Regulation 18 



Bilge Pumping Arrangements in Passenger Ships 



{a) Ships shall be provided with an efficient bilge pumping plant capable 

 of pumping from and draining any watertight compartment which is neither 

 a permanent oil compartment nor a permanent water compartment under 

 all practicable conditions after a casualty whether the ship is upright or listed. 

 For this purpose wing suctions will generally be necessary except in narrow 

 compartments at the ends of the ship, where one suction may be sufficient. 

 In compartments of unusual form, additional suctions may be required. 

 Arrangements shall be made whereby water in the compartment ma> find 

 its way to the suction pipes. Where in relation to particular compartments 

 the Administration is satisfied that the provision of drainage may be 

 undesirable, it may allow such provision to be dispensed with if calculations 

 made in accordance with the conditions laid down in paragraph ib) of 

 Regulation 7 of this Chapter show that the safety of the ship will not be 

 impaired. Efficient means shall be provided for draining water from insulated 

 holds. 



(/?) (i) Ships shall have at least three power pumps connected to the bilge 

 main, one of which may be attached to the propelling unit. Where the 

 criterion numeral is 30 or more, one additional independent power pump 

 shall be provided. 



(ii) The requirements are summarised in the following table: —
