Where On The Ship Is The Emergency Generator Located?
The Emergency Generator Is Located Remotely From The Engine Room, Usually On The Accommodation Deck Or At Weather Deck Level Or Above.
 
What Are The Essentials Supplied By The Emergency Switchboard?
Essentials Are:  Emergency Lighting, Alarms, Communications, Navigational Equipments, Watertight Doors And Other Services Necessary To Maintain Safety And To Permit Safe Evacuation Of The Ship By Lifeboats.  Also You Will Find That A Steering Gear Motor, Emergency Air Start Compressor And Emergency Fire Pump Motor Are Supplied From The Emergency Switchboard.
 
Explain How The Emergency Generator Starts Up In The Event Of Total Power Failure?
The Start-up Of The Emergency Generator Is Initiated By An Electrical Relay, Which Monitors The Normal Mains Power Supply.  Falling Mains Frequency Or Voltage Causes The "start-up" Relay To Operate The Generator Starting Equipment.  The Prime Mover May Be Electrically Cranked From It's Own 24V Battery And Starter Motor Or Air Started From It's Own Air Reservoir Fitted Local To The Generator Engine.  A Manual Start-up May Also Be Initiated By Push Buttons In The Main Control Room And In The Emergency Generator Room.
Also When Power Loss Occurs, The Breaker Feeding The Emergency Switchboard From The Main Switchboard Opens.  This Breaker Is Interlocked With The Emergency Generator Breaker, Which Is Normally Open Under Normal Circumstances, But In The Event Of Total Power Failure, This Breaker Will Close When The Breaker Feeding The Emergency Board From The Main Board Opens.  Thus The Emergency Generator Will Feed The Emergency Switchboard.
 
What Is Done To Ensure The Emergency Generator Is Always Available And Will Start?
The System Should Be Checked Regularly And Operated Weekly To Ensure It's Availability If Required.  Fuel Tanks Should Be Kept Full, Ample Cooling Water In Radiator Cooling System And Starting Equipment Should Be Functional, I.e. Batteries Should Be Fully Charged Or Air Receivers Full.
