“…of each node can be obtained by modal analysis. Based on the three-dimensional hydroelastic theory [11], it is assumed that the fluid around the floating body is inviscid and incompressible. The fluid perturbation velocity potential is decomposed into the incident wave velocity potential φ 0 , the diffraction velocity potential φ D and the radiation velocity potential φ R .…”

“…However, with the development of the hydroelasticity theory [11][12][13][14][15] and the improvement of computer calculation abilities, the hydroelasticity method has become more widely used. Watanabe [16] summarized the hydroelasticity analysis method of VLFSs and pointed out that the application of the hydroelasticity analysis method in VLFSs is the future direction of development.…”

VLFSs (Very Large Floating Structures) are often assembled by multiple modules through connectors where the connector structure is prone to stress concentration. Therefore, the loads at the connectors have become a significant focus in VLFS design. In this paper, the FMFC (Flexible Module Flexible Connector) method, which can account for the elastic deformation of each module and the connector, is established in order to predict the coupling response of the connector and the platform. The finite element model of a dual-module transfer platform with a hinged connector is established and the modal shape characteristics of the entire structure are analyzed. The accuracy of the method is verified through a model test, where the model was scaled as 1:50. Furthermore, the RAOs (Response Amplitude Operators) of connector loads were calculated. It was found that the horizontal loads (along the x and y directions) were more sensitive to the wave direction. Furthermore, the wave direction where the maximum short-term significant value appears was not consistent with the direction of the maximum RAO. The loads response law of the VLFS with a hinged connector is summarized in this paper and provides a reference for the design of connectors.
