How is LNG transported?
LNG is transported in double-hull ships specifically designed to handle the low temperature of LNG. 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 carriers. LNG carriers are up to 1,000 feet long, and require a minimum water depth of 40 feet when fully loaded. There are currently 136 ships that transport more than 120 million metric tons of LNG every year.

LNG is transported in large ships specially designed to store LNG safely at temperatures near minus 260° F. These ships are double hulled and are about 900 feet long and 140 feet wide. LNG ships are required to meet international maritime construction and operating standards as well as rigorous Coast Guard safety and security regulations.
