Self Bunded Tanks VS Single Skin Cylindrical Tanks

The DANGERS and DIS-ADVANTAGES of a Single Skin Cylindrical Tank:

Non-Compliant Cylindrical tanks with no bund wall and ground contamination

The above image is an all to common site of a tanks with extreme environmental contamination. These installations does not comply to the regulations and is dangerous to the employees. It is also permanent fixtures, expensive to build and cannot be re-located easily if needed.

  • These single skin fuel storage tanks are not safe or environmentally friendly!
  • They should stand in a fixed bunded area – any leak will soak into the soil and contaminate.
  • With full exposure to the elements, tank integrity and durability is compromised.
  • They are semi-permanent – expensive and time consuming to re-locate if necessary.

    What is a Self Bunded Tank?

    A Self Bunded Tank (also called a Double Wall Tank) is a Tank within a Tank. The Inner Tank will serve as the Storage Tank and the Outer Tank will serve as the Bund Area. This means that a permanent built bunded area is no longer necessary. The Bunded area will hold 110% of the Inner Tanks volume.
