Marine diesel engines are normally provided with automatic protection devices which operate in the event of abnormal conditions arising. Why would medium speed engines used for main propulsion normally only automatically slow down for certain abnormal conditions but automatically shut down for the same conditions when used to drive an alternator?
The gearbox and clutch of the propulsion system may be damaged if the engine suddenly stopped.
Sudden total loss of propulsive power may seriously endanger the vessel. This is a greater risk than engine damage.
Since the engine used for propulsion would usually be bigger the sudden stop would generate greater thermal stress which may damage the engine.
The vessel could continue to operate and manoeuvre without any electrical power at all as long as the main engine is still running.
