C32 SAFETY OF LIFE AT SEA 



Regulation 8 



Ballasting 



When ballasting with water is necessary, the water ballast should not in 

 general be carried in tanks intended for oil fuel. In ships in which it is not 

 practicable to avoid putting water in oil fuel tanks, oily-water separator 

 equipment to the satisfaction of the Administration shall be fitted, or other 

 alternative means acceptable to the Administration shall be provided for 

 disposing of the oily-water ballast. 



Regulation 9 



Peak and Machinery Space Bulkheads, Shaft Tunnels, &c. 



(a) (i) A ship shall have a forepeak or collision bulkhead, which shall be 

 watertight up to the bulkhead deck. This bulkhead shall be fitted not less 

 than 5 per cent, of the length of the ship, and not more than 10 feet (or 3 05 

 metres) plus 5 per cent, of the length of the ship from the forward 

 perpendicular. 



(ii) If the ship has a long forward superstructure, the forepeak bulk- 

 head shall be extended weathertight to the deck next above the bulkhead 

 deck. The extension need not be fitted directly over the bulkhead below, 

 provided it is at least 5 per cent, of the length of the ship from the forward 

 perpendicular, and the part of the bulkhead deck which forms the step is 

 made effectively weathertight. 



(b) An afterpeak bulkhead, and bulkheads dividing the machinery space, 

 as defined in Regulation 2 of this Chapter, from the cargo and passenger 

 spaces forward and aft, shall also be fitted and made watertight up to the 

 bulkhead deck. The afterpeak bulkhead may, however, be stopped below 

 the bulkhead deck, provided the degree of safety of the ship as regards 

 subdivision is not thereby diminished. 



(c) In all cases stern tubes shall be enclosed in watertight spaces of 

 moderate volume. The stern gland shall be situated in a watertight shaft 

 tunnel or other watertight space separate from the stem tube compartment 

 and of such volume that, if flooded by leakage through the stem gland, the 

 margin line will not be submerged. 



Regulation 10 



Double Bottoms 



(a) A double bottom shall be fitted extending from the forepeak bulkhead 

 to the afterpeak bulkhead as far as this is practicable and compatible with 

 the design and proper working of the ship.
