One of the main benefits of battery-hybrid propulsion is the ability to optimize the loading of the prime movers for the generators to obtain maximum efficiency and reduce fuel consumption. This is especially beneficial for PSVs which have a typical operational profile that is divided between transit and dynamic positioning station-keeping operations.
