Because the flexible floating roof deck can float up and down to close to the liquid level gas space above the liquid level can be greatly reduced thereby greatly reducing the evaporation.

An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate.
It consists of an open topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid.

External floating roof and internal floating roof.
The roof rises and falls with the liquid level in the tank.
This type of tanks used for 2 main reasons.
Minimize the loss of the stored liquid product inside the tank due to evaporation.
Storagetech storage tank internal floating roofs storagetech has been proudly innovating designing manufactiring and installing external and internal pon.
As the liquid level changes due to filling emptying contraction and expansion the roof is designed to move with the liquid.

Floating roof tanks are commonly protected against lightning ignition by bonding the floating roof to the seal shoes at no less than 3m 10ft intervals use of insulating sections in the hanging linkages covering sharp points on hangers with insulating materials and installation of electrical bond straps across each pinned hanger joint.
