Abstract

Abstract

The construction period of LNG stainless steel storage tank is generally 6 to 8 months. During the construction, the steel surface is affected by solar radiation and the temperature effect will affect the structure. Through the finite element simulation, the non-uniform temperature field distribution of the tank wall under solar radiation was obtained, and it was found that when the latitude increased by every 10°, the maximum temperature increased by 3%. Considering the solar radiation, the maximum stress and maximum radial displacement of the tank wall increased by 96% and 832%, respectively, compared with the working condition considering only the effect of gravity. During the construction of cold insulation layer, a gap of 30 mm should be reserved to ensure the structural integrity.
