In accordance with presently disclosed embodiments, 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.

In accordance with embodiments of the present disclosure, systems and methods for reconfiguring a vertical storage silo used to store proppant (or other dry material) so that the storage silo may be used in a desired orientation at a worksite are provided. The disclosed embodiments may include a vertical storage silo assembly used to selectively deliver material from one of two different outlet orientations. The silo assembly may offer two distinct orientations for an outlet chute relative to a transportation chassis used to transport and erect the vertical silo. The silo assembly may include a storage silo and a base for supporting the storage silo in a vertical orientation, the storage silo being removably coupled to the base. The storage silo may also be rotatable relative to the base to transition or reposition the outlet chute between a right-hand orientation and a left-hand orientation relative to the base.

An unloader for a shipping container includes a supporter having a frame structure and a pallet base supported by the frame structure and configured to receive the pallet and support the shipping container in an elevated position. A gate moving mechanism is supported by the pallet base and configured to engage the moveable gate assembly when the full shipping container is positioned onto the pallet base. A material director has a first end located beneath the pallet base subjacent of the gate moving mechanism. The material director extends downwardly from the pallet base and terminates at a second end opposite the first end. Bulk material is dispensed from the shipping container into the first end and is discharged from the second end of the material director. Shipping containers may be positioned onto and removed from the pallet base without disassembly of the unloader.

A container for holding product therein during shipment and being returned for reuse has at least one track supported by each side of the container. The container has dunnage supports extending between corresponding tracks at the same level. At least one lockable crossbar assembly has one or more locking assemblies to fix the position of the lockable crossbar assembly relative to the tracks. Dunnage may hang from the dunnage supports for supporting products during storage or shipment.

The invention relates to a storage facility for the storage of highly volatile hydrocarbons, comprising at least one vertical round tank (I) which is equipped with a floating cover (5), covering the liquid surface, in the form of a floating roof or a floating ceiling, wherein an annular space (8) formed between the cover (5) and tank wall (3) is sealed by means of flexible sealing elements (9) and wherein fittings (12, 13) for automatic control of overpressures and under pressures in the space (4) under the cover (5) are integrated into the cover (5). The fittings (12, 13) of the at least one round tank (I) are connected to a vapour line (14), the upper end of which is led out of the tank (1) and is in turn connected to a separate vapour expansion tank (15), wherein the round tank (I) and the vapour compensation tank (15) form a closed system.

Described is a containment device for holding a container that defines a container interior volume. The containment device can include a base portion enclosing a base portion interior volume, the base portion including: a plurality of base walls, a trough extending from at least one of the base walls, and a substantially horizontal support surface adapted to support the container above the base portion interior volume. The base portion interior volume can be equal to or greater than the container interior volume. An enclosure can extend above the base portion, the enclosure including a plurality of enclosure walls adapted to surround the container. The enclosure walls can define an opening above the trough, the opening adapted for insertion of the container into the enclosure.

An aircraft water tank is provided. With an aircraft water tank being suspended by a fuselage via bushes, a load applied to each of the bushes is transferred from the bush and an attachment hole to a metal plate. The load transferred to metal plate is transferred to a total of four prepreg projection portions at a section of a thick wall portion of the metal plate and transferred to a total of eight prepreg projection portions at a section of a thin wall portion.
