Viking Line: Viking Grace with Norsepower Rotor-Sail

Viking Line has installed a rotor sail on the LNG-fuelled Viking Grace, making it the first passenger ship in the world equipped with a rotor sail for the utilisation of wind power. LR approved the structure and the risk-assessment related to the installation of the sail in line with its Guidance Notes for Flettner Rotor Approval. The approvals were conducted to ensure that the Flettner rotor would not adversely affect the safe operation of the ship or the safety of the crew.    

In addition to the rotor sail solution installed onboard Viking Grace, Viking Line plans to use wind propulsion in the company’s new vessel, due to be operational in 2020. Built in China, the passenger ship will be equipped with two mechanical rotor sails supplied by Norsepower, doubling the wind power potential.
