K LINE and AIRSEAS have jointly obtained the Approval in Principle (AIP) from Nippon Kaiji Kyokai (ClassNK) for the design of the Seawing kite system which converts wind energy into propulsive force with its flying kite.

Seawing is a kite system which assists vessel propulsion by harnessing natural wind power through its dynamic flight. A simple switch launches or recovers the kite which unfolds, operates and refolds autonomously. The Seawing system collects and analyses meteorological and oceanic data in real-time, then adapts its flight to this information in order to optimize its performance as well as to ensure maximum safety.

Obtaining the AIP marks the completion of the initial design related to the kite structure and controls. Now the partners embark on further development and detailed engineering, with the target of installation and operation on the first K LINE vessel.

Through this project, K LINE will promote wind propulsion as an environment-friendly as well as economical measure, working towards zero emission ships.
