SOLAS Requirements: Emergency Generator, Battery and Emergency Fire Pump

Emergency Generator & Fire Pump

SOLAS stands for Safety of Life at Sea, consist different regulations to set up a minimum standard for various equipment and machinery installed at the ship to ensure the safety of ship, machinery, and persons working onboard. Here in this blog, I am going to discuss SOLAS regulations for the Emergency generator, Battery, and Emergency fir pump.

SOLAS

Regulations

for

Emergency

Generator of the shipAll passenger and cargo vessels shall be provided with emergency sources of electrical power, for essential services under emergency conditions. Emergency generator and emergency switchboard of the ship should be located above the uppermost continuous deck, away from machinery space, behind the collision bulkhead. The main switchboard of the ship should not interface with supply, control, and distribution of emergency power. Emergency source of power should be capable of operating with a list of up to 22 ½ ° and a trim of up to 10 ° The generator should have independent fuel supply having flash point not less than 43°C. Emergency generator should be capable of giving power for the period of 18 hours for the cargo ship and 36 hours for the passenger ship. Emergency generator should start at 0°C and if temperature fall below this then there should be heating arrangement. Emergency generator should come on load automatically within 45s after the failure of main power supply. If the emergency generator fails to come on load the indication should be given to ECR. Emergency generator should have two different starting arrangement Primary may be the battery, should fully charge all time and capable of providing 3 consecutive Start. Secondary may be pneumatic or hydraulic, capable of providing 3 consecutive starts within 30 mint, and 1st start within 12 mint.

Regulation 42- the Emergency source of electrical power in Passenger Ship-

The emergency generator shall be automatically started and connected within 45 sec Capable of supplying simultaneously at least the following services for the period of 36 hours Emergency lightening (at the alleyway, stairways, and exits, muster and embarkation stations, machinery space, control room, main and emergency switchboard, firemen’s outfits storage positions, steering gear room) Fire detecting and alarming system Internal communication equipment Daylight signaling lamp and ship’s whistle Navigation equipment Radio installations, (VHF, MF, MF/HF) Watertight doors One of the fire pumps, emergency bilge pump The emergency generator shall be automatically started and connected within 45 sec A set of automatically connected Emergency batteries must be capable of carrying certain essential services for the period of 30 min Emergency Lighting Navigational Light Fire detecting and Alarm System Internal communication equipment Daylight signaling lamp and ship whistle

Regulation 43- the Emergency source of electrical power in Cargo ShipThe emergency generator shall be automatically started and connected within 45 sec Capable of supplying simultaneously at least the following services for the period of 18 hours Emergency lightening (at the alleyway, stairways, and exits, muster and embarkation stations, machinery space, control room, main and emergency

switchboard, firemen’s outfits storage positions, steering gear room) Navigational Light Fire detecting and Alarm System Internal communication equipment Daylight signaling lamp and ship whistle One of the fire pumps, emergency bilge pump Radio installations, (VHF, MF, MF/HF)

SOLAS Regulations for Battery of the ship – The ship where the emergency source of electrical power is an accumulator battery, it shall be capable of carrying loads without recharging and battery voltage throughout discharge period must be maintained within 12% above or below its nominal voltage. The battery system is automatically connected to the loss of main power. Batteries are required as the transitional power source for 30 min for following itemsFire detecting and fire alarm Navigational Light Emergency Lighting Internal communication equipment

List of equipment connected to the Emergency Power source on the shipEmergency Lighting Emergency steering motor Emergency fire pump Emergency air compressor Necessary machines to start one generator

Emergency alarms Engine room ventilation fan Watertight door Communication Fire detecting and fire alarm Bridge control console Cargo control console Engine room control console Battery charger for emergency generator Foam pump The rescue boat, life raft davit & Lifeboat Navigational and signal lights Battery charging panel The compressor of breathing apparatus GMDSS radio console Remove control Valves Navigational Equipment

SOLAS Regulations for Emergency Fire Pump The requirement for the number of fire pump In Passenger Ship of:4000 gross tonnage and upwards should have at least three fire pump and less than 4000 gross tonnages should have at least two fire pump In Cargo ship of:1000 gross tonnage and upwards should have at least two fire pump and less than 1,000 gross tonnages should have at least two power-driven pumps, one of which shall be independently driven.

Regulations for Emergency Fire Pump

All passenger ships of 1000 GRT and upwards and in cargo ships of 2000 GRT and upwards must have fixed emergency fire pump independently driven by a selfcooled compression ignition engine or an electric motor driven by electric power from the emergency generator Emergency fire pump must be located outside of the E/R room, in the steering flat, shaft tunnel or in the forward part of the ship. No direct access between the engine room and emergency fire pump. If access provided, it should be through an airlock arrangement. Emergency fire pump must have own suction, the total suction head should not exceed 4.5 meters under any conditions of list or trim of the ship. The capacity of the pump not less than 40 % of the total required the capacity of the fire pumps but in any case not less than 25 m3 / hr. Should be capable of delivering 2 jets of water with minimum pressure not less than 2.1 bar. The prime mover engine at that unit must be hand started and able to start with one man. If the pump is fitted above the water level, the self-priming arrangement must be fitted. If it is diesel engine driven, Easily started in cold condition (0°C by hand cranking), Fuel tank for engine shall contain sufficient to run on full load for at least 3 hrs Sufficient reserve fuel for 15 hrs, store outside the machinery space. Diesel power source of pump started in cold condition of 0° C by hand or by the power at least 6 times within a period of 30 minutes and at least twice within 1st 10 minutes. If motor driven: emergency power supply heating arrangement to be provided. Tank to have sufficient fuel for at least 3 hours and reserve fuel outside main machinery space to allow the pump to run for additional 15 hours. Isolation to allow the pump to run for additional 15 hours not more than 40 meters to pressure integrity of fire main system.(Diameter of fire main: sufficient for maximum discharge from 2 pumps operating simultaneously except for cargo ship the diameter need be sufficient for a discharge of 140 m3 / hour.
