ABSTRACT:
A floating cover or roof having a plurality of floating panels or panels is provided. The floating cover disposed in a storage tank includes a frame having a plurality of openings, the floating panels mounted into the respective openings, an inspection port formed on an upper member of the floating panel and communicated with an inside of the floating panel. The inspection port provides for inspection for the presence of moisture, vapor, and condensate trapped in the inside of each of the floating panels without disassembly of adjacent floating panels, and also provides for the replacement of a damaged or degraded one among the floating panels without taking the internal floating roof out of the storage tank.
