Electric and hybrid propulsion systems

By moving to hybrid or electric propulsion, owners have inbuilt flexibility that can not only reduce emissions and optimise fuel consumption, but  are lighter and take up less space, with lower noise and vibration levels and reduced maintenance costs.

We optimise the system to match the vessels operating profile. The main systems are as follows:

The Rolls-Royce electric hybrid system delivers economy with flexibility for vessels that operate in a variety of modes, significantly reducing fuel consumption and emissions.

Electric systems are normally transformer-less with variable frequency motors on fixed frequency networks. This means they can also accommodate a battery power supply and can be plugged into a shore connection of variable frequency.

We select the best components from our broad supplier base and deliver a complete package. This approach relieves the shipbuilder of much of the technical risk and managing multiple equipment suppliers.
