BUOYANCY VESSEL INTERNAL FLOATING ROOF

The buoyancy tank style internal floating roof use the structure of tank that the main part of the IFR is tank shape.The main part contacts the liquid fully. There is nearly no oil gas space that it could greatly reduce the evaporation loss of the liquid.

The whole buoyancy tank internal floating roof is made of many small buoyancy tank, so the buoyancy is much more bigger than the normal internal floating roof. The thickness of the whole IFR is less than the pontoons style IFR which improved the storage capacity of the oil tank.
