Stored Fuel Maintenance

Is your stored diesel fuel ready for an emergency?

Failure to maintain stored fuel and storage tanks could be a disaster waiting to happen. 

Site operators rely on the continuity of their electricity supply. Because modern fuel contains lower sulphur content and significantly higher amounts of biodiesel, bacterial and fungal growth are both common in stored fuel. Microbial contamination, known as the diesel bug, is a problem that faces every substation site storing fuel. 

Contaminated fuel supplies will result in at best machinery not operating efficiently and at worst in total breakdown. Failure to regularly inspect stored fuel and storage tanks can result in emergency, mission-critical equipment failing, when you need it most.

A cost-effective solution

Andel provides a comprehensive range of oil storage maintenance services including:

Pollution prevention and compliance
