Storage tank containment system
A tank is used in the containment, transport, and/or storage of fluids, e.g., one or more liquids and/or gases. In one embodiment, the tank includes a plurality of segments collectively defining an interior chamber that retains the fluid(s), each of which includes opposing ends defining beveled mating surfaces. The tank also includes a plurality of endcaps positioned between, and in engagement with, adjacent segments, as well as a plurality of webs that include a series of first webs having a first configuration and a series of second webs having a second, different configuration. The first webs are positioned within the plurality of segments between the ends thereof, and the second webs are positioned within the endcaps. In an alternate embodiment, the tank is devoid of the endcaps, and instead, includes segments defining beveled mating surfaces that intersect at junctures to define four corner sections of the tank.
1. A tank comprising:
a plurality of segments each including opposing ends defining beveled mating surfaces, wherein engagement of the beveled mating surfaces of adjacent segments defines corner sections including junctures;
a plurality of first webs having a first configuration, the first webs being positioned within the plurality of segments between the opposing ends thereof; and
a plurality of second webs having a second, different configuration, the second webs being positioned in the corner sections adjacent the junctures.
2. The tank of claim 1 , wherein the first webs are approximately annular in configuration and the second webs are approximately elliptical in configuration.
3. The tank of claim 2 , wherein the segments each define a length extending along a longitudinal axis, the beveled mating surfaces extending at an angle of approximately 45° in relation to the longitudinal axis.
4. The tank of claim 3 , wherein the plurality of segments include a first pair of segments each defining a first length and a second pair of segments each defining a second length, and wherein the first and second lengths are approximately equal such that the tank defines an approximately square-shaped transverse cross-sectional configuration.
5. The tank of claim 3 , wherein the plurality of segments include a first pair of segments each defining a first length and a second pair of segments each defining a second length, and wherein the second length is greater than the first length such that the tank defines an approximately rectangular transverse cross-sectional configuration.
6. The tank of claim 1 , further comprising upper and lower closure plates, the closure plates being positioned between the plurality of segments and separated by a vertical distance, the closure plates and the plurality of segments defining an enclosed cavity configured and dimensioned to retain boil-off-gas therein.
7. The tank of claim 1 , wherein each segment defines a midpoint, the tank being configured such that each of the midpoints lies in a single geometric plane.
