Flettner rotor for Viking Grace
Helsinki-based Norsepower Oy Ltd has clinched a ground-breaking deal which will see its rotor sail solution installed on board the 57,565gt cruise ferry Viking Grace , making the vessel the world’s first LNG/wind electric hybrid ship. The Viking Grace , which is owned by Finland’s Viking Line and operates between the Finnish port of Turku and Stockholm in Sweden, is already one of the most environmentally friendly ferries in operation today. Now, the rotor sail installation will further reduce fuel burn and emissions, saving an estimated 900 tonnes of carbon emissions in a year, equivalent to cutting 300 tonnes of LNG consumption. The Norsepower rotor sail will be retrofitted during the second quarter of 2018 when one medium-sized unit, 24m in height and 4m in diameter, will be installed. The energy-saving devices can be retrofitted on existing vessels without off-hire costs, or fitted on board new ships during construction.
