Feasibility Study of Wing Sail Technology for Commercial Ship
Keywords:Wing-sail, Fowler flap, Fuel saving, CO2 emission, Ship stability
In the 21st century, the growth in the price of fossil fuels and climate change prompted the shipping industry to consider alternative methods to minimize the use of fossil fuels. Wind-assisted propulsion system, in this regard, is quickly becoming one of the most popular and efficient methods of reducing both fuel usage and carbon dioxide emissions from ships. This study aims to perform numerous analyses on a model of an oil tanker that is outfitted with several solid vertical sails on its deck. ANSYS Fluent platform is used to run the simulations and the thrust produced by the solid sails at various apparent wind angles is determined. The fuel consumption is then calculated for a particular voyage of that tanker before and after installation of sail to find out the percentage of reduction in fuel consumption. It is proven that using the wing-sail with or without a fowler flap can save fuel and reduce carbon dioxide emissions by 1.64 to 2.08 percent, respectively. In addition, the ship's intact stability has been investigated using MAXSURF software and validated against the fulfillment of the weather criteria. The selected ship was found to have good stability after the installation of wing sail.
