The kite creates a "revolution" in reducing emissions
"Seawing", a giant 250m² parafoil kite, was tested at sea for the first time. It successfully towed Ville de Bordeaux, a cargo ship with a gross tonnage of 21,528 tons, according to Interesting Engineering.
“We are proud to have a solution that can help ships reduce emissions right now. At the same time, accelerate the decarbonization process of the maritime industry in the coming years," Mr. Vincent Bernatets, CEO of Airseas, declared.
He also said the company has worked with several large shippers and installed a number of Seawing propulsion systems for cargo ships.
Currently, Airseas has completed the installation of the first Seawing system for customer "K" Line (Kawasaki Kisen Kaisha, Ltd).
This system was installed on a Capesize bulk carrier in December 2022. This is the first of 5 K Line ships equipped with Seawing.
The 210,000 DWT bulk carrier powered by LNG and built at Nihon Shipyard will be the second ship with a Seawing. Installation will take place after the ship is delivered in 2024.
What is Seawing giant kite technology?
Seawing combines kite technology with an automated flight control system created by the aerospace industry to capture wind energy. The system reduces ships' emissions and fuel consumption by an average of 20 percent, according to the company.
Seawing technology is bolted to the vessel and takes up little deck space. It can be placed on most types of ships, is not restricted by height limits and does not hinder cargo operations.
A static kite or sail only has 1/10 the traction of a Seawing, which flies flexibly at a speed of more than 100km/h on a figure-8 trajectory. The kite flies 200m high in the air to catch stronger winds. , more stable.
According to the International Windship Association, by the end of 2023 there will be 50 ships powered by wind.
