更正!
仔细看了一下规范,应该不可以。
见DNV规范
“The collision bulkhead may, however, be pierced by necessary
pipes to deal with fluids in the forepeak tank, provided the
pipes are fitted with valves capable of being operated from
above the freeboard deck. The valves are generally to be fitted
on the collision bulkhead inside the forepeak. The valves may
be fitted on the after side of the bulkhead provided that the
valves are readily accessible under all service conditions and
the space in which they are located is not a cargo space. ”
看来只有去首尖舱的压载管才可以在干舷甲板下穿过。
其他的管子可以在干舷甲板以上贯穿,按一般水密处理。多心管可以用MCT or ROX通舱件。
