ClassNK grants AIP to “K” Line and Airseas for their Seawing kite system
“Seawing” is a kite system which assists vessel propulsion by harnessing natural wind power through its dynamic flight.
Leading Classification Society ClassNK has granted an Approval in Principle (AIP) based on its “Guidelines for Wind-Assisted Propulsion Systems for Ships” and related regulations to Kawasaki Kisen Kaisha, Ltd. (“K” LINE) and AIRSEAS SAS for their automated kite system “Seawing”.
According to an announcement by “K” Line and Airseas, ““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 company steps into 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 a environment-friendly as well as economical measure. K-Line therefore invests right now in this innovative “Seawing” kite technology in order to lead this transition towards zero emission ships. Its trustful collaboration with Airseas thus demonstrates once more its pioneering spirit and its engagement to contribute to the Society.
ClassNK released its Guidelines for Wind-Assisted Propulsion Systems for Ships in September 2019 in order to contribute to the safe integrity and design of this technology and the ships that are installed with it.
Upon receiving the application from “K” Line and Airseas, ClassNK reviewed the basic design of the kite system in line with relevant international conventions, ClassNK rules, and the above-mentioned guidelines. Following its successful completion, ClassNK granted an AIP for the basic design of the kite system.
