A Liquefied Natural Gas Carrier (LNGC) is a specialised tank ship used to transport Liquefied Natural Gas (LNG) that is fitted with independent cargo tanks or with membrane tanks at its boiling point of -162 °C, by which independent tanks are completely self-supporting and they do not contribute to the hull strength of a tanker (three different types of independent tanks for gas carriers (IGC Code): Type 'A' (fully refrigerated condition), 'B' (LNG tankers), and 'C' (fully pressurised)). A Membrane Containment system is based on a very thin primary barrier (membrane - 0.7 to 1.5 mm thick) which is supported through the insulation. (e.g., GTT NO96 Membrane system, GTT Mark III & V system, etc.) A Semi-Membrane concept is a variation of the membrane tank system. LNGCs are to prevent leaks and keep the LNG at the cold temperature to keep the liquid form in the 200,000 M3 capacity range.
