“For many years we have recognised the gap in the propulsion market for smaller pods, including ice-class, in the 1.5MW to 7MW power range,” said Per Nahnfeldt, R-R’s gm for Electrical Propulsion.
The ELegance pods – one with an open propeller, the other ducted – “complement our broad product portfolio and sit well with our range of frequency drives and electrical systems,” he adds. “We can now provide a complete fully electric propulsion package.”
The pods are based on Permanent Magnet technology and feature a ‘twin tail’ concept to further improve efficiency while significantly reducing cavitation-induced noise and vibration.
“A new integrated hull fitting interface also allows a compact head-box to be used, which minimises drag and further improves hull efficiency,” said Nahnfeldt, “This also allows the height and tilt of the pod to be adjusted, allowing operators to select the optimum propeller size for the vessel.”

The 1A Super and Polar Code 6 ice class pods have also been designed with ease of installation and maintenance in mind. An environmental focus also means that a sealing solution has been selected with no oil-to-sea interfaces, any leak being fed into a dedicated sump connected to the ship’s bilge system.
