Abstract
A floating roof for floating on and covering a liquid product stored in a tank, comprises a substantially flat, planar deck having a seal fixed to the periphery thereof and engaged with an inner wall surface of the tank, and a plurality of separate and independent buoy units secured on the deck to provide uniform buoyant support for the roof in the event of leakage of stored product onto the upper surface of the deck, said buoy units arranged such that lines drawn between the centers of any three adjacent units form a substantially equilateral triangle, and all of the buoy units together having a buoyancy at least as great as the total weight of the roof.
