Abstract
A fluid storage tank includes a plurality of end panels defining a plurality of curved wall sections and a plurality of side panels extending between and connecting the plurality of curved wall sections. The plurality of end panels and plurality of side panels define a perimeter wall. The fluid storage tank further includes a plurality of cable arms, each of the cable arms connected to a flange of at least one of the plurality of end panels or side panels, and at least one upper tension member having a first end connected to one of the plurality of cable arms and a second end connected to another of the plurality of cable arms.
Claims19
A fluid storage tank comprising:
- a plurality of end panels defining a plurality of curved wall sections;
- a plurality of side panels extending between and connecting the plurality of curved wall sections, the plurality of end panels and plurality of side panels defining a perimeter wall;
- a plurality of cable arms, each of the cable arms connected to a flange of at least one of the plurality of end panels or at least one of the plurality of side panels;
- and
- at least one upper tension member having a first end connected to one of the plurality of cable arms and a second end connected to another of the plurality of cable arms,
- wherein the at least one upper tension member extends across an internal volume of the fluid storage tank along a plane above the plurality of side panels.
A fluid storage tank system comprising:
- a primary fluid storage tank comprising:
- a plurality of end panels defining a first plurality of curved wall sections;
- a plurality of side panels extending between and connecting the first plurality of curved wall sections, the plurality of end panels and plurality of side panels defining a first perimeter wall;
- a plurality of cable arms, each connected to an outer face of at least one of the plurality of end panels and the plurality of side panels;
- and
- at least one upper tension member having a first end connected to one of the plurality of cable arms and a second end connected to another of the plurality of cable arms;
- and
- a secondary containment tank comprising:
- a plurality of end panels defining a second plurality of curved wall sections;
- and
- a plurality of side panels extending between and connecting the second plurality of curved wall sections, the plurality of end panels and plurality of side panels defining a second perimeter wall concentrically or eccentrically surrounding the primary fluid storage tank wherein the first perimeter wall and the second perimeter wall are each obround-shape.
A method of assembling a fluid tank, comprising:
- arranging a plurality of end panels to define a plurality of curved wall sections;
- arranging a plurality of side panels extending between and connecting the plurality of curved wall sections to define a perimeter wall along with the curved wall sections;
- attaching a plurality of cable arms to at least one of the plurality of end panels and the plurality of side panels;
- attaching a first end of at least one upper tension member to a first of the plurality of cable arms;
- and
- attaching a second end of the at least one upper tension member to a second of the plurality of cable arms such that the at least one upper tension member extends across an internal volume of the fluid tank along a plane above the plurality of side panels, the second of the plurality of cable arms being attached to a different side panel than the first of the plurality of cable arms.
