A hydrocarbon fluid storage structure has a storage vessel containing hydrocarbon fluids therein and a containment vessel fully surrounding the storage vessel so as to provide secondary containment to the storage vessel. A heater is surrounded by heat exchanger fluid within a heat exchanger vessel within the storage vessel. The exterior of the containment vessel is insulated. The heat exchanger fluid is passively circulated within a closed loop path defined by the heat exchanger vessel. Connecting valves providing external access to the contents of the storage vessel are received within a valve housing in heat exchanging relation with a containment space between the containment vessel and the storage vessel.

An insulated tank for storing flammable and combustible liquid comprises an outer containment tank and an inner storage tank that defines a reservoir for storing flammable and combustible liquid. The inner storage tank is received within the outer containment tank such that a space is defined between the walls of the inner storage tank and the walls of the outer containment tank. The space contains one or more perlite boards to insulate the inner tank.

A containment tray for holding, transporting and/or storage of objects, such as, preferably, liquid-filled or, more preferably, oil-filled objects. More particularly, the invention relates to a containment tray capable of holding, transporting and/or storing liquid-filled industrial objects and preventing leaking of both hazardous and non-hazardous materials from such objects when in the containment tray into the outside environment.

Disclosed is a containment system for a substance in liquid or particulate form including juxtaposed collection containers and at least one connection bracket including a flattened base and locking unit including at least two locking elements, protruding from two respective ends of the base, wherein the collection container includes a support base which has at least one groove on its outer face which opens onto at least one edge of the support base, the groove having at least one indented housing having a plan shape equal to that of the locking elements and wherein the bracket has the first locking element inserted into the housing of a first container and the second locking element inserted into the housing of a second container.

A bladder for retaining material to be stored within a bladder tank. The bladder comprises a flexible enclosure comprising a floor portion connected to one or more wall portions, and a leak retention enclosure having upper and lower edges sealed to the flexible enclosure to create a sealed chamber between the flexible enclosure and the leak retention enclosure. Leakage of material from within the flexible enclosure adjacent to the sealed chamber is received within the sealed chamber and retained by the leak retention enclosure.

An apparatus includes a floor having an impermeable material, where the floor has multiple edge portions and each edge portion corresponds to an edge of the floor. The apparatus also includes multiple wall sections configured to form multiple free-standing walls around a perimeter of the floor, where each wall corresponds to one of the edge portions. The apparatus further includes multiple brackets, where each bracket is configured to fit over an associated one of the walls after the corresponding edge portion of the floor is draped over the associated wall. Each bracket is configured to fit against sides of the associated wall so as to hold the corresponding edge portion in place. Each bracket includes (i) first and second plates disposed on opposite sides of the associated wall and (ii) one or more bars extending over a top surface of the associated wall and connecting the first and second plates.
