Reducing GHG emissions using wind-assisted ship’s propulsion

  • 1 Nikola Vaptsarov Naval Academy, Varna, Bulgaria


International trade is still heavily reliant on oceangoing vessels and the noxious bunker fuel that feeds most ships’ massive diesel engines. Although shipping contributes relatively small shares of GHG emissions per unit of transport work, without further action, emissions from the sector would continue to increase. Therefore the maritime community and ship-owning companies are attempting to achieve “green shipping”. The revolutionary technology to use the wind for assisting the ship’ propulsion is one of best steps for decarbonisation of shipping. This innovative technology could bring considerable reducing fuel consumption and cost savings, improving the ships efficiency as well. There are different ways to utilize the wind power, as several kinds of rotors, sails, kites, etc, some of them already installed on commercial ships, some are still dreams. The aim of this paper is to present the basic essence of wind-assisted propulsion and the environmental impact of its use.
