Effect of Considering Wave Angles on the Motion Response of Oversized Floating Bodies in Offshore Airports under Irregular Wind and Wave Loads

Most existing studies are based on the hydroelastic response of oversized floating bodies under regular waves, ignoring effect wave conditions and incident angle vibration in real sea conditions. In this paper, stability performance a single module mega-floating body at an offshore airport was investigated by using STAR-CCM + numerical simulations specific model, with introduction parameters extreme random wind combined By comparing analyzing distribution characteristics action waves irregular wind, load, considering along flow direction, as well spreading direction vertical displacement value mooring, overall amplitude rigid displacement, elastic deformation influence both, law motion length body, we summarize dynamic airport. The results show that maximum hydro-elastic tends to appear head tail dominates role, all displacements cross is larger, stress area larger when between 15–30°. smaller angles 30–65°, ability bear load stronger. more sensitive angle, has less influence.
