The invention provides a liquefied gas ship and a cargo hold safety valve ventilation system thereof, wherein a ventilation pipeline is horizontally laid on an exposed deck of a liquid cargo area of the ship, one end of the ventilation pipeline is connected to a dome of a liquid cargo hold and communicates with the interior of the liquid cargo hold, and the other end of the ventilation pipeline isconnected to a ventilation mast; the ventilation mast is installed on a settlement deck of a ship, and the sum of the height of the ventilation mast and the height of a ship body structure at the installation position is smaller than the design height of a bridge. The settlement deck is used for arranging the ventilation masts, the clearance height of a ship can be reduced, the bridge trafficability of the ship is enhanced, the cabin capacity of a cargo cabin does not need to be reduced, the optimal cabin type design can be achieved, the supply efficiency of the ship to a shore station is improved, the ship operation cost is reduced, and the applicability of the ship is further improved.
本发明公开了一种液化气体船舶及其货舱安全阀透气系统,所述船舶的液货区域的露天甲板上水平敷设有透气管路,所述透气管路的一端连接至液货舱的穹顶并与液货舱的舱内相连通,透气管路的另一端连接至透气桅,所述透气桅安装在船舶的沉降甲板上,透气桅的高度与其安装位置处的船体结构的高度之和小于桥梁的设计高度。本发明利用沉降甲板来布置透气桅,可以降低船舶的净空高度,增强船舶的桥梁通过性,不需减小货舱的舱容,可以实现最优化的舱型设计,提高船舶对岸站的补给效率,降低船舶营运成本,进一步提高了船舶的适用性。
