Liquefied natural gas (LNG) is natural gas that has been cooled to _259 degrees Fahrenheit. It occupies 0.17% of the volume of natural gas, making cost-effective overseas transport by large-capacity ships between LNG processing terminals or ports possible. LNG technologies are associated with key processes of liquefaction, transportation and regasification. These processes include operational technologies linked to process management, and information technologies allied with shipping, logistics and contract/trading.
