Experimental and numerical research was conducted to investigate the effect of liquid filling ratios on the thermal response and safety of a vertical cylindrical liquefied gas storage tank. Low filling ratios were considered to reveal the distribution characters of the medium temperature and wall temperature, as well as the pressure rise histories. The results show that with less liquid filled, the dry wall temperature was higher thus lead to the wet wall to be hotter and more heat transferred into the liquid medium from per unit wall area. As a result, the temperature in the bulk liquid zone rose faster and the stratification degree was larger and last longer. Under the combined influence of the higher pressure and the degradation of the wall material at the higher temperature, the less filled tank can stand for shorter period in thermal environment. Moreover, if the tank failed after the same heating period, the high grade energy retained in the liquid medium under lower filling ratio would more likely bring serious consequence.
