<p>This invention relates to a method on tensioning a flexible floating cover for a liquid storage reservoir wherein the surface level of the stored liquid varies. A peripheral envelope formed at least adjacent a portion of the peripheral edges of the floatable cover is adapted to be inflated with a compressible fluid, such as air, for proper tensioning of the cover as the level of the stored liquid varies in the reservoir and for preventing wrinkling of the cover.</p> |
