A shipping container supporting assembly comprises a base member having a top surface and a width greater than 8 feet and a top surface and at least one connector extending from the top surface positioned and selected to be engagable within a twistlock opening of the intermodal shipping container. The may extend past one of the at least one connectors to form a weight support platform. A kit may include the base member and at least one weight.

A cargo optimizing device includes a rectangular frame having transverse forklift pockets; a rectangular deck housed within the rectangular frame; and stabilization rollers pivotally joined to the rectangular frame at opposing longitudinal ends. The rollers snugly engage with vertical channels of a corrugated shipping container sidewall in an extended position oblique to the rectangular frame and retract to an upright storage position abutting the rectangular frame. The cargo optimizing device forms a second stacking level in a shipping container which otherwise has an upper level of unused space. The device can be supported by legs or suspended by belts.

Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.
