Schottel’s Pump Jet for Finnish Research Vessel 

Schottel has equipped Finnish research vessel Aranda with a diesel-electric hybrid propulsion system. 

The 59.2 meter long and 13.8 meter wide ice-going research vessel is to be fitted with a 3 MW generator, the company informed.

While the conventional shafting is being retained, an electrically powered Schottel pump jet (SPJ) of type SPJ 132 RD with an input power of 400 kW will be installed as a new auxiliary propulsion unit.

The Aranda is owned by the Finnish Environmental Institute and is intended for year-round research and surveying missions.

Besides the propulsion assistance provided by the auxiliary drive, the SPJ is also used for dynamic positioning with an accuracy of half a meter, the company added.
