Hybrid shaft generator
The Hybrid Shaft Generator (HSG) drive provides electrical power to the vessel’s main swithboard by converting variable voltage and frequency input to fixed voltage and frequency output.
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.

CONVERSIONS, RETROFIT AND REFIT
We understand the importance of having the right parts, available in the right place, at the right time.
Ensure that your crew is properly and thoroughly trained. This will reduce operational risk, downtime and maximise return on asset investment.
