A flexible tank is used to transport bulk liquids or semi-liquid materials inside of a multi-modal shipping container. It has water proof inner layers and an outer layer, which are formed and welded together to have seams at both ends of the flexible tank. A discharge valve is provided at one end of the flexible tank and an additional piece of material, referred to as a cape, is attached at the other end of the flexible tank. The flexitable tank is situated in the container so that the end with the discharge valve is at the container opening and the end with the attached cape is at the rear of the container. The cape can be used by equipment positionable at the opening of the container to completely discharge the bulk liquids or semi-liquid materials from the flexible tank by pulling and winding up the cape and the layers of the flexible tank from the rear of the container.

A liner discharge structure, and associated liner and container system are disclosed. A liner discharge structure according to the present disclosure can include: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with container liner, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring therein.

A fuel tank for a generator or the like, wherein the fuel tank includes a rigid outer fuel tank structure and an inner bladder. The outer fuel tank structure includes a longitudinal channel for receiving the inner bladder. End caps are disposed on either end of the outer fuel tank structure, so that the internal bladder may be pulled therein with cables or the like. When the internal bladder needs to be replaced due to damage or corrosion, the end caps are removed and cables may be attached to one end of the damaged internal bladder for pulling it from the outer fuel tank structure. Additionally, a replacement bladder may be attached via cables to the other end of the damaged bladder, so that the replacement bladder is pulled into one end of the outer fuel tank structure while the damaged bladder is being pulled out the other end thereof.

A water containment apparatus includes a straight strut arrangement comprising a plurality of straight strut assemblies forming an alternating v-shape and inverted v-shape pattern; and a curved strut arrangement comprising a plurality of corner strut assemblies forming a desired curvature and connecting two straight strut arrangements to form a closed loop water containment system.

A liner discharge structure, and associated liner and container system are disclosed. A liner discharge structure according to the present disclosure can include: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with container liner, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring therein.
