Norsepower Rotor Sail cuts fuel consumption on Viking Grace
Independent tests have shown that Viking Line’s Viking Grace could save up to 300 tonnes of LNG fuel per year in the long term by using Norsepower’s Rotor Sail technology. Viking Grace, which operates in the Åland archipelago between Finland and Sweden, was retrofitted with one medium-sized Norsepower Rotor Sail Unit in April 2018 , making her the first-ever cruise ferry to be powered by LNG fuel and wind-generated electricity. Developed as a modernised version of the Flettner rotor, the fully automated solution senses when the wind is strong enough to deliver fuel savings and automatically starts the rotors. According to analysis carried out by software and data analyst NAPA and technology provider ABB, there was an “evident change” in the propulsion power breakdown of Viking Grace, caused by the Rotor Sail.
Sailings cancelled due to oil leak
The scheduled sailings of the "Viking Grace" between Stockholm and Turk had to be cancelled from the evening of May 21, 2018, to the evening of May 22 due to an oil leakage in the hydraulic system. No spill was reported. Repairs were carried out in Turku. The leak had already been discovered the week before, and as the repair stop had been planned since, passengers could be contacted by Viking Line in advance on May 18. On May 22 at 8 p.m. the ship left Turku again after completion of repairs and arrived in Stocholm on May 24 at 6.30 a.m.
