Characterization of Surface Motion of Submerged Unmanned Ship in Freak Waves Environment

open access: yesShanghai Jiaotong Daxue xuebao
When a ship encounters abnormal waves, the instantaneous impact will cause a drastic change in the wave load, potentially leading to capsizing in serious cases. To investigate the special ship type that can effectively withstand the impact of freak waves,
