SAFETY OF LIFE AT SEA 



C45 



(iii) Sanitary, ballast and general service pumps may be accepted as 

 independent power bilge pumps if fitted with the necessary connections to 

 the bilge pumping system. 



(c) Where practicable, the power bilge pumps shall be placed in separate 

 watertight compartments so arranged or situated that these compartments 

 will not readily be flooded by the same damage. If the engines and boilers 

 are in two or more watertight compartments, the pumps available for bilge 

 service shall be distributed throughout these compartments as far as is 

 possible. 



id) On ships 300 feet (or 91-5 metres) or more in length or having a 

 criterion numeral of 30 or more, the arrangements shall be such that at least 

 one power pump shall be available for use in all ordinary circumstances in 

 which a ship may be flooded at sea. This requirement will be satisfied if: — 



(i) one of the required pumps is an emergency pump of a reliable 

 submersible type having a source of power situated above the 

 bulkhead deck; or 



(ii) the pumps and their sources of power are so disposed throughout the 

 length of the ship that under any condition of flooding which the 

 ship is required to withstand, at least one pump in an undamaged 

 compartment will be available. 



{e) With the exception of additional pumps which may be provided for 

 peak compartments only, each required bilge pump shall be arranged to draw 

 water from any space required to be drained by paragraph (a) of this 

 Regulation. 



(/) (i) Each power bilge pump shall be capable of giving a speed of water 

 through the required main bilge pipe of not less than 400 feet (or 122 metres) 

 per minute. Independent power bilge pumps situated in machinery spaces shall 

 have direct suctions from these spaces, except that not more than two such 

 suctions shall be required in any one space. Where two or more such suctions 

 are provided there shall be at least one on the port side and one on the 

 starboard side. The Administration may require independent power bilge 

 pumps situated in other spaces to have separate direct suctions. Direct 

 suctions shall be suitably arranged and those in a machinery space shall be of 

 a diameter not less than that required for the bilge main. 



(ii) In coal-burning ships there shall be provided in the stokehold, in 

 addition to the other suctions required by this Regulation, a flexible suction 

 hose of suitable diameter and sufficient length, capable of being connected 

 to the suction side of an independent power pump.
