Hybrid shaft generator

This allows the main engine and propulsion systems to operate at variable
speeds – including at optimal engine speed and propeller pitch – without
affecting the availability of electrical power on the vessel.

When it is able to operate at optimal engine speed and propeller pitch, a
vessel sails more efficiently (using less fuel) and smoothly (with minimum
propeller vibrations, which cause wear and tear).

By enabling the vessel to sail in this way, the HSG drive reduces fuel
consumption and emissions, and – by reducing vibrations – it also
reduces the cost of maintenance to the propulsion system.
Extra power or propulsion.
