Aurora Botnia departs and arrives precisely on time. The vessel is powered by both electricity and liquefied biogas (LBG). When departing from Vasa, it had 6Mwh of electricity available and 30 cubic metres (m³) of LGB. Upon arrival to Umeå, it had 2 MWh of electricity available for maneuvering in and out of the ports, along with 10 (m³) of LBG. Upon departure from Umeå, these levels were reduced to 1 MWh of electricity and 5 m³ of LBG.
Berthing

The tractor, powered by diesel, began the task with 300 liters of fuel and completed the three round trips with 250 liters remaining.
