是raised quarter deck 的前端壁就不许开门
poop deck的前端壁?
后者需考虑是否符合封闭上层建筑,不是就得600,是的话就是380
如果您讨论的是FREEboard deck 上一层甲板上的门槛高度请参照
(2). Openings in freeboard decks other than hatchways, machinery space openings, manholes and flush scuttles shall be protected by an enclosed superstructure, or by a deckhouse or companionway of equivalent strength and weathertightness. Similarly, any such opening in an exposed superstructure deck, in the top of a deckhouse on the freeboard deck which gives access to a space below the freeboard deck or a space within an enclosed superstructure shall be protected by an efficient deckhouse or companionway. Doorways in such companionways or deckhouses that lead or give access to stairways leading below, shall be fitted with doors in accordance with regulation 12(1). Alternatively, if stairways within a deckhouse are enclosed within properly constructed companionways fitted with doors complying with regulation 12(1), the external door need not be weathertight.
(4). In position 1 the height above the deck of sills to the doorways in companionways shall be at least 600 mm. In position 2 it shall be at least 380 mm.
但是无论如何我理解不了您说的水密门啊
设置水密门的条件是看浸水最终阶段的平衡水线是否位于所考虑的门的门槛之上啊!!!!!!
说的不对的地方,请多指教,另外请问HUGH777如果真需要设置成水密门得话
水密门按照航行时候是否使用分:A保持关闭,B通常关闭,C海上打开
我认为对A类要求门槛高度毫无意义
对B类和C类是否可以参照ICLL对风雨密门得定义呢?
谢谢! |
