Offshore Floating Photovoltaic structure (OFPV) represents a promising solar energy technology characterized by high conversion efficiency and suitability for large-scale deployment. However, the safety and economic synergy problems of floating structures restrict the industrialization and large-scale development of OFPV. We propose a novel OFPV with elastic connection and modularizable HDPE float blocks. The numerical wave tank is established by the turbulence model in FLOE-3D, based on the Navier-Stokes equations. Hydrodynamic analysis of the OFPV is conducted by using the Generalized Mode-Order (GMO) approach. Furthermore, the dynamic responses and mooring loads of the OFPV with elastic and rigid connections are compared. The results show that the average pressure of the photovoltaic support structure with the elastic connection is positively correlated with the wave height. The tension value of the elastic cable is higher at the outermost peak tension. The OFPV with the elastic connection structure has more obvious advantages in extreme wave state conditions than the rigid connection. This study provides theoretical support for the design and engineering application of OFPV.
