Regulation

The SOLAS regulations also require that emergency generators be tested regularly to ensure they are in good working condition. The IEC’s International Standard for Safety of Electric Power Systems in Ships (IEC 60945) sets out the technical requirements for emergency generators on ships.

 

These requirements include specifications for the generator’s power output, voltage, and frequency, as well as the type of fuel it uses. In addition to these international regulations, ships are also subject to national and regional regulations regarding emergency generators.

 

For example, the United States Coast Guard (USCG) has its own regulations for emergency generators on ships that operate in US waters. These regulations include requirements for the generator’s power output, fuel type, and testing schedule.

 

The following are the important requirement for emergency generators used onboard ships:

  • The emergency electrical power-providing generator shall be driven by a suitable prime mover having independent auxiliary systems, which may consist of fuel, ventilation, lubrication, cooling, etc.
  • The fuel used in the emergency generator prime mover must have a flash point of > 43° C
  • The prime mover of the emergency generator shall be started automatically once the main source of the electrical power supply fails.
  • If the emergency generator does not start or does not take the load off the emergency switchboard connections, an indication shall be given in the engine room or at a manned control station
