The world's first diesel-electric main propulsion on river cruise vessel
The global AC drives manufacturer Vacon has delivered AC drives to MV
Viking Legend, the world's first river cruise vessel featuring a
diesel-electric propulsion system.
The diesel-electric propulsion system of the vessel makes the
maneuverability of the 135-meter-vessel easy on narrow rivers. It is
estimated that the vessel achieves a 20% boost in fuel efficiency in
comparison to any other river cruising vessel in the region. The ship
also provides a quieter ride for guests by using four smaller
propellers instead of two large propellers. Moreover, both engine
rooms have been insulated to further reduce noise and vibration.
The MV Viking Legend is the first river cruise vessel in the world
that is equipped with an integrated propulsion and network system,
based solely on inverter-driven asynchronous generators and
propulsion motors. The system uses Vacon's variable-speed AC drives,
and asynchronous generators and motors by AEM in Germany.
"The MV Viking Legend provides several new and remarkable technical
performance features which will not only significantly reduce fuel
consumption and CO2 and NOx emissions but will also improve the
maneuverability of the vessel and minimize cost for maintenance. We
are very excited that our technology is part of the world's first
diesel-electric river cruise vessel, which is also one of the largest
river cruise vessels in Europe," says Heikki Hiltunen, Executive Vice
President, Vacon Group.
At its overall length of 135 m, a width of 11.4 m, the Viking Legend
accommodates 189 passengers and 50 crew members. The vessel started
its maiden voyage from Amsterdam, the Netherlands, on 5 July 2009.
The integrated diesel-electric network and propulsion system was
developed and delivered by German-based e-powered marine solutions
GmbH & Co. KG (e-ms).
"The innovative network and propulsion topology of e-ms is based on
the cutting edge inverter technology from Vacon. It will now offer
new and interesting opportunities for the marine and offshore
industry. Thanks to the technically excellent, efficient and
comprehensive support from Vacon's engineers and my own team's
performance, it was possible to materialize this project within the
given time frame," says Mr Peter Andersen, Managing Director, e-ms.
The main propulsion system consists of four electrically-driven
Schottel rudder propellers. The required electrical power for
propulsion system and ship's network is provided by three diesel
generator-sets. These are dimensioned in a way (2 x 1000 kW, 1 x 560
kW) that sufficient power for the network and propulsion drives of
the MV Viking Legend will mostly be provided by two diesel
generator-sets only. However, reliable operation of the vessel with
only one diesel generator-set is also possible.
