Rotor wind sails in the Baltic Sea
Since October, the “Copenhagen” is being refitted at the Remontowa shipyard in Gdansk (Poland). In addition to the regular inspection by the maritime classification society Lloyd’s Register, the ferry, which has been operating between Rostock (Germany) and Gedser (Denmark) since 2016, has been equipped with a steel foundation and additional cables to prepare the installation of a rotor sail that is planned for Q2/2020.
The Scandlines shipping company is investing in eco-friendly wind propulsion technology. The Norsepower rotor sail is a spinning 30 m high cylinder that harnesses wind power to thrust the ship forward. By installing the rotor sail, Scandlines will reduce the CO2 emissions of its hybrid ferry “Copenhagen” by 4– 5%.
Furthermore, the so-called closed-loop scrubbers, the ferry’s exhaust gas cleaning system that removes 90% of sulphur and soot particles from the ship’s emissions, were overhauled. With eight ferries, Scandlines carried 1.8 million cars and more than 700,000 cargo units on the Baltic Sea routes Puttgarden-Rødby and Rostock-Gedser in 2018. (fd)
