Liquefied natural gas carrier

A liquefied natural gas carrier is a gas carrier that transports LNG, natural gas cooled to minus 162 degrees Celsius and reduced to about 1/600th of its gaseous volume. Cargo sits in insulated tanks of membrane type (GTT Mark III or NO96) or self-supporting Moss spherical type, with continuous boil-off gas used as fuel or reliquefied. Standard sizes run around 145,000 to 180,000 cubic meters, with Q-Flex and Q-Max units above 200,000 cubic meters. The IGC Code under SOLAS Chapter VII governs construction. LNG rates trade on the Baltic LNG (BLNG) routes.
