In case of the failure of the main power generation system on the ship, an emergency power system or a standby system is also present.


The emergency power supply ensures that the essential machinery and system continue to operate the ship. Emergency power can be supplied by batteries or an emergency generator or even both systems can be used.


Rating of the emergency power supply should be made in such a way that it provides supply to the essential systems of the ship such as:

a) Steering gear system

b) Emergency bilge and fire p/p

c) Watertight doors

d) Fire fighting system

e) Ships navigation lights and emergency lights

f) Communication and alarm system.


An emergency generator is normally located outside the machinery space of the ship. This is done mainly to avoid those emergency situations wherein access to the engine room is not possible. A switchboard in the emergency generator room supplies power to different essential machinery.
