Where Emergency Generator Is Located?Īs per IMO SOLAS 74, the emergency source of power along with all necessary equipment, fuel tank, switch board and starting power shall be kept in one dedicated space. This is provided by the emergency generator that supplies both 220 and 440 V electricity to critical systems onboard via an emergency switchboard.
Such generators are used on a ship in event of main generator failure, engine room flooding, and starting the ship from blackout condition.Ĭritical systems and instruments such as the watertight door, navigation, alarms, communication equipment, steering gear, and emergency lighting need a relatively stable and reliable source of power. Further it should self start within 45 seconds of power failure. Electric, pneumatic, hydraulic or manual. Thus additional generator are provided on board dedicated for emergency services to make up for the sudden demand for emergency power.Īs per SOLAS regulation 19, they must include independent fuel supply and must have at least two modes of starting. What is The Purpose of Emergency Generator?įor safe operation of the ship you need continuous power supply to emergency services and instrument on board. They are also required to be fitted with safety devices to restrict them from running in parallel with the main generator under any condition.
There should be at least two different methods to start. Then there is the need to start anytime at 0☌ temperature. Then there is this requirement to self start within 45s of power failure.Īccording to SOLAS regulation an emergency generator must be fully operational for up to 10 degree of trim and 22 and a half degrees of list. Both the emergency generator and its switchboard is located in the same compartment.įurther, it should be capable of providing continuous power for at least 18 hours in case of cargo ships and 36 hours in case of passenger ships. This ensures there should be no further damage to the emergency generator from any major accident in the engine room.Īn emergency generator is connected to its own emergency switchboard connected in parallel with the main switchboard. Ideally above the uppermost continuous deck. This emergency generator must be located at a safe place away from the main power source. They should be self contained provided with independent fuel supply. Emergency Generator Starting Procedure SOLAS Regulations For Emergency Generator On ShipĪs per IMO SOLAS 74 convention each ships is required to have an emergency generator to maintain essential services.What is The Purpose of Emergency Generator?.SOLAS Regulations For Emergency Generator On Ship.In case of electric start the power source should be independent of the engine room power supply. The emergency generator supplies electric power to some of the most important instruments, devices, and machinery on a ship like the emergency pumps, emergency compressors, emergency lighting, emergency alarms, navigation equipment, ventilation fans, and emergency steering motor.Īn emergency generator can have an electric or crank start mechanism. Consisting of rotor, stator bush, fan and rectifier assembly along with its housing. The construction and operational features of an emergency generator are much like that of the main generator on board. Although the true power and size are determined by the size of the ship and their type container, tanker, or bulk carrier. Located outside the machinery space these are much smaller in size and capacity. It is part of the larger emergency machinery and systems installed on large ships related to the engine room. The role of the Emergency generator on the ship is to provide backup power for the emergency loads in case the main generator fails or blackout condition.
