Converting cargo ships to environmental friendliness through a new type of sail.. Know the details


A French company for cargo ships revealed a new system for sails that deal with air in a way that makes them environmentally friendly, as it reduces the need for fuel, increases the efficiency of cargo ships while reducing greenhouse gas emissions, and the sails automatically spread to take advantage of the winds at sea, and then retract with the same speed, making it a “plug and play” system.

According to the British newspaper, “Daily Mail”, this means that crew members will not have to become expert sailors to operate hybrid ships, and that the sails can improve ships’ fuel efficiency by up to 20%.

The company revealed the Wing Sail Mobility (WISAMO) project at the Movin’On Global Sustainable Mobility Conference 2021, it is a system of winged sails that can be retrofitted on both commercial vessels, especially bulk carriers, oil and gas tankers and yachts.

A joint project with a team of Swiss inventors, the sails will use wind energy to increase the efficiency of existing oil-powered engines.

“The advantage of wind propulsion is that wind energy is clean, free, global and completely uncontroversial,” said world-renowned captain Michel Desjouio, “and it provides a very promising way to improve the environmental impact of merchant ships.”

New Atlas reports that the new sails automatically reposition to maximize wind conditions, and when not in use, the sails deflate and remain on deck.

The company said that the design of the double-sided system is an improvement over conventional flat sails, and the telescopic mast is retractable, allowing ships to enter ports and transit easily under bridges.
