The test was also the first aboard an LNG-fueled ship creating the first LNG-wind electric propulsion hybrid ship.
During the test, the Viking Grace was able to reduce its emissions, fuel burn, and fuel costs according to data released by Norsepower, developer of the rotor sail. They estimated the annual reduction in carbon emissions at approximately 900 tons, which they said was equivalent to reducing LNG fuel consumption by 300 tons per year…
