the environment
Particular examples which receive specific attention in the UK, the rest of Europe and the USA are oil and fuel storage tanks and transformers at electricity sub-stations which are filled with oil for cooling and insulation purposes.It is reasonably easy to construct a “water-tight” bund around the base of a tank or vessel. A concrete base and a sealed wall of masonry, brickwork, concrete or even prefabricated steel provide the holding capacity.
In the UK commercial installations exceeding 200 litres and domestic installations exceeding 2500 litres require a bunded tank to comply with Environment Agency ‘control of pollution regulations’.
On occasions, during the tank removal process, we have to cut up the tanks on the spot and manhandle the pieces out through a maze of corridors, stairs and doors, without damaging anything on the way out.
DP Tanks have used this technique successfully in many high profile jobs, including Buckingham Palace and a number of prestigious London hotels.
