... mode shapes are determined through the application of a FEM based structural model. The diffraction/radiation problem is solved using the boundary integral equation method. Focus is given on the flexible modes' generalized hydrodynamic forcing and responses, the spar's hydroelastic response...

... ABSTRACT In this paper, linear and frequency-domain hydroelastic analysis is performed for investigating the behavior of a free floating, annular and flexible plate. A "dry" mode superposition approach is utilized, where the flexible mode shapes are determined through the derivation...

... generalised mass. The natural frequencies of the first four antisymmetric flexible modes of the two VLFS are shown in Table 2. Results obtained from the two- and three-dimensional structural idealisations of the pontoon are denoted by Beam(FD) and SHELL63, respectively. These are in good agreement, especially...

.... This paper is concerned with the optimal allocation of flexible modes of motion for a mat-like large circular floating island with ring-shaped breakwater. The base-mat is idealized as an elastic circular plate. The breakwater which is located around the circumference of the base-mat is idealized...
