A compression system is disposed in a container and shipped to a location having a supply of natural gas. The compression system connects to the natural gas supply, compresses gas from the supply, and provides compressed gas to a consumer. The container, which can be a standardized ISO shipping container, is fitted with removable vents at designated locations. Strategic positioning of compression system components in combination with the removable vents allows for ready access to the compression system for repair and maintenance.

A method of generating a supply of compressed natural gas using an International Standards Organization (ISO) shipping container having an interior, a roof and a length greater than a width, the method comprising: a. installing a natural gas compressor package in the interior of the ISO shipping container to define a modular compressed natural gas unit;b. mounting a plurality of storage tanks on the roof in a first portion of the roof;c. providing a louvered vent in an opening of a second portion of the roof directly adjacent the storage tanks and positioned such that the tanks do not substantially overlap the louvered vent, the louvered vent comprising selectively movable louvers to open and close the vent, and moving the louvers in a direction to open the vent when the compressor package is operating, and moving the louvers in an opposite direction to close the vent when the compressor package is at rest;d. directing a supply of natural gas to the compressor package; ande. compressing the natural gas in the compressor package to generate compressed gas and delivering the compressed natural gas to the storage tanks on the roof for subsequent dispensing to vehicles. 11. The method of claim 10, further comprising providing a dryer in the ISO shipping container, attaching an end of a regeneration line to the dryer and locating another end of the regeneration line outside of the ISO shipping container, flowing the natural gas through the dryer, removing the dryer from communication with the natural gas, and removing moisture from the dryer by flowing a regeneration gas through the dryer. 12. The method of claim 10, further comprising providing a control unit in the ISO shipping container, wherein the control unit comprises a touch screen for communication with the compressor package and for manually controlling the compressor package and a controller for automated control of the compressor package. 13. The method of claim 10, wherein: mounting a plurality of storage tanks on the roof comprises providing each of the storage tanks with a cylindrical portion having a longitudinal axis:mounting two spaced apart supports on the roof, each extending across the roof of the container perpendicular to the length of the container, each of the supports having a plurality of semi-cylindrical upward facing recesses;placing each of the storage tanks in one of the recesses of both of the supports with the axes parallel with each other and parallel with the length of the container; andstrapping the storage tanks to the supports. 14. The method of claim 10, wherein the modular compressed natural gas unit is mounted on top of a structure that houses a business. 15.
