Abstract: A method of loading a flexible enclosure, and the flexible enclosure. The enclosure has a floor, a sealable port, and a top enclosure. The top enclosure has an opening that is sealingly closable with an airtight closure. The method includes the steps of selecting a parking location for the enclosure, and positioning the enclosure over the parking location. Equipment, such as a vehicle is loaded in the enclosure. The enclosure is sealed, and the internal atmosphere of the enclosure is modified, such as lowering the oxygen content of the interior atmosphere.

Abstract: A system and method for reducing the oxygen content in a storage/transportation device. The system includes a flexible bag type enclosure, a source if inert gas, and a source of vacuum. The enclosure has sealable input and output ports. The system has a vent to the atmosphere. In use, the interior enclosure environment is suctioned down, and re-pressurized with an inert gas. Sever suction/infusion cycles may be necessary, with possible recirculation taking place between or during cycles.

Abstract: An apparatus comprising an inert gas generator having an outlet and an inlet, and a secure enclosure having an outlet and an inlet. The outlet of the secure enclosure is connected to the inlet of the inert gas generator and the secure enclosure supplies inert gas enriched air having a first oxygen content percentage from the outlet of the secure enclosure to the inlet of the inert gas generator. The inert gas generator is configured to operate on the inert gas enriched air having a first oxygen content percentage to form inert gas enriched air having a second oxygen content percentage, wherein the second oxygen content percentage is substantially lower than the first oxygen content percentage. The inert gas generator may be a membrane inert gas generator. The inert gas generator may be a pressure swing adsorption inert gas generator. The inert gas may be nitrogen.
