Viking Princess

70-100 m

500-1000 kWh

Viking Princess was the first PSV to use LNG and has now also been equipped with batteries. Due to the use of Corvus Orca Energy batteries, the vessel could get rid of one LNG motor and is now saving 14 % each day and night in fuel, which equals one ton of fuel per 24 hours!
