In this paper a Modified Three-District Model was introduced to study the marine medium-sized horizontal LNG storage tank. The horizontal cryogenic tank evaporation rate and the lossless storage time with the liquid nitrogen were experimented. The maximum error of the pressure change and the lossless storage time obtained by the modified Three-District Model and by the experiment was observed to be only about 4.7%. So the applicability and reliability of the modified model for marine medium-sized horizontal LNG storage tank have been verified. Furthermore, based on the marine horizontal LNG storage tank with an effective volume of 250 m in a dual fuel-filled barge, the forecast analysis on the pressure change under different conditions of fullness rate, environmental temperature and heat leakage has also been discussed.
