“…The discrete-module-beam-bending based hydroelasticity method (Lu, et al, 2019, Sun, et al, 2018) is adopted to solve the hydroelastic response of a VLFS (which may be continuous, single-hinged or multi-hinged) under regular waves. The hydroelasticity method is derived in the framework of linear potential flow theory, assuming that (i) the fluid is inviscid and incompressible; (ii) the fluid motion is irrotational; and (iii) the motion of structure is small.…”

Floating offshore wind is a rapidly-growing technology attracting global interest. To date, most of the demonstrated concepts for offshore floating wind are based on a simple "one turbine -one platform" system, which may not be the most efficient approach for manufacturing, transportation and onsite installation. Very large floating structures (VLFSs), which allow for operation of multiple-turbines, may be an effective alternative to traditional floating foundations. However, the large bending moment caused by waves has been a major concern for a VLFS foundation. Adding hinges into the structure may help alleviate the bending moment. Based on the discrete-module-beam-bending based hydroelasticity method, the

“…One advantage of this approach is that it avoids the need for predetermination of the flexible modes, which may be difficult for complicated geometric (or connection) features of the flexible structure. Sun et al [7] extended the method proposed by Lu et al [6] to be applicable for the hydroelastic response of a hinged VLFS in waves (in frequency domain). Other applications of this method can be referred to Xu et al [8] and Zhang et al [9].…”

The hydroelastic response of a very large floating structure in regular waves suffering an external moving point load is considered. The linearized velocity potential theory is adopted to describe the fluid flow. To take into account the coupled effects of the structure deformation and fluid motion, the structure is divided into multiple segments and connected by an elastic beam. Then through adding a stiffness matrix arising from the elastic beam into the multiple bodies coupled motion equations, the hydroelastic response is considered. By applying the Fourier transform to the obtained frequency domain coefficients, the motion equation is transformed into the time domain and the external point load is further considered. The accuracy and effectiveness of the proposed method are verified through the comparison with experimental results. Finally, extensive results are provided, and the effects of the moving point load on the hydroelastic response of the very large floating structure are investigated in detail.
