Wasaline LNG/battery-hybrid ferry: AC drives in hybrid power generation and propulsion

The cities of Vaasa in Finland and Umeå in Sweden ordered a new ro-pax vessel from RMC shipyard in Finland. The vessel underwent sea trials from June-August 2021 and will begin making regular trips between Vaasa and Umeå in autumn 2021. The vessel will be a clean LNG/battery hybrid with shore power. When entering and leaving the harbor, maneuvering will be battery-electric. The main electric propulsion is 2 x 6MW and battery power is 4 x 1.5MW. This will be a joint presentation by vessel owner Wasaline (optimized vessel), WE Tech Solutions (system) and Danfoss Drives (optimizing 35MW liquid-cooled drive systems).
