Based on the experience of a ship yard designing and building LNG(Liquefied Natural Gas)vessels,this paper re-views the installations of NO96 membrane cargo containment systems on the vessels and the evolution of the design of NO96 system,from NO96 PERLITE,NO96 GW,NO96 L03+to NO96 SUPER+.The principal specifications of different type of NO96 membrane cargo containment system,the BOR(Boil Off Rate),strength and weight and the relationship between them,are studied.With the design development of NO96 membrane cargo containment system,the BOR has been reduced from the initial value 0.150％to the current value 0.085％.Due to the application of new material and rationalized structure design,the strength and weight of the system have been improved significantly,too.
