AROSA AQUA – an innovative propulsion system for a new generation of river cruise ships!

Due to the stringent requirements of the owner, AROSA Flussschifffahrt GmbH, in terms of sound levels in the cabins and reduced energy consumption, newbuilding 514 from NEPTUN Werft GmbH was designed with a new propulsion concept in the stern.

The direct diesel-driven azimuthing SCHOTTEL Pump-Jet SPJ of type 82 RD, approved for use as an independent propulsion system and installed in the bow, has already found its way into other new river cruise ships.

Due to its compact design and extremely low structure-borne noise levels, and its outstanding ability to generate virtually constant thrust at any speed, it is encountering great interest in this market segment and has already managed to boost its market share considerably.

The main propulsion system, consisting of 4 SCHOTTEL Twin Propellers of type STP 200 with highly elastic bearings, driven by 4 VOLVO PENTA D 12 diesel engines with a power rating of 331 kW at 1800 r.p.m., is unique and is making its inland shipping debut in this vessel.

The next newbuilding, 515, also for AROSA Flussschiff GmbH, is being fitted with the same propulsion concept. Meanwhile, a river cruise ship from another renowned shipping company has also entered service with four STP 200 propulsion systems.
