There is a annular space with seal gland between the floating roof and the tank wall to separate air when stored liquid float up or down on the roof greatly reducing evaporation loss in the storage process.
Over the years jm dixon associates has undertaken the design of many floating roofs both double and single deck for world renowned clients such as philips 66 exxon mobil and ineos.
The annular pontoon is divided into several chambers by radial bulkheads.
Doorsheet is a minimum of 8 high x 8 6 wide.

These include new builds together with the evaluation of existing roof designs for suitability such as analysing the various flotation cases and repair.
