With the aim of reducing greenhouse gas emissions by 20 percent by 2020 and by 50 percent by 2050 from their 2005 level, International Maritime Organization (IMO) regulated the emissions of SOx and NOx by setting the emission control area in 2012. Since these environmental regulations have been reinforced, demands for the LNG fuel ships are expected to increase dramatically. Accordingly, the worldwide shipbuilding companies spur the development of the LNG fueled ships. Therefore, it is essential to carry out the research on the development of LNG fuel tank, which is one of the important components of the LNG fuel supply system. In this study, the deliberate finite element analysis of type-B LNG fuel tank for 10,000 TEU containership was carried out to evaluate structural safety and provide the process for analyzing stress levels and evaluating fatigue life of target structural. In particular, thermo-structural analysis and fatigue analysis were carried out using the databases on materials and structures of LNG fuel tank.
