The idea of the independent prismatic Type B tank system was crystallized in 1970's and a group of the concerns in Japan developed its design standard. With the design standard thus developed, number of LPG carriers and Ethylene carriers of this system were built with the NK class in the beginning of 1980's, and nothing has been reported of serious deficiencies and troubles. Nevertheless, on the occasion of adopting this system for large LNG carrier, the authors attempted to review the design standards to verify their reliability based on the actual experiences of designs, inspections, operations etc. of the ships. We conclude that the prevailing design standard for the system is quite reasonable and this independent prismatic type B tank system is one of the LNG tank systems with high reliability.
