Fluid storage tank for fracking fluids
Disclosed is a tank that retains a large amount of fluid in a safe manner. The tank can be easily and rapidly constructed and disassembled for subsequent use. A liner has lifting straps that are lifted by winch booms connected to booms. Exterior securing straps are used to hold the liner in place. Connecting plates are secured to trunnions on each of the panels. Pressure pins allow the connector plates to flex so that the panels can form a round or oval tank. The panels are constructed in a curved fashion to create the round or oval tank wall.
1 . A method of storing fluid comprising:
forming a tank wall with curved steel panels by connecting said steel panels with connector plates;
placing a manifold that is recessed in ground below said tank wall so that outer ports and manifold valves are located outside of said tank wall and inner ports are located inside said tank wall;
placing a liner inside said tank wall using at least two booms that attach cables to a plurality of lifting straps located on an inner portion of said liner;
attaching said inner ports to said liner with watertight gaskets so that an inner portion of said liner is connected to said outer ports allowing said fluid to be filled and drained in said tank;
using a winch on said at least two booms to simultaneously lift said liner on said tank wall so that at least one section of said liner extends over a top portion of said tank wall;
attaching securing straps on said liner to an outer portion of said tank wall to secure said liner to said tank wall.
2 . The method of claim 1 :
wherein said method of placing said manifold comprises placing said manifold so that said outer ports comprise at least two ports with each of said two ports having a valve;
and further comprising:
inserting water in said tank through at least one of said two ports; and
inserting fracking chemicals in said tank through at least another of said at least two ports.
3 . The method of claim 1 further comprising:
forming an opening in said liner that aligns with a manway in one of said curved steel panels when said liner is placed inside said tank wall;
sealing said liner to said manway;
placing a watertight door on said manway.
4 . A method of storing fluid comprising:
assembling a tank wall comprising:
providing a plurality of curved steel panels with each of said curved steel panels having a panel box located at the center of gravity of each of said curved steel panels;
transporting each of said curved steel panels with a boom so that each of said curved steel panels are arranged in a circular shape;
connecting each of said curved steel panels with connector plates;
securing said connector plates to said curved steel panels by inserting pins through trunnions that protrude from said curved steel panels and through apertures in said connector plates;
attaching a liner to said tank wall comprising:
connecting lifting straps located on said liner to spreader bars carried by cables that are attached to winch booms;
pulling sides of said liner up along sides of said tank wall using said lifting straps attached to said spreader bars by activating said winch booms;
attaching said liner to an exterior surface of said tank wall with securing straps located on said liner;
placing a manifold that is recessed in the ground below said tank wall so that outer ports and manifold valves are located outside of said tank wall and inner ports are located inside said tank wall;
attaching said inner ports to said liner with watertight gaskets;
injecting water through said manifold.
5 . The method of claim 4 wherein transporting each of said curved steel panels with a boom further comprises:
attaching a panel box attachment to said boom;
attaching said panel box attachment to said panel box located at the center of gravity of each of said curved steel panels so that said boom attaches said panel box attachment to a said panel box;
lifting each of said curved steel panels with said boom.
6 . The method of claim 5 wherein said method of attaching said panel box attachment to said panel box comprises orientating said panel box attachment and said boom in a longitudinal direction of one of said curved steel panels.
7 . The method of claim 5 wherein said method of attaching said panel box attachment to said panel box comprises orientating said panel box attachment and said boom in a transverse direction of one said curved steel panels; rotating said one said curved steel panels wherein said one said curved steel panels is positioned so that a longitudinal direction of said one said curved steel panels is vertical.
