A method for providing inventory for expedited loading and transport of compressed natural gas entails obtaining pressurized high-energy content gas; separating the high-energy gas into saturated gas and liquids; and removing impurities from the saturated gas. Water is removed from the gas forming a dry pressurized gas. The dry gas is cooled forming a two-phase gas. The gas is loaded into a storage element located on a floating vessel, while the liquids are loaded into the storage element forming a mixture. One or more storage elements are collected on the land to create an inventory that is quicker to load than comparable loading of natural gas unto the floating vessel. The floating vessel transports the inventory to a desired location at a lower cost than comparable submarine pipeline transport costs for distances of less than about 2500 nautical miles while utilizing the vapor phase during transit to power the floating vessel.
