The invention provides a liquefied gas carrier multi-cabin replacement, cabin cooling and filling method and system. The method comprises the following steps: S1, drying and inerting a plurality of liquid tanks based on a series connection mode; s2, replacing a plurality of liquid tanks and cooling the tanks at a liquefied gas shore station; s3, after the liquid tank on the stern side is cooled, filling operation is conducted; s4, after the filling operation of the liquid tank on the stern side is completed, the hose connected with the shore station is removed, and the ship leaves the shore station and goes to a preset offshore area for a sea test; and S5, cabin cooling and filling operation of other liquid cabins is completed. According to the invention, the reliquefaction device is used for treating cargo steam, controlling the pressure in the cabin and cooling the liquid cabin. Replacement is completed in a series connection mode, cabin cooling, filling and equipment testing are completed in a parallel connection mode, the replacement, cooling and cargo lightering time is shortened, the gas test period is shortened, and the gas test is economical and environmentally friendly.

    本申请提供一种液化气船多舱置换、冷舱、加注方法及系统。所述方法包括:S1、基于串联方式对多个液舱进行干燥和惰化;S2、在液化气岸站进行多个所述液舱的置换和冷舱;S3、在船艉侧的液舱完成冷舱后进行加注作业;S4、在船艉侧的液舱完成加注作业后,拆除连接岸站的软管,船舶离开岸站前往预定海上区域进行海试;S5、完成其余液舱的冷舱和加注作业。本申请通过使用再液化装置处理货物蒸气,控制舱内压力,以及冷却液舱。本申请通过采用串联方式完成置换、采用并联方式完成冷舱、加注、设备试验,缩短置换、冷却及货物驳运时间,减少气体试验周期,使气体试验经济、环保。
