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 m3 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.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
