Bridgestone Liquefied Gas Co., Ltd., developed a new method for constructing membrane-type cargo tanks for LNG tankers in which the inner membrane vessel is designed so as to subject the vessel to the most favorable stresses at low-temperature loaded conditions without complicated corrugations or convex and concave portions. The LNG tank construction consists of an outer rigid vessel, a heat-insulating layer, and an inner vessel with at least 1 seam (formed by connecting the 2 sides so that the edges overlap by an amount corresponding to the contraction of the inner vessel at low temperature). The inner vessel is constructed before the heat-insulating layer, improving welding reliability and facilitating inspection. Selection of the heat-insulating material for the insulating layer depends on the particular areas used: Pearlite concrete, for example, can be used for forming the side-wall portions. Also recommended are foam sulfur or foam concrete that contains foam sulfur or foam glass as a reinforcement.
