Based on the basic principles of heat conduction analysis, this paper studies the steady state temperature field of a 3800t asphalt carrier loaded with high temperature liquid cargoes using the MSC PATRAN/NASTRAN finite element computation software, and checks the temperature tension of the hull structure based on the numerical results;moreover, the influence of using different insulating layers on the resulting hull structural strength is analyzed.
