Abstract The very large floating structure (VLFS) deployed near seashore, islands and reefs are always exposed to the extremely complex encountering waves. Traditional methods with homogeneous wave inputs are not applicable for the hydroelastic analysis of this type VLFS. In this paper, the authors carry out a numerical and experimental investigation on hydroelastic responses of an 8-module VLFS near a typical island. A direct coupling analysis method is established on the basis of the Boussinesq equation and RANKINE source method. The detailed theoretical derivation, numerical method and relevant calculation program THAFTS-BR are presented. Wave propagation near the island, motions and connector loads of the VLFS deployed a typical island are investigated based on the numerical method and model tests. Several useful conclusions are obtained, which can provide a reference for the analysis of dynamic responses, design and construction of the floating structures near islands and seashores.
