Hydroelastic behavior of a mat-type very large floating structure of arbitrary geometry

Applies ray theory to the estimation of the hydroelastic behavior of a very large floating structure (VLFS) since the method is easy to handle and is not time consuming. The theory itself is based on classical ray theory. The hydroelastic behavior of VLFS is treated as a wave propagation in the platform. One of the shortcomings of the ray theory is that the wave amplitude is suddenly changed along a ray that passes through the corner. The authors propose an application of the parabolic approximation to overcome it. Applying this method, a more realistic result of the amplitude distribution can be obtained. This method is applied to the 5000 m-class floating airport with the variation of the bottom topology, flexural rigidity, and the geometry of a VLFS
