A clip for securing one or more cover panels within a containment structure includes an annular portion partially-enclosing an internal space and two compressible legs adjoining opposite ends of the central portion. The clip further includes a clasp with first and second securing tabs configured to fixedly secure an object within the internal space and apply an outward force on the compressible legs.

Present invention relates to the field of a storage tank design and can be used in the construction of tanks for storing light ends and, preferably, for storing gasoline. The claimed tank for storing petroleum products consists of a body, a roof and a floating protective cover comprised of a plurality of floating elements in the form of solids of revolution having the same shape. In the tank, a portion of the floating elements of the protective cover is situated below the surface of the liquid, and a portion is situated in the gas space of the tank. The distinguishing feature of the proposed invention is the floating elements, which differ from one another in shape and size by not more than 5%. Furthermore, the floating elements that make up the floating protective cover have a centre of flotation that is offset from their geometric centre. All of the elements of the protective cover are made of non-sparking metal. The technical result of the invention is that of reducing the rate of evaporation of the liquid and the concentration of vapors, suppressing the process of combustion and preventing the possibility of electrostatic buildup and spark discharge between the floating elements.

A reservoir shading structure made of multiple consumer beverage containers. The containers each have a bottle portion, and a top portion preferably with a collar. The top portion is removed, inverted, and replaced in the bottle portion to extend into the bottle portion. The top portion is hermetically sealed to the bottle portion and a cap is welded into the top portion to hermetically seal the consumer beverage container. The consumer beverage containers are UV resistant, made of NSF/ANSI Rule 61 compliant material, and may include carbon black in their construction. Multiple consumer beverage containers are placed in a uniform layer across the surface of the reservoir to form a shading structure that reduces evaporation and microbial growth.

A liquid containment structure such as a frac pond has a perimeter wall; a floor liner bounded by the perimeter wall; and a platform underneath the floor liner, the platform formed of a plurality of mats laid edge to edge and whose upper faces collectively define a support surface. Related methods are disclosed.

A flexible fluid storage tank and method for assembling said tank, with specific emphasis on a system that may be easily road transported and field assembled with little or no tools, while preserving the flexibility of being tailored in size, shape and configuration to the user's needs with minimal customization and disassembly capabilities.

The present invention relates to a self filling cover device for covering a surface of a liquid, having a shell (2) defining inner cavity, and the inner cavity is to be filled at least partly with liquid, so that the inner cavity is divided in at least two chambers (3,4) by a separating means (5,51,52), and one of the chambers (4) is provided by at least one opening (6) formed in the shell (2).

Cover element for forming a floating covering for a liquid tank, comprising a housing (1a, 1b) having a first longitudinal coupling profile (2) and a second longitudinal coupling profile (3), as a result of which two adjacent housings (1 a, 1 b) may be coupled to one another by means of hook hinge profiles (2a, 3a) at the bottom and top coupling profiles (2b, 3b) and a locking profile (7). The end faces of the housings (1a, 1c) are provided with a transverse coupling profile (10) which is configured to cooperate with a sliding coupling profile (9) which is slid over the transverse coupling profiles of both adjacent housings. In this configuration, the cover elements are coupled to one another by a coupling construction that does not protrude beyond the main planes (4a, 4b) of the cover elements, as a result of which the surface of the entire floating roof is smooth, resulting in a substantial reduction in the accumulation of dirt etc. on the roof due to the absence of the vertical coupling flanges.
