Response Analysis Method of VLFS in Coastal Area Considering Topographical Effects on Wave Deformations

摘要

It is expected that VLFS (Very Large Floating Structure), especially pontoon type, will be installed in coastal areas. In coastal areas, wave deformations may play an important role. This means that we need to consider wave deformations due to topography when analyzing hydroelastic and hydrodynamic response of VLFS in coastal areas. Here, wave deformations include both linear phenomena and non-linear phenomena, such as reflection, shoaling, wave breaking, etc. In this paper, an approximate analysis procedure considering these wave deformations, whether they are linear or nonlinear, is proposed. The results by numerical analysis method are compared with the experimental results. In the experiment, reef model was examined. It is shown that the good estimation can be obtained through the procedure.
