Data-driven Approach of Ship Dynamics in Maneuver: Principle and Application
Hydrodynamic Testing and Evaluation Laboratory (HTEL)
Dept. of Autonomous Vehicle System Engineering
Chungnam National University
For the design and operation of autonomous vessels, a comprehensive understanding of the vessel's dynamics under various maneuvering conditions is essential. This is more challenging compared to previous methods of predicting ship maneuverability, which mainly focused on evaluating IMO criteria through controlled sea trials. In this seminar, the principles of ship maneuvering will be introduced, along with data-driven modeling techniques based on free-running model test results. This approach, developed using traditional principal component analysis and regression, incorporates technical efforts to address the nonlinearities in ship dynamics.
Dr. Jeonghwa Seo completed his Ph.D. in Naval Architecture and Ocean Engineering in 2016 at Seoul National University, Korea, with a focus on experiments related to turbulence structure under violent free-surface conditions. After two years as a post-doctoral researcher, he joined the Department of Naval Architecture and Ocean Engineering at Chungnam National University, which has since been restructured into the Department of Autonomous Vehicle System Engineering. His research primarily focuses on the design and analysis of towing tank model tests in naval contexts, and more recently, on analyzing operational data from real fleets with physical explanation.
