We applied the ray theory to estimating the hydroelastic behavior of VLFS since the method is easy to handle and not time-consuming. The theory itself is based on the classical ray theory. The hydroelastic behavior of VLFS is treated as wave propagation in the platform. The parabolic approximation is applied to smooth out the vertical elevation of the platform. Simple formulas for estimating the steady drift force and moment are derived. By employing these formulas and the ray theory, a quick computer code for estimating the steady drift force and moment acting on VLFS is developed. Some numerical results demonstrate the accuracy of this code, and the influence of nonuniform rigidity of the structure for the 5000-m-class floating airport is discussed.
