ABSTRACT In order to study the combination effect of wind load and wave load on sea-crossing bridges, the observation data of wind and wave near the bridge site and the inversion data of wind and wave calculated by numerical model are used to fit the characteristic values of wind speed, wave...

... ABSTRACT An analysis method for the global structural strength of the cylindrical FPSO is established. The hydrodynamic model is developed by AQWA. The characteristic parameters suitable for cylindrical FPSO are proposed and the wave loads under different design wave parameters are obtained...

.... Since such a system is very stiff in the vertical degrees of freedom, it is sensitive to high-frequency loads which can generate a resonant response. The literature has indeed highlighted the contribution of high-frequency wave loads, such as third-order ringing loads, to the risk of slack-line events...
