| Abstract: | This paper takes the 6500m3 liquefied gas carrier as the object to study the steady state temperature field of the liquid tank saddle and its surrounding hull structures based on general-purpose finite element analysis software PATRAN/NASTRAN. The 3D finite element model of the ship cabin is established to compute the temperature field of the saddle and its surrounding hull structures under scantling draft; the steel grade and design thickness of this region are then determined based on minimum allowable design temperature. |
