90 years of floating roof technology - development and importance



From the first application until today, the most effective and economical method to reduce emissions and product losses as well as to reduce the risk of fire and explosion when storing volatile hydrocarbons above ground.

Initiated and funded by the U.S. Bureau of Mines and developed and realized by American tank construction companies, the vertical flat-bottom tank made of steel with a floating roof was created after 1920 and became the standard storage container for volatile products in the petro-industry.

Even with today's requirements, floating roof technology is always the first choice for the storage and handling of large quantities of volatile, flammable, environmentally harmful and toxic liquids.

An essential prerequisite is that the tanks are equipped with a solid floating cover and suitable sealing elements on the outer edge and on the roof ducts.

Vapors that have passed the floating roof and the edge sealing are emissions or become emissions in the case of floating roof tanks or fixed roof tanks with floating roofs.

The advantages of the floating roof:

  • Flexible use of tank space
  • Fire, explosion and implosion protection
  • Low emissions
  • High profitability
