technical description
The largely electrically operated ferry is a hybrid ship , as it receives the electrical power as drive energy from two lithium-ion batteries with a capacity of 530 kWh each or, alternatively, from diesel engines that drive two generators . The batteries typically charge in around five minutes during loading and unloading. The diesel generators are only used in ice conditions or in the event of a battery failure. The electric propulsion system for the ferry was supplied and installed by Siemens . The drive power of 2 × 900 kW is provided with an operating voltage of 690 V. Three diesel generators with 420 kWe each were installed for the internal power supply, and solar cells were also installed on the upper deck.
The ferry can carry around 90 cars on five lanes. The number of passengers and crew is 375 people.
