A proppant storage vessel has a container having a first end wall, a second end wall, a first side wall, a second side wall, a top wall and a bottom wall. The first and second end walls extend between opposite ends of the first and second side walls. The walls define an interior volume of the container. The walls have a rigidity suitable for retaining no less than 30,000 pounds of proppant therein. A top hatch is formed centrally on the top wall and is movable between an open position and a closed position. A bottom hatch is formed generally centrally on the bottom wall of the container and is movable between an open position and a closed position.

1. A modular container system structurally strengthened to transport and store large volumes of proppant effectively therein to supply to a fracturing site, the system comprising: a first container comprising:a first top,a first bottom having a first outlet formed therein to allow large volumes of proppant to flow therefrom when the outlet is in an open position,a first plurality of sidewalls coupled to the first top and first bottom, so as to define a first interior volume of the first container thereby to store the proppant therein, the proppant having a substantially spherical shape and a tightly graded particle distribution,a first plurality of ramps downwardly inclined and extending inwardly from the first plurality of sidewalls to direct the proppant toward the first outlet when the proppant is stored therein, anda first hatch movable toward a second container to transition the first hatch to the open position to allow proppant to flow from the first outlet;the second container adapted to be positioned below the first container, the second container comprising:a second top having an opening formed therein,a second bottom having a second outlet formed therein to allow large volumes of proppant to flow therefrom when in an open position,a second plurality of sidewalls coupled to the second top and second bottom, so as to define a second interior volume of the second container thereby to store the proppant therein, the proppant having a substantially spherical shape and a tightly graded particle distribution,a second plurality of ramps downwardly inclined and extending inwardly from the second plurality of sidewalls to direct the proppant toward the second outlet when the proppant is stored therein, anda second hatch movable toward the first container to transition the second hatch to an open position, and a distance between the first and second containers is great enough to allow the first hatch and the second hatch to be in respective open positions at the same time. 2. The system of claim 1, further comprising a conveyor positioned below the second outlet such that proppant exiting the second container through the second outlet is deposited on the conveyor and transported away from the second container. 3. The system of claim 1, wherein one or more of the first and second containers includes a first plurality of structural supports comprising a first plurality of support braces, the first plurality of support braces including a first set of support braces attached to a first pair of sidewalls and a second set of support braces attached to a second pair of sidewalls, the first set of support braces extending in a plane direction transverse to the second set of support braces. 4. The system of claim 1, wherein the first container further comprises a plurality of support members attached to respective bottom surfaces of the first plurality of ramps, the plurality of support members extending downwardly toward the bottom to support the ramps, and the plurality of support members extend in a substantially horizontal position. 5. The system of claim 1, wherein each of the first and second containers includes a container frame structurally arranged to support another container when filled with large volumes of proppant and positioned in a vertically stacked arrangement thereabove such that each of the first and second containers is structurally adapted to support the other container when the proppant is positioned therein. 6. A modular container system structurally strengthened to transport and store large volumes of proppant effectively therein to supply to a fracturing site, the system comprising: a first container comprising:a first top,a first bottom having a first outlet formed therein to allow large volumes of proppant to flow therefrom when the outlet is in an open position,a first plurality of sidewalls coupled to the first top and first bottom, so as to define a first interior volume of the first container thereby to store the proppant therein, the proppant having a substantially spherical shape and a tightly graded particle distribution,a first plurality of ramps downwardly inclined and extending inwardly from the first plurality of sidewalls to direct the proppant toward the first outlet when the proppant is stored therein, anda first hatch movable toward a second container to transition the first hatch to the open position to allow proppant to flow from the first outlet;the second container adapted to be positioned below the first container, the second container comprising:a second top having an opening formed therein,a second bottom having a second outlet formed therein to allow large volumes of proppant to flow therefrom when in an open position,a second plurality of sidewalls coupled to the second top and second bottom, so as to define a second interior volume of the second container thereby to store the proppant therein, the proppant having a substantially spherical shape and a tightly graded particle distribution,a second plurality of ramps downwardly inclined and extending inwardly from the second plurality of sidewalls to direct the proppant toward the second outlet when the proppant is stored therein, anda second hatch movable toward the first container to transition the second hatch to an open position, each of the first and second containers includes a container frame structurally arranged to support another container when filled with large volumes of proppant and positioned in a vertically stacked arrangement thereabove such that each of the first and second containers is structurally adapted to support the other container when the proppant is positioned therein. 7. The modular container system of claim 6, further comprising a conveyor positioned below the second outlet such that proppant exiting the second container through the second outlet is deposited on the conveyor and transported away from the second container. 8. The modular container system of claim 6, wherein one or more of the first and second containers includes a first plurality of structural supports comprising a first plurality of support braces, the first plurality of support braces including a first set of support braces attached to a first pair of sidewalls and a second set of support braces attached to a second pair of sidewalls, the first set of support braces extending in a plane direction transverse to the second set of support braces. 9. The modular container system of claim 6, wherein the first container further comprises a plurality of support members attached to respective bottom surfaces of the first plurality of ramps, the plurality of support members extending downwardly toward the bottom to support the ramps, and the plurality of support members extend in a substantially horizontal position.
