Design and fabrication of fuel and petroleum product storage tanks

Fuel storage tanks hold petroleum products such as gasoline, diesel and fuel oil at industrial and refinery scale. The tank type (fixed roof or floating roof) is chosen by the product's vapour pressure and volatility.

Technical details

Besides structural calculations, the design of these tanks must cover safety requirements such as bund walls, fire-fighting systems, lightning protection and safe spacing between tanks.

Behineh Ab designs and builds fuel storage tanks for refineries, fuel terminals and petrochemical plants; for more detail, see our pages on fixed-roof tanks, floating-roof tanks and oil tanks.

Types of fuel tank: fixed roof, floating roof, underground

A fixed-roof tank is the most economical option for low-volatility products such as diesel and fuel oil. A floating-roof tank noticeably cuts evaporation losses for volatile products such as gasoline. Underground tanks are used mainly at filling stations because of limited space and urban safety rules.

HSE safety requirements for fuel tanks

Because of the risk of fire and explosion, fuel tanks have stricter safety requirements than most other tanks: an earthing system to discharge static electricity, a bund wall to contain spills, safe distances from other equipment and buildings, and in many cases a fixed or semi-fixed fire-fighting system.

Choosing fuel tank capacity and layout

Fuel tank capacity should be set from daily consumption, the resupply interval and a safety margin, not just the space available on site. A group of tanks side by side (a tank farm) must also keep standard safety distances so that, in an incident, the risk of spreading to neighbouring tanks is minimised.
