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...

... ABSTRACT In this paper, the computation of wave loads on a ship in an ice channel is carried out through a boundary integral equation method. The ice channel is confined between two semi-infinite ice sheets. The linearized velocity potential theory is used for the fluid flow and the thin...

... ABSTRACT This paper presents an experimental study on wave loads and hydro-elastic responses of a very large container ship in irregular waves. A segmented ship model with variable cross-sections backbone is newly designed to meet similarity conditions of vertical, horizontal and torsional...

... with the return period of 1 and 10 years based on the JONSWAP spectrum. The wave load on the containment boom can be obtained from the simulation and be imported into the in-place analysis of the anchor pile by SACS. The analyses can determine the overall behavior of the piles and establish the maximum stress...

... Abstract Most structures for floating solar photovoltaic systems consist of multiple modules which are made up of many buoys and connection beams. The hydrodynamic analysis on the total structure should be conducted to estimate wave loads on the structure precisely. However, considerable...
