The invention relates to an inexpensive technique and procedure to add storage capacity to existing hydrocarbon storage tanks that have a double seal floating roof. The additional storage capacity is obtained by installing an extension that is strong enough to provide the upper seal of the double seal arrangement to maintain a sealed vapor space that allows the roof to move higher within the existing peripheral wall of the storage tank.

A modular portable storage container system includes a storage container having first and second sections. The first section defines a first partial volume of storage space and the second section defines a second partial volume of storage space. The system further includes a lock mechanism with a lock arm, lock handle, and pivot shaft defining an axis of rotation. The lock arm and handle are fixed for common rotation with the pivot shaft. The arm extends radially outward from the pivot shaft to a roller assembly. A lock track is disposed within the second section and extends from a fluted open portion to a closed end, with a continuous track portion disposed therebetween. The first and second sections are movable between at least closed and open positions. In the closed position, the roller assembly engages with the lock track and retains the first section in contact with the second portion.

A movable equipment loading and unloading structure for movably mounting equipment within a container includes a loading and unloading assembly and a guide assembly. The loading and unloading assembly includes a loading and unloading rail mounted to a ceiling of the container and a loading and unloading wheel assembly movably coupled to the loading and unloading rail. The loading and unloading wheel assembly is mounted to a side of the equipment. The guide assembly includes a guide rail mounted to a floor of the container and at least one guide wheel rollably coupled to the guide rail. The guide wheel is mounted to another side of the equipment opposite to the side mounted to the loading and unloading wheel assembly.

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

Container adapted for cargo or personnel transport, the container being substantially prismatic, cylindrical or cubic in shape, wherein the container comprises: an internal surface and an external surface, a rigid frame, which defines a plurality of container faces, wherein the confluence of two or more of said container faces define edge portions being substantially chamfered, and one or more shock absorbing corner protectors adapted for being mounted on the edge portions, characterized in that the edge portions of the rigid frame comprise one or more beams arranged substantially in parallel to the direction of the confluence of two container faces, and the inner face of the corner protectors comprise at least a flange adapted for fitting in the one or more beams of the edge portions, such that the corner protectors substantially protrude from the external surface.

A modular storage tank has a secondary containment receptacle defined by a plurality of rigid floor panels which are joined to one another to form a continuous floor and a plurality of rigid, upright wall panels joined to one another to form a continuous perimeter wall extending upwardly from the continuous floor, and a primary containment receptacle defined by a flexible line membrane within the secondary containment receptacle. The wall panels are joined to one another using a gasket and threaded fasteners such that the wall panels are readily separable from one another for reuse at different site after disassembly. The floor panels are joined to one another and to the perimeter wall by welded seams.

A foldable water tank comprises a foldable receptacle including an open receptacle portion and a closed receptacle portion, the open receptacle portion communicating with the closed receptacle portion such that water from the open receptacle flows to the closed receptacle, the open receptacle portion including side walls; a folding frame operably associated with the side walls to support the sidewalls in an upright position; and the closed receptacle portion extending outwardly from the frame.

A hollow container or box formed from a roof, a first side (i.e., or first upper and lower sides), a second side (i.e., for second upper and lower sides), a rear side (i.e., or rear upper and lower sides), a door (i.e., or upper and lower door), and a base placing the container or box in a fully assembled position. Unique side and end access doors are provided. Each of the sides are releasably coupled or hingedly connected to one another and the adjacent sides are hingedly coupled to the base. Upon releasing the sides from one another and rotating each relative to one another in a particular order along various axis rotation, the container or box is transitioned from a fully assembled position into a flat, parallel orientation, fully collapsed position.

A roll-off container, a system consisting of at least two roll-off containers, an equipment trolley system and the use of a roll-off container are described. The roll-off container comprises a main frame arranged on a platform. The platform comprises attachment rollers on its bottom side and an upward-pointing hook with a transverse strut on a face side. The main frame comprises a bottom, side walls, and roof sections. On an upper end of the main frame on both longitudinal sides, a roof structure is rotatably mounted, wherein the roof structure comprises at least first and second roof-frame sections, each having a width equal to a height of the side walls of the main frame, and a length of which corresponds to a length of the main frame.

A modular logistics system (10) including: a container (12) having a top (14), a base (16), side walls (18) and end walls (20); and a storage frame (23) housed within the container (12) in an operationally ready state, wherein in a first configuration the side walls (18) and end walls (20) are fixed to form an enclosure around the storage frame (23) for transport of the storage system (10), and in a second configuration the end panels (20) are removable to allow extension of the storage frame (23), and at least a portion of one of the side walls (18) is removable to provide access to the storage frame (23) during use, so that the container (12) and the storage frame (23) are transported and installed as a single unit.
