Tank Base Clean

In almost any fuel tank, where product is stored for any length of time, contamination builds up. This contamination is often water based and absorbed from the moisture in the surrounding atmosphere. The specific nature of the fuel, the operating environment, temperature and weather will all determine how much contamination forms in the tank, but more than 90% of the contaminants will be found in the bottom 10% of the tank.

This is usually a mixture of water and an oily organic sludge, known as diesel bug, and if it reaches the fuel lines and filters will almost certainly cause a engine or boiler failure. One cheap, simple and effective way to reduce the risk of failure is to drain the bottom of the tank on a regular basis. The waste produced can then be removed from site and disposed of in an Environmental Agency permitted location.

Craggs Environmental has a sophisticated range of tankers and pump vehicles which can safely and cleanly remove these contaminates from site and provide the legally required waste certification documentation.

Contamination Testing and Spill Management

Ground fuel contamination, be that from a spillage or leakage from a tank or fuel lines, can be a very expensive and lengthy issue to resolve if not managed with the appropriate levels of skills, expertise and equipment. At a time where speed of response is critical, Craggs Environmental’s 24 hour Emergency Helpline is there to provide access to a range of emergency response services.

Should you have suspicion of contaminated fuel, Craggs Environmental can test and return results quickly and remove the contaminated fuel if the results are of high level risk.

On Site Fuel Cleaning

Having removed the free standing contamination with a Base Clean, in higher risk environments such as emergency standby generators, it may also be necessary to remove suspended water and particulate matter by a process of fuel filtration and treatment. Due to the costs of moving the fuel, the most economical way to undertake this process is to bring the fuel filtration system to customer site and undertake the full operation within vicinity of the storage tank.

Craggs Environmental has a range of filtration systems which can filter from 3,000 up to 300,000 litres in one day. Pricing is based upon the volume of fuel to be filtered and the levels of contamination seen when the fuel is tested. The resulting fuel is filtered down to a level of 1 micron, and water levels can be taken to well below the British Standard 200 parts per million measure.

Fuel Additive

Particularly important if the fuel is to be stored for any length of time (more than a couple of months) and essential if the fuel is used in any type of critical application such as emergency standby generation. Craggs Environment provides a wide range of fuel types and additives specifically designed to ensure that the fuel is always available and of the right quality for the particular application.

This includes fuel stabilisers for long term storage, anti-waxing additives for winter applications and fuel clean burn additives to protect against excessive engine and boiler damage.

Fuel Uplift & Transfer

In a number of circumstances, either because the customer no longer has need for a particular fuel, or because the fuel is no longer of the quality required for the particular application, Craggs Environmental is able to uplift the fuel with a range of tankers from a single 1,000 litre IBC, through a range of rigid tankers up to a fleet of 40,000 litre articulated tankers.

Depending on the quality of the fuel, Craggs Environmental will charge for disposal, or where the fuel quality is higher, a rebate may be available if the fuel can be reused in a different application.

Fuel Store Remote Monitoring

Traditional methods of monitoring fuel levels require trained staff to be onsite and available to continually monitor usage and, if the skills are available, quality of the fuel. Advances in technology now allow for a range of remote monitoring of both quantity and quality of fuel at price points which run from domestic scale through to full industrial installations.

Fuel Tank Installation, Removal, Inspection & Cleaning

Commercial fuel tanks, typically fabricated in steel, are tough and long lasting. However, from time to time, they will require a full inspection for weaknesses caused by cracks or erosion, usually from rust. For industrial fuel storage tanks within the fuel industry, 5 years is the generally accepted inspection period. It is also highly recommended that a regular regime of tank cleaning is undertaken.

This tends to be on a two year cycle, but depending on the nature of the fuel usage, it may be longer or shorter.

Fuel Lifecycle Managed Service

All of the services that have been described are offered individually on an ad hoc basis. However, many customers prefer to contract arrange of services wrapped into an annual fixed contract. Craggs Environmental is able to offer such a contract, which is completely bespoke and tailored to your individual needs.
