Our Floating Roof Tank Fabrication & Construction Capabilities

T BAILEY, INC.’s fabrication facilities can scale production to accommodate any size of floating roof tank. Our capabilities include: 

When it comes to floating roof styles, we can fabricate single or double deck floating roofs and can install IFRs and EFRs made from aluminum, steel, or fiberglass.


What Is A Floating Roof Tank? 

Floating roof tanks are typically large, field-erected steel petroleum tanks, equipped with a platform (roof) which floats on the surface of the tank’s product. The floating roof rises and falls as petroleum product is withdrawn or added to the tank. 

There are two types of floating roof tanks: 

  1. External floating roof tank (EFR): the floating roof is all that separates the product from the elements. In this case, the floating roof serves as the literal roof for the tank. 
  2. Internal floating roof tank (IFR): in addition to being equipped with a floating platform, IFRs are also covered by a traditional steel roof. 


What are the advantages of installing a floating roof tank? 

The primary advantage of installing an EFR or IFR is vapor control. These tanks excel at reducing the emission of volatile organic compounds (VOCs) and other negative air pollutants. 

Additionally, floating roof tanks provide economic advantages by limiting product loss. And because floating roofs rest directly on the product, they also reduce vapor space, resulting in a lower risk of rim space fire. 

Overall, the purpose of a floating roof tank is to mitigate the impact of petroleum products on the environment, to reduce the risk of product loss, and to improve safety. 


What are the disadvantages of floating roof tanks? 

The primary risk associated with floating roof tanks is that rainwater and snow can accumulate on the roof, causing the roof to sink into the product if its drainage systems aren’t functioning properly. This is only a risk for EFR tanks, as IFR tanks are covered by a traditional steel roof and are thus protected from the elements. 

At T BAILEY, INC., we ensure that our EFRs are built to API Standard 650 (Appendix C) specifications, which stipulate that floating roofs must be designed to withstand up to a 24 hour 10” (255mm) rain event. When joined with effective drainage systems and regular maintenance, our EFR tanks are robust and can withstand all the weather conditions of the rainy Northwest.
