NAVIGATION (CONSTRUCTION) REGULATIONS 1968 - REG 9

(1)

A ship shall be provided with a collision bulkhead.

(2)

The collision bulkhead shall be watertight up to the bulkhead deck.

(3)

The distance between the collision bulkhead and the ship's forward perpendicular shall be not less than five per centum of the length of the ship and not more than ten feet plus five per centum of the length of the ship.

(4)

If the ship has a long forward superstructure, the collision bulkhead shall be extended to the deck next above the bulkhead deck.

(5)

Where an extension of the collision bulkhead is required by the last preceding subregulation:

(a)

the extension shall be weathertight; and

(b)

if the extension is not fitted directly over the bulkhead below:

(i)

the distance between the extension and the ship's forward perpendicular shall be not less than five per centum of the length of the ship; and

(ii)

the part of the bulkhead deck which forms the step shall be made weathertight.

(6)

The plating and stiffeners of the extension required by subregulation (4) of this regulation shall be constructed in accordance with the provisions of the Third Schedule as if the extension formed part of a bulkhead immediately below the bulkhead deck.

(7)

Except as provided in the next succeeding subregulation, the collision bulkhead may be pierced below the margin line by not more than one pipe for dealing with fluid in the forepeak tank, if the pipe is fitted with a screwdown valve capable of being operated from above the bulkhead deck and the valve chest is secured inside the forepeak tank to the collision bulkhead.

(8)

Where the forepeak is divided to hold two different kinds of liquids, the Authority may allow the collision bulkhead to be pierced below the margin line by two pipes, each of which is fitted in accordance with the last preceding subregulation, if the Authority is satisfied that there is no practical alternative to the fitting of such a second pipe and that, having regard to the additional subdivision provided in the forepeak, the safety of the ship is maintained.
