New thrusters on Puttgarden-Rødby

– an important step on our way towards a greener ferry fleet and our Zero Emission strategy.

Next step towards our zero emission strategy is the exchange of all thrusters – the ships’ propulsion systems – on Scandlines’ four hybrid ferries on the route between Puttgarden (Germany) and Rødby (Denmark).  


The new thrusters will produce less underwater noise and further reduce CO2 emissions. We will – in collaboration with the German environmental organisation NABU – carry out measurements of how much we have been able to reduce the noise. Ships with less underwater noise can improve the conditions for the marine life in the Fehmarn Belt area – among these the harbour porpoises. The total investment in the new thrusters is more than 13 million EUR.

FS Schleswig-Holstein and FS Deutschland equipped with environmentally friendly propulsion system

As the first of the four Scandlines hybrid ferries on Puttgarden-Rødby, FS Schleswig-Holstein had its thrusters exchanged in the autumn of 2019. In April 2020, FS Deutschland was equipped with the new propulsion system.


The other hybrid ferries on Puttgarden-Rødby will be equipped with new thrusters in 2021. 

High tech pull thrusters instead of push thrusters


On the former push thrusters, the propeller was at the back, so the water needed to pass the thruster before it reached the actual propeller. 

We exchange these with high tech pull thrusters, where the propeller is at the front of the thruster, thus allowing a more homogeneous flow through the water. The new thrusters have four blades each, weigh 25 tons and have a diameter of 3.2 metres.
