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 indispensable in areas where construction of fixed type charging stations for natural gas is difficult.
The vessels can be stored under high pressure of max. 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. In particular, they are in very efficient to take the place of long distance gas pipelines in large countries like The Middle East, China, India, and Russia, and the demand for them is gradually increasing.
