External Floating Roof Tank Pontoon

Pontoon type floating roofs are the most economical type of floating roofs in the market.

External floating roof tank pontoon.

Beside ergil storagetech floating roof s economic benefits they also protect the environment by not releasing toxic gasses to the atmosphere. Sketches are provided in the article depicting the pan type pontoon and double deck arrangement for external floating roof tanks. The roof rises and falls with the liquid level in the tank. The low single deck is the more efficient of the two for 30 to 170 foot diameter tanks.

Ergil storagetech internal floating roofs which minimize the evaporation losses of stored products such as jet fuels gasoline diesel and crude oil can be supplied as aluminium or stainless steel. In principle this eliminates tank breathing loss and greatly reduces the evaporative lo. Double deck pontoon roofs which are designed with concentric annular pontoons with radial bulkheads in each pontoon section. The two preferred configurations for external floating roofs are the double deck and the low single deck with 30 minimum pontoon area.

The sketches shown illustrate the above single deck and double deck floating roof with the critical components for these structures. Diameter to store crude oil. The pontoons in floating roof tanks play an essential role when it comes to performance in above ground storage tanks. As opposed to a fixed roof tank there is no vapor space in the floating roof tank.

It consists of an open topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. Roof designs shown have been used in tanks as large as 345 ft. An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. At matrix applied technologies we custom engineer our heavy duty pontoon internal floating roofs to meet the most demanding environments even regions where earthquakes are likely to occur or where an aboveground storage.

In my humble opinion the double deck arrangement would be a more robust design but may cost extra and a detailed techno economic evaluation would be needed to arrive at the optimum option.
