A method for using a heated portable vacuum slurry box to efficiently store and transport material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to be meet space restriction requirements at a well site while as well as function within the environmental conditions of winter and summer seasons. The method includes a preferred method to unload the slurry box.

A tailgate assembly includes a tailgate hinge that is operable to attach a tailgate to a vacuum tank such that the tailgate is movable between an open position and a closed position, the vacuum tank operable to withstand vacuum pressure when the tailgate is in the closed position. A tailgate warming tube loop is operable to circulate a heated fluid through the tailgate, the tailgate warming tube loop attached to an interior surface of the tailgate and a first rear pipe flange that includes a first rear pipe flange warming channel in communication with the tailgate warming tube loop.

A liquid storage vessel having a base with a bottom and an interior floor; a continuous side extending vertically from the base and having an interior surface, the bottom and continuous side each including an internal layer and an external layer separated by a material barrier and configured such that the interior layers form an inner containment liner, and the external layers form a continuous exterior structural shell enclosing the inner containment liner. A top is affixed to the continuous side and has an interior ceiling. Access to the tank interior is provided by one or more manways. Mounting and connecting structures enable the tanks to be stacked directly atop one another and then structurally connected. The exterior structural shell is fabricated from high performance fiber reinforced concrete, and the inner containment liner is fabricated from a geopolymer concrete blend.

A container for the transport and storage of goods includes an internal fillable tank and an external support structure surrounding the tank. The external support structure has a base structure arranged below the tank, such that a base of the tank is supported on the base structure. The external support structure also has an upper support structure arranged above the tank for absorbing loads exerted on the tank from above. The base structure includes a plurality of lower column portions, and the upper support structure includes a plurality of corresponding upper column portions, which each project from opposing faces of the base structure and the upper support structure respectively and which meet somewhere along the height of the tank, thereby forming a number of columns for laterally supporting the tank.

A stackable container system is configured to provide stacked receptacles for receiving bulk material therein. The stackable container system includes a first receptacle configured to provide a respective stacked receptacle. The first receptacle includes a receptable bottom, a receptable top, and a receptacle side extending along an upright container axis between the receptacle bottom and top, with the first receptacle presenting a container chamber. The receptacle top is configured to at least partly support another one of the stacked receptacles stacked relative thereto along the upright container axis. The receptacle top and the receptacle side have, respectively, a top peripheral margin and a side peripheral margin that extend laterally about the upright container axis, with at least part of the top peripheral margin being laterally outboard of the side peripheral margin. At least part of the top peripheral margin is interconnected to the side peripheral margin along a transition section that extends laterally between the receptacle top and the receptacle side.

A spill containment system for container tanks which include a liquid container and a steel frame surrounding the liquid container. The overall dimensions of the container tank are approximately twenty feet long, eight feet wide and eight and a half feet high. Beneath one or more stacked container tanks is a containment pan assembly including a liquid-tight pan having an interior capable of holding at least a portion of the contents of one liquid container. The containment pan assembly has an upper rectangular section that supports the container tanks and also has a length of about twenty feet and a width of eight feet. However, the entire height of the containment pan assembly is between eight inches and twenty-four inches. Additional similarly constructed containment pan assemblies are arranged adjacent the first assembly with hoses interconnecting the interiors of the several liquid-tight pans of the several containment pan assemblies.

Certain aspects of the present disclosure provide for modular containers with specialized corner fittings. In one example, a container, includes: six sides; and eight corner fittings, wherein each respective corner fitting of the eight corner fittings comprises: a first outward face on a first side of the six sides; a second outward face on a second side of the six sides; a third outward face on a third side of the six sides; and a corner fitting aperture in at least one of the first outward face, second outward face, or third outward face and centered approximately 3.379 inches from a first edge of the respective corner fitting and approximately 3.379 inches from a second edge of the respective corner fitting.

Certain aspects of the present disclosure provide techniques for a modular container, including: six sides, wherein: each side of the six sides of the modular container comprises at least four surface connector arrangements, each surface connector arrangement of the at least four surface connector arrangements comprises at least two connector elements, wherein: at least one connector element of the at least two connector elements is of a first type, and at least one connector element of the at least two connector elements is of a second type; and an access door in at least one side of the six sides.

A stackable container system is configured to provide stacked receptacles for receiving bulk material therein. The stackable container system includes a first receptacle configured to provide a respective stacked receptacle. The first receptacle includes a receptable bottom, a receptable top, and a receptacle side extending along an upright container axis between the receptacle bottom and top, with the first receptacle presenting a container chamber. The receptacle top is configured to at least partly support another one of the stacked receptacles stacked relative thereto along the upright container axis. The receptacle top and the receptacle side have, respectively, a top peripheral margin and a side peripheral margin that extend laterally about the upright container axis, with at least part of the top peripheral margin being laterally outboard of the side peripheral margin. At least part of the top peripheral margin is interconnected to the side peripheral margin along a transition section that extends laterally between the receptacle top and the receptacle side.

A container includes a receptacle including an upright receptacle side and a receptacle bottom that cooperate to at least partly define a container chamber. The bottom presents a peripheral margin, with the side being attached to the bottom along the peripheral margin and extending upwardly relative to the bottom along an upright container axis. The receptacle further includes a drain configured to permit material flow out of the chamber, with the drain intersecting the bottom to define a drain opening that fluidly communicates with the chamber. The drain opening is spaced inboard from the peripheral margin and is laterally offset from the container axis in an offset direction. The bottom includes first and second floor sections extending inboard from the peripheral margin and joined relative to each other along a first gutter area adjacent the drain opening. The first floor section slopes downwardly toward the first gutter area in the offset direction and the second floor section slopes downwardly toward the first gutter area in a direction opposite the offset direction, with the floor sections configured to cooperatively advance material within the chamber toward the drain opening.
