As per SOLAS chapter 2-2 regulation 10
>Not less than 40% of the total capacity of main fire pump
>Not less than 25 cu. m/hr (in any case)
>Not less than 40% of the total capacity of main fire pump
>Not less than 25 cu. m/hr (in any case)
Location:
> Located outside the engine room into the shaft tunnel or in the forward of the ship. There should not be any direct access between engine room and the fire pump. If there is access from engine room then means of Air Interlock should be
provided.
>Pressure:
for passenger ships:
4,000 gross tonnage and upwards 0.40 N/mm2
less than 4,000 gross tonnage 0.30 N/mm2
.2 for cargo ships:
6,000 gross tonnage and upwards 0.27 N/mm2
less than 6,000 gross tonnage 0.25 N/mm2
Cargo ships:-
4,000 GRT & above = 0.27 N/mm2
less than 4,000 GRT = 0.30 N/mm2
less than 4,000 GRT = 0.30 N/mm2
Passenger ships:-
6,000 GRT & above = 0.27 N/mm2
less than 6,000 = 0.25 N/mm2
Must Read: >Regulations For Emergency Generator
>Jet/ Capability:
At least 2 jets not emanating from the same hydrant, using one hose length should be able to give a throw of 12 m.
>Sea suction valve:
Should be able to be operated from near the emergency fire pump.
>Suction head:
Total suction head not to exceed 4.5 m under all conditions of list and trim
>Drive type:
Generally diesel engine driven-should be able to started by hand cranking to 0*C ambient temperature.
less than 6,000 = 0.25 N/mm2

DeletePlease mention the location of emergency fire pump. Which is placed on main deck and there should not be any direct access from engine room to emergency fire pump.
ReplyDeleteyes u r correct
DeleteAs per SOLAS chapter 2-2 regulation 10 2.1.6 Pressure :
ReplyDelete.1 for passenger ships:
4,000 gross tonnage and upwards 0.40 N/mm2
less than 4,000 gross tonnage 0.30 N/mm2
.2 for cargo ships:
6,000 gross tonnage and upwards 0.27 N/mm2
less than 6,000 gross tonnage 0.25 N/mm2
Please correct if i make any mistake. This is from 2009 consolidated edition.

DeleteDiameter of Fire main shouldbe suffficcient for the discharge from 2 pumps operating simultaneously except for cargo ships the diameter need to be sufficient for a discharge of 140 m3/h
ReplyDeletelocated outside the engine room into the shaft tunnel or in the forward of the ship. there should not be any direct access between engine room and the fire pump and IN CASE there is then means of Air Interlock should be provided
thanks for your valuable comments
Deleteif the emcy fire pump is Diesel driven:-
ReplyDelete1. easily start in cold condition(at temp of zero degrees and with hand cranking)
2. fuel tank should contain enough oil to run it for a minimum period of three hours
3. Sufficient fuel reserve for 15 hours should be available and should be located outside the Engine Room Machinary Spaces

Deletethe pressure is wrong here
ReplyDeletefor cargo ships:
6,000 gross tonnage and upwards 0.27 N/mm2
less than 6,000 gross tonnage 0.25 N/mm2
yes corrected.. thanks for your valuable input...
