Floating roof tank
A floating roof for use in a storage tank has an upstanding substantially cylindrical shell. The floating roof comprises a number of inner roof sections substantially identical one to the other and individually buoyant. Each of the inner roof sections includes a pair of upstanding generally parallel side walls and a pair of upstanding generally parallel end walls joined to form a first continuous peripheral wall. A first bottom wall closes the area defined by the first peripheral wall. The first bottom wall has portions spaced upward from the lower edges of the side walls and the end walls which define a number of downwardly opening pockets to trap vapors in the space provided and to increase the stability of the inner roof section during flotation. Sealing means supported upon the roof sections and disposed between the roof sections and the associated shell provide a vapor seal between the floating roof and the associated shell.
