A large part of the world's LNG (Liquafied Natural Gas) supply comes from countries with large natural gas reserves. These countries include Algeria, Australia, Brunei, Indonesia, Libya, Malaysia, Nigeria, Oman, Qatar, and Trinidad and Tobago.

There are more than 40 gas receiving terminals located worldwide. Japan, South Korea, the United State and a number of European Counties are importors of  LNG.  

LNG is normally transported in double-hulled ships specifically designed to handle the low temperature. These carriers are insulated to limit the amount of LNG that boils off or evaporates. This boil off gas is sometimes used to supplement fuel for the the carriers. LNG carriers are up to 1000 feet long, and require a minimum water depth of 40 feet when fully loaded. There are currently 136 ships which transport more than 120 million metric tons of LNG every year. (Source: University of Houston IELE, Introduction to LNG.)
