Function [Video Lesson]

An emergency generator on the ship provides power in case the main generators of the ship fail and creates a “dead or blackout condition”.


It is designed to provide electricity to essential systems and equipment, such as navigation lights, communication systems, and fire-fighting equipment, to ensure the safety of the ship and its crew.


The emergency generator is usually located in a separate room or compartment on the ship and is equipped with an automatic transfer switch (ATS) that detects a main power failure and automatically switches to the emergency generator.

According to general requirements, at least two modes of starting an emergency generator should be available. The two modes should be – battery start and hydraulic or pneumatic start.
