LNG cargo containment systems
LNG has three major characteristics as a seaborne trade cargo: the super low temperature (-160°C), a low specific gravity (0.43 to 0.50) and flammability. Up to now, various cargo containment systems designed to handle these characteristics have been put into practical use. The main competing systems are French membrane technology, and Japanese and Norwegian self-supporting tanks (Moss Rossenberg system), structurally independent of the ship structure.
