ABSTRACT:
A floating roof for a liquid storage tank has a lid structure comprising a plurality of fluid tight interconnected plates of fluid tight material and a plurality of buoys for imparting buoyancy to the lid structure arranged on the surface of the lid which is opposite the surface of the lid which faces the liquid body upon which the lid floats. Each buoy of at least a majority of the buoys has a base formed of one of said plates, and further includes structure attached to the base and having at least two sides inclined relative to a perpendicular plane through the lid structure and relative to each other.
A similar floating roof for a liquid storage tank has again a lid structure and a plurality of buoys on the upper surface thereof. These buoys include shells having portions spaced from the lid structure, and parts for supporting the lid structure during advanced diminution of the liquid level are attached to the spaced shell portions of at least a majority of the buoys and to other portions of the floating roof, and extend through the latter buoys.
In each embodiment at least a majority of said plurality of buoys has a length greater than its width, and a width greater than its height, to effect a relatively long and stiff low silhouette, thereby imparting stiffening to the interconnections paralleling the longest buoy dimension between the plate which forms the base of the buoy and adjacent plates.
