Division .3.2 F1

Except as provided in paragraph .3.3, the collision bulkhead may be pierced below the margin line by no more than one pipe for dealing with fluid in the fore peak tank, provided that the pipe is fitted with a screw-down valve capable of being operated from above the bulkhead deck, the valve chest being secured inside the fore peak to the collision bulkhead. However the fitting of this valve on the after side of the collision bulkhead may be accepted provided that the valve is readily accessible under all service conditions and the space in which it is located is not a cargo space.
