A barrel is capable of vacuum loading and unloading, gravity unloading and loading, and pneumatic unloading. A roll-off skid is coupled to the barrel.

A quasi-cylindrical cargo container is formed of a plurality of rigid, curved panels together forming first and second semi-cylindrical shells, and a plurality of rigid, flat extension panels bridging the first and second semi-cylindrical shells. A method of manufacturing the container includes forming the first and second semi-cylindrical shell from the curved panels, forming the quasi-cylindrical shell from the first and second semi-cylindrical shells and the flat extension panels, forming collars conformably encompassing the quasi-cylindrical shell, constricting the collars to compress joints formed at abutting edges of pairs of adjacent panels, rolling the shell and collars sequentially to bring the joints to a lower position, welding inside seams of the joints when at the lower position, removing the collars, rolling the shell sequentially to bring the joints to an upper position, and welding outside seams of the joints when at the upper position.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A collapsible storage silo having an expanded configuration includes: (a) a shell for circumscribing storage space and comprising a plurality of concentrically nested tubular members that are collapsible; (b) a lift system operable to slidably expand the plurality of concentrically nested tubular members to place the silo in its expanded configuration; and (c) a mast operable to support the lift system. The mast is pivotable between horizontal and vertical positions relative to a frame. A winch attaches to the mast and a cable extends between the winch and an outermost tubular member to expand the silo such that inwardly and outwardly projecting lips of nested members engage each other and a conical hopper engages an innermost tubular member. A flexible inner liner attaches between an outermost tubular member and the hopper. A collapsible roof has a flexible roof membrane and a plurality of radially extending foldable rib members.

A transport container (vehicle) used to transport, lift, and transfer approved IBCs containing dangerous goods (including liquids) in Open Seas environments. The transport container meets all criteria specified by DNV-GL for certification of offshore containers intended for transport of approved IBCs for dangerous goods in Open Seas and has been certified by DNV-GL as such. It also provides a (solid) full enclosure of the IBC which provides protection an all sides, top and bottom. An offset hinge, rolling, or retractable, top lid provides a top opening for vertical loading of the IBC, while also providing complete protection of the top, when closed. A hinged door panel provides for front protection while allowing for lateral loading of the IBC. The transport container also incorporates guidance features to ensure the IBC is properly positioned inside the container when loading, and a catch well to contain drips or accidental spillage.

A low profile holding tank-evacuable to a pressure differential of at least about 10 of mercury that includes a plurality of support structures, a peripheral wall, an upper outer layer of mild steel and a lower outer layer of mild steel, each of the upper outer layer and the lower outer layer is configured to be up to about inches thick. At least some of the plurality of support structures are required to be fixedly connected to upper and lower outer layers to prevent damages incurred on the low profile holding tank by repeated applications of the pressure differential of at least about 10 of mercury. At least some of the connections are required to be made from the outside of the tank via a welding, e.g., plug welding, technique.

What is disclosed is an assembly system to create customizable, mobile, lightweight containers and container-like products ranging in size from consumer and commercial storage products to shipping containers and small mobile buildings. The system uses slidable interconnection of various profile shapes of elongated panel modules with same length standardized linear and corner panel connectors, to create container sleeves retained by customizable end framing to become container shells. The container shells are customized to size needed by the number of interconnected panel modules used and the length to which they are cut. Assembly of their few basic parts is simple with a limited range of tools and skills needed. The system further provides for simple, seamless, solid and reversible structural attachment of third party components, without welding or riveting, to achieve specific customization goals as needed. Finally, the system provides for easy and scar free disassembly for shipping, storage reconfiguration, or recycling.
