51 Cargo pump

51. (1) Except as otherwise provided in paragraph (2) of this Rule, in every tanker of Class VII(T) of 500 tons or over, each cargo pump room and each pump room having a similar hazard shall be provided with at least one of the fixed fire extinguishing systems required by Rule 33 (1) of these Rules and which shall be operated from a readily accessible position outside the pump room, provide that where the fixed extinguishing system is a gas system:

( b ) Any diesel driven power source for the emergency fire pump shall be capable of being readily started in its cold condition down to a temperature of 0°C by hand cranking. Where lower temperatures are likely to be encountered, heating arrangements acceptable to the Minister shall be provided. Where hand cranking is impractical alternative arrangements other than by hand shall be such as to enable the diesel driven power source to be started at least 6 times within a period of 30 minutes, and at least twice within the first 10 minutes.

( c ) Any service fuel tank for the diesel driven power source referred to in sub-paragraph (b) of this paragraph shall contain sufficient fuel to enable the emergency fire pump to run on full load for at least three hours and sufficient reserve of fuel shall be available outside the main machinery space to enable such pump to be run on full load for an additional 15 hours.

In cases where such access by means of an airlock is provided, a second means of access to the space containing the emergency fire pump and its source of power shall be provided.

( g ) Ventilation arrangements to the space containing the independent source of power for the emergency fire pump shall be such as to prevent the possibility of smoke from a machinery space fire entering or being drawn into that space.

( a ) where only one pump is required by the Rules, that pump, or

( b ) where two such pumps are so required, both pumps operating simultaneously, or

( c ) where more than two such pumps are so required, the two largest of such pumps operating simultaneously;

provided that in any ship other than a passenger ship the diameter of the fire main and of the water service pipes shall be required to be sufficient only for the discharge of 140 cubic metres per hour.

(3) ( a ) Where any ship is required by these Rules to be provided with appliances capable of producing two jets of water under the conditions required by these Rules, hydrants sufficient in number shall be so positioned as to enable at least two jets of water, not emanating from the same hydrant, one of which shall be from a single length of hose, to reach any part of the ship normally accessible to the passengers or crew while the ship is being navigated and to any store room and any part of any cargo space when empty, except that in any special category space or ro/ro cargo space two jets shall reach any part of the space, each from a single length of hose. Such hydrants shall be positioned near the accesses to the protected spaces.

( b ) Where any ship is required by these Rules to be provided with appliances capable of producing one jet of water under the conditions required by these Rules, hydrants sufficient in number shall be so positioned as to enable one jet of water from a single length of hose to reach any part of the ship normally accessible to the passenger or crew while the ship is being navigated and any store room and any part of any cargo space when empty.
