Large gas carriers first put out to sea with the Self-Supporting Prismatic-Type Tank LNG carrier about 30 years ago. This type is strong and reliable and has been used by almost all large LPG carriers, but has not been developed for LNG for various, nontechnical reasons. Having full confidence that this tank system will make for the most efficient LNG carrier design, Ishikawajima- Harima Heavy Industries, Japan, developed the SPB (Self-Supporting Prismatic Type IMO Type B) LNG carrier using advanced technology. It was subsequently approved by the U.S. Coast Guard as well as by the world's major classification societies. This presentation offers the conceptual basis and general features of the ship, including gas consumption trial results and some operational reports from the initial cargo voyages. The study shows that the LNG carrier technology of self-supporting prismatic-type tanks is safe, efficient, and easy to use.
