The invention relates to the technical field of ships, and discloses an LNG storage tank and a ship. The LNG storage tank comprises a tank body, and the tank body is arranged on a deck of the ship body. The LNG storage tank further comprises a partition plate, a liquid pumping assembly and an inflation assembly. The partition plate is arranged in the cavity of the tank body and divides the cavity into a first cavity and a second cavity in a sealed mode, the first cavity is used for storing LNG, and the partition plate can slide along the cavity so that the volume of the first cavity and the volume of the second cavity can be changed. The liquid extraction assembly comprises a liquid extraction pipe and a liquid extraction pump, one end of the liquid extraction pipe communicates with the interior of the first cavity, and the other end of the liquid extraction pipe is connected to the liquid inlet end of the liquid extraction pump. The inflation assembly comprises an inflation pipe and an inflation pump, one end of the inflation pipe communicates with the interior of the second cavity, and the other end of the inflation pipe is connected to the air outlet end of the inflation pump. The gas pressure in the first cavity is adjusted, evaporation of LNG is reduced, safety is improved, reliquefaction operation on the LNG is avoided, cost is reduced, and the utilization rate of the LNG is also improved.

    本发明涉及船舶技术领域,公开了一种LNG储罐及船舶。LNG储罐包括罐体,罐体置于船体的甲板上。LNG储罐还包括:隔板、抽液组件和充气组件。隔板置于罐体的腔体内部并将腔体密封分隔为第一腔室和第二腔室,第一腔室用于存放LNG,隔板能够沿腔体滑动,以使第一腔室以及第二腔室的容积变化。抽液组件包括抽液管和抽液泵,抽液管的一端连通于第一腔室内部,另一端连接于抽液泵的进液端。充气组件包括充气管和充气泵,充气管的一端连通于第二腔室内部,另一端连接于充气泵的出气端。本发明实现了调整第一腔室内的气压,减少了LNG的蒸发,提高了安全性,避免了对LNG进行再液化操作,降低了成本,也提高了LNG的利用率。
