Pt.4 Ch.6 Sec.3 A402
“For cargo vessel pipes passing through the collision bulkhead below the deepest load line are to be provided with a shutoff valve fitted directly on the collision bulkhead operable from above the freeboard deck”
Pt.4 Ch.6 Sec.3 A403
"For valves fitted on the after side of the collision bulkhead, local operation will be acceptable provided that the valves are readily accessible under all service conditions and provided the space is not a cargo space."
以上是DNG规范中关于该截至阀的布置有求。可以看出:
1。不是在甲板上设置能够启闭的截止阀,而是直接安装在防撞舱壁上,从干舷甲板上可以操作。
2。如果防撞舱壁之后的区域不是货物处所,而且容易进入,则可以将该阀直接安装在防撞舱壁之后,就地操作。
SOLAS或者各个船级社关于此布置的要求都是如此
