COMPOSITE 2D/3D HYDROELASTIC-ANALYSIS METHOD FOR FLOATING STRUCTURES

This paper presents a new approach to the analysis of the wave-induced, hydroelastic response of floating, slender structures. The approach combines a three-dimensional (3D) structural model with fluid forces from two-dimensional (2D) potential theory, known as strip theory. The method permits direct computation of three-dimensional structural response; but, the large computational effort of three-dimensional hydroelasticity is avoided because of the application of the two-dimensional fluid model. The composite 2D/3D method is verified by satisfactory agreement with results from full 3D hydroelasticity for a small water-plane area twin-hull ship. Because the computational effort is significantly less, the authors expect the method to be particularly useful in the design of ships.
