Installation of “Seawing”, an Automated Kite System Utilizing Natural Energy

Kawasaki Kisen Kaisha (“K” Line) has decided to install the automated kite system “Seawing” * 2 developed by AIRSEAS * 1 which is a spin off of AIRBUS SE, a major aircraft manufacturer, on a large bulk carrier owned by our company.

“Seawing” is mounted on the bow of the vessel and is unfolded by a simple operation from the bridge under certain conditions of wind power and wind direction which assists propulsion power of the vessel by effectively utilizing the wind’s force.

During the trial, “K” Line carried out intense assessments of “Seawing”’s performance and innovative technology for two years with the close cooperation of AIRSEAS and confirmed that this system can greatly contribute to the reduction of the environmental load associated with the ship’s operation.

In one case, a bulk carrier reduced emissions by more than 20%, which is equivalent to about 5,200 tons of CO2 annually. In addition, Kawasaki Kisen Kaisha and AIRSEAS will continue cooperation to further improve this solution by utilizing the operation and performance data obtained from the ship operation and performance management system “Kawasaki Integrated Maritime Solutions”*3 installed in our fleet vessels.

“K” Line will continue to work on CSR activities for environmentally friendly innovations to achieve our “K” LINE Environmental Vision 2050*4 target and the GHG reduction of IMO, through the studies, developments and installations various environmental improvement technologies such as “Seawing”.


AIRSEAS is a spin-off of AIRBUS which combines aeronautical know-how in modelling and control laws with maritime technology to bring a game changing energy efficiency solution to shipping.

*2: Seawing

Seawing combines aeronautical know-how with maritime technology to create a breakthrough in the maritime transportation sector. A simple switch launches or recovers the kite which unfolds, operates and refolds autonomously. The system collects and analyses meteorological and oceanic data in real-time. Seawing adapts to this information in order to optimize its performance as well as to ensure maximum safety.
