Some of these vessels are designed to carry LNG. Others carry LPG.
- LNG is Liquefied Natural Gas. (The gas that comes from gas reserves below the surface of the earth).
- LPG = Liquefied Petroleum Gas (The gas that is a by-product of the oil refining process.)
LNG is liquefied by cooling it to -165˚C. This makes it easier to handle and, as gas when liquefied occupies less space, far greater volumes can be carried by the gas carriers.
Special shoreside terminals are constructed to load and discharge these cargoes.
