ClassNK has validated the performance analysis of the automated kite system, ‘Seawing,’ developed by Kawasaki Kisen Kaisha, Ltd. and its French subsidiary, OCEANICWING S.A.S. This confirmation is encapsulated in a Statement of Fact (SOF), emphasizing the system’s potential in addressing environmental regulations and reducing fuel costs.
The implementation of wind-assisted propulsion systems (WAPS), including kite technology, is gaining traction as part of the maritime industry’s efforts to enhance sustainability. In response, ClassNK has been updating its ‘Guidelines for Wind-Assisted Propulsion Systems for Ships,’ first issued in 2019, to reflect operational insights and advancements. Notably, an Approval in Principle (AiP) for the ‘Seawing’ was granted in 2020, aligning with these updated guidelines.
In its recent assessment, ClassNK meticulously reviewed the performance analysis documents submitted by “K” LINE and OCEANICWING. This review utilized actual data from land-based tests of the ‘Seawing’ system, which features a 300 m² kite. ClassNK confirmed that the processes for verifying the system’s traction force and overall performance were robust and appropriate, reinforcing the credibility of the technology.
