ClassNK’s Senior Executive Vice President, Dr. Toshiyuki Shigemi and (right) K LINE Vice President Executive Officer, Mr. Atsuo Asano.
ClassNK has awarded an Approval in Principle (AIP) to K Line and Airseas for their Seawing automated kite system.
Kawasaki Kisen Kaisha, Ltd. (K LINE) confirmed that the AIP marked the completion of the initial design related to the kite structure and controls. The ship owner and operator confirmed that detailed engineering work was proceeding, with the target of installing and operating the first Seawing system aboard a K LINE vessel.
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.
The award was based on ClassNK’s Guidelines for Wind-Assisted Propulsion Systems for Ships, which was released in September 2019, and related regulations.
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.
ClassNK will continue to support the smooth implementation of new technologies through its role as a third-party certification body.
