Blackout Test. Protections of an emergency diesel generator

Greetings! In the previous article on diesel engines, we discussed the protection of auxiliary diesel generators, which are most often tested on a ship during inspections in ports. In this article, we will consider the protections of an emergency diesel generator, as well as the procedure for testing a blackout of a ship's power plant.

At first I wanted to write that the protection of the emergency diesel generator (EDG) in ports is checked very rarely, but recently the Belgian PSC suddenly decided to check the protection of our emergency diesel. Therefore, in order to always be prepared for any checks, it is worth being aware of all the protections that this engine has.

Instruction for recovery of power generating plant after blackout

A blackout on a vessel refers to a complete loss of electrical power on the ship. This situation can arise from various causes, including mechanical failures, electrical faults, or human error. 

When a blackout occurs, it impacts all systems that rely on electrical power, which can include:

1. Navigation Systems: Loss of radar, GPS, and other essential navigation tools.
2. Communication Systems: Inability to use radios, satellite phones, and other communication devices.
3. Propulsion Systems: Potential loss of control over the main engines and steering mechanisms.
4. Lighting: Both interior and exterior lights may go out, causing visibility issues.
5. Safety Systems: Systems such as fire alarms, emergency lighting, and bilge pumps may become non-functional.
