ROTOR SAILS AS A PERSPECTIVE SHIP POWER PLANT

Abstract

Modern requirements for the environmental friendliness of ships require an increasing involvement of rotor sails. Rotor sails are an effective tool to save fuel and reduce carbon emissions. In article researched the possibility of rotor sails depending on the wind direction and wind speed in the region. For the experiment were taken 2 ships and wind force moments. The world’s leading supplier of auxiliary wind power plants Norsepower Oy Ltd. successfully inserts rotщк sails on vessels of various types. Thanks to this technology, the vessel can significantly save fuel and reduce emissions. According to the analysis carried out by Norsepower and Sea-Cargo, new installation on board the ship “SC Connector” can provide a reduction in fuel consumption and its cost, as well as carbon dioxide emissions to 25%. the appropriate wind, the vessel will maintain a constant speed only by sail. In the process of decarbonizing the world fleet and achieving the IMO goals for 2030 and 2050, the marine industry is actively looking for solutions to reduce emissions, so the developments of the past are useful. Rotor sail Norsepower – it is an upgraded version of flatner rotor or "turbosail", which rotates based on the Magnus effect, using wind energy to move the vessel Modern development is fully automated, the system itself determines when the direction and speed of the wind is sufficient to provide fuel savings and the necessary thrust, after which the rotor sails start automatically. The article discusses sea passages across the oceans, wind phenomena and features of rotor sails work during these passage. Rotor sails are original and very effective in terms of fuel economy by ship power plant. Proposed the best variation of localization rotor sails depending on the ship construction features. This article is a theorical base for the installation of rotor sails on large vessels.
