The 28-year-old research vessel Aranda is the first Finnish vessel to be modernized with a diesel-electric hybrid propulsion system. The 59.2 m long and 13.8 m wide ice-going vessel is to be fitted with a 3 MW generator. While the conventional shafting is being retained, an electrically powered SCHOTTEL Pump Jet (SPJ) of type SPJ 132 RD will be installed as a new auxiliary propulsion unit. It features an input power of 400 kW, is installed flush with the bottom of the research vessel and provides maximum thrust over the full 360° range, with no resistance, even in shallow water.
