The most up-to-date of its kind - Passenger ship “MS Diamant” sets sail with parallel hybrid propulsion system from Siemens
Lake Lucerne, Sitzwerland. The passenger ship “Diamant” belonging to the Lake Lucerne shipping company SGV went into service in May 2017. Since its launch, the “MS Diamant” has been transporting up to 1,000 passengers per trip. This ultra-modern ship is impressive not just for its meticulously engineered design, but first and foremost for its innovative parallel hybrid drive concept. Most important part is the Siemens Siship EcoProp system, ensuring that the “MS Diamant” operates with minimal fuel consumption and material wear.
. The new passenger ship “MS Diamant” – diamond in English - just under 63.5 meters in length and 13.5 meters in width which has been operating a scheduled service on Lake Lucerne since May 2017. The ship, operated by the Lake Lucerne shipping company SGV, offers space for up to 1,000 passengers or 400 banquet guests. The “MS Diamant” was designed and built by SGV subsidiary Shiptec AG, and comes complete with design highlights such as a retractable upper deck and the “Nautilus Room”, whose underwater windows offer amazing views of the world below the surface, with shades of Jules Verne’s “20,000 Leagues under the Sea”. Not only the design but also the technology used in this new vessel are cutting edge. The state-of-the-art technology on board includes the parallel hybrid propulsion system from Siemens. Known as Siship EcoProp, this system is a meticulously engineered solution both ecologically and economically.
Secure supply even with high network loads
A part of the propulsion system comprises two permanently excited synchronous electric motors from Siemens, each with an output of 180 kilowatts (kW), which act as generators. Two additional diesel generator packages from Siemens in the bow of the ship which are not used in normal operation help to provide the assurance of a reliable supply to the on-board network in the event of high capacity utilization. This can arise, for instance, if the galley draws heavily on the power supply when preparing for a banqueting event. Two battery packs with 84 kilowatt hours (kWh) each ensures that every eventuality is covered at peak power periods, for instance during maneuvers or as a backup when the ship is stationary in dock. The hybrid propulsion system ensures that the machines always operate within the optimum load range, reducing wear and increasing their service life. In total, this propulsion solution allows fuel savings up to 17 percent during operation.
Innovative propulsion technology
The EcoProp system from Siemens is an innovative propulsion system which uses batteries to reduce fuel consumption and cut maintenance costs. The batteries and the boost function also permit the output of the main motors to be downsized, further reducing fuel consumption. A boost function allows the deliberately small-dimensioned diesel engine to be additionally supported by electric motor when maneuvering or changing direction. By delivering added torque, it boosts the function of the diesel engine when required.
The “MS Diamant” is a passenger ship belonging to the Lake Lucerne shipping company SGV which has been in scheduled service on the lake since the spring of this year.
Alongside the ship’s meticulously engineered design, the shining light of the “MS Diamant” is its ultra-modern technology.
