Fuel Uplift & Transfer

Due to the nature of Gas Oil (Red Diesel) and its many applications, there is often a regular requirement from many customers to either uplift fuel from their tanks or remove the fuel, or to uplift the fuel and transfer to either other tanks on site, or to move to an alternative site.

For fuel removal (where it is not transferred to another customers site) depending on the quality of the fuel, this service is chargeable for fuel that is of waste standard. If the fuel is of a higher quality, Craggs Environmental will be able to offer a rebate against the uplifted fuel, assuming it has a resale value.

There are a number of reasons that the fuel may require removal or transfer:

  1. Fuel is redundant due to change in customer requirements
  2. Fuel is badly contaminated and cannot be cleaned on site
  3. Fuel is no longer of high enough quality for required application (for example standby power generation)
  4. Tank is required for cleaning or maintenance
  5. Tank is damaged and leaking

Craggs Environmental has uplifted over 4,500,000 litres of redundant fuel

To be of significant value, the fuel will need to be within, or very close, to ISO and British Standards for refinery grade fuel. Under the Craggs Environmental fuel quality scale, detailed below, this would equate to grades 1 and 2.

If the fuel quality is around grade 3, there will be a lower rebate value available for customers who wish to have the fuel removed and finally, below grade 3, where the fuel is likely to be classified as waste, there will usually be a charge to remove and dispose of the waste fuel.

Craggs Environmental has a large fleet of tankers capable of uplifting and transferring volumes from small 1000 litre IBC tanks, through to full 40,000 litre articulated vehicles for the largest uplifts anywhere across the UK (including most Islands).

These services can be provided on an ad hoc basis, where a customer has a specific requirement, or can be provided as part of a more regular Fuel Management Service, in which the responsibility of testing, monitoring, cleaning and transferring fuel is provided on a fixed price annual basis.

In this case, Craggs Environmental takes full responsibility for ensuring that the right levels of fuel at the correct quality are in the right tanks – giving customers confidence that fuel quality or quantity will never be a risk to the business or public service involved.

54% of customers who had their fuel sampled had
fuel which was outside of specification

Craggs Environmental has designed a methodology to categorise fuels into 5 standard grades, based upon a range of factors which can be tested. This simple, but very effective approach helps customers to make sensible decisions as to what quality of fuel is acceptable for the various applications each site might require.

Craggs Environmental Stored Fuel Categorisation

Quality Characteristics Appearance
Grade 1 Quality: Grade 1
  • Refinery quality fuel
  • Fully specified ISO and British Standard quality
  • Cherry Red in colour
  • Water below 100 ppm
  • No visible particulate
  • Cetane Level 45
  • Starts to degrade almost immediately fuel is stored in tank
  • Maximum shelf life of around 6 months at this grade
  • Can be used for any Gas Oil requirement
Grade 2 Quality: Grade 2
  • Stored fuel (more than 6 months)
  • Slight darkening in colour from particulate contamination
  • Still within ISO and BS quality
  • Water levels below 200ppm
  • Maximum shelf life of 18 months at this grade, assuming additive
  • Can be used for any Gas Oil requirement
Grade 3 Quality: Grade 3
  • Stored Fuel (more than 18 months)
  • May fall outside of Gas Oil standards
  • Water levels may be above 200ppm
  • Fuel darker red from higher particulate content
  • Possible small quantities of visible particle contamination or free water at bottom of sample
  • Not recommended for any use in critical environment or in combustion engine (Generator etc)
  • Flash point levels likely to be reduced, hence higher chance of “dirty burning” carbon build up
  • Still generally usable for boiler / heating applications
  • Fuel polishing can bring the fuel back to Grade 2 and within ISO standards
Grade 4 Quality: Grade 4
  • Long term stored fuel
  • Much darker colouring of fuel from particle contamination
  • Likely to see levels of both fungal contamination and free water at bottom of sample
  • Sample likely to be slightly cloudy, due to water particles suspended in fuel
  • Will cause significant damage and likely failure in critical applications
  • Likely to cause filter clogging issues for heating or boiler applications
  • Fuel polishing may be able to bring fuel to Grade 2 (depending on levels of degradation)
Grade 5 Quality: Grade 5
  • Very long term stored fuel
  • High visible contamination
  • More “grey” than “red” in colour
  • Should be consigned as waste
  • Unlikely suitable for fuel polishing
  • Often found at very bottom of tanks with cleaner fuel above
  • Should never be used as Gas Oil, will damage boiler and cause failure
