Compressed Natural Gas (CNG) movable vessels are most useful for transporting large volumes of natural gas to areas where there is no infrastructure of natural gas supply or it is difficult to establish one. And it is independensable in areas where construction of fixed type charging station for natural gas is difficult. The vessels can be stored up to high pressure of 250 bar, and after the vessels are combined into one module by multiple of ultra large vessels, large quantity of gas can be stored and transported.
