Marine Shaft Generator System
The Marine Shaft Generator System is an energy-saving electrical generation system driven directly by the ship’s main propulsion shaft to produce onboard electrical power during sea voyages.
It reduces fuel consumption by using the main engine’s rotational energy instead of operating auxiliary diesel generators continuously.
Main Components
Shaft Generator
Main Propulsion Shaft
Step-Up Gearbox
Frequency Converter
Main Switchboard
Excitation Unit
Cooling System
Power Control Panel
Flexible Coupling
Synchronizing Unit
How It Works
The rotating propulsion shaft drives the shaft generator through a gearbox or direct coupling arrangement. Generated electrical power is controlled and synchronized with the ship’s electrical network through converters and switchboards.
Main Functions
Generates onboard electrical power
Reduces auxiliary engine fuel consumption
Improves energy efficiency
Supports main electrical distribution
Reduces engine room emissions
Common Problems
Voltage fluctuation
Bearing overheating
Coupling misalignment
Cooling failure
Synchronization faults
Marine Shaft Generator Systems are important energy-efficient marine power systems that improve fuel economy and reduce operational costs onboard ships.
