The invention provides a gas ship multi-cabin replacement system and method. The system comprises a tank car, a filling pipe, a condensation pipe, an auxiliary filling pipe, an exhaust pipe and a flare tower. The tank car is used for loading liquefied gas; the filling pipe is connected with the tank car and the fourth liquid cargo tank, the condensation pipe is used for connecting the fourth liquid cargo tank and the tank car, the condensation pipe and the filling pipe are connected in parallel, and the auxiliary filling pipe is connected between the filling pipe and the condensation pipe; and the exhaust pipe is connected between two adjacent liquid cargo tanks. The multiple liquid cargo tanks are connected in series through the exhaust pipes, the cargo steam generated in the front tank replacement, cold tank and filling process is fully utilized for replacement of the rear tank, replacement of other tanks is completed while the cold tank and liquid cargo filling are completed, extra cargos do not need to be consumed, and efficient utilization of the cargo steam is achieved; the replacement of a plurality of cabins can be completed by connecting the tank car with one liquid cargo tank, so that the use amount of gas cargos is saved, and the conditions of environmental pollution and the like caused by outward discharge of cargo steam are avoided.

    本申请提供一种气体船多舱置换系统及方法。所述系统包括槽车、加注管、冷凝管、辅助加注管、排气管、火炬塔。槽车用于装载液化气体;加注管连接槽车与第四液货舱,冷凝管用于将第四液货舱与槽车进行连接,且冷凝管与加注管并联连接,辅助加注管连接于加注管和冷凝管之间;排气管连接于相邻两个液货舱之间。本申请通过排气管将多个液货舱进行串联连接,充分利用前舱置换、冷舱、加注过程中产生的货物蒸气来进行后舱的置换,使得冷舱及加注液态货物的同时完成其余舱的置换,而不需要消耗额外的货物,实现货物蒸气高效利用;通过将槽车与一个液货舱连接即可完成多个舱室的置换,节省气体货物的使用量,避免货物蒸气外排造成环境污染等情况。
