초록
Spherical type LNG carrier has many advantages, but has a demerit it is more expensive than membrane type one. Therefore, when calculatingthe initial estimate of spherical type LNG carrier, high accuracy calculation of tank weight has to be carried out. In this study the simplifiedanalysis method which is able to calculate stresses of all the tank zones is established and has special feature to deal with static anddynamic loading. In order to verify the established method, the design results obtained through the method in this study have been comparedwith those of existing ship obtained from finite element analysis. As a result, the usability of simplified analysis method has been confirmed.
