Hydroelastic model investigates responses of VLFS under wave-current interactions, suggesting implications for engineering.
The present study develops a hydroelastic model of a very large floating structure (VLFS) under combined wave-current conditions using the Discrete-Module-Beam (DMB) method. This approach integrates multi-body hydrodynamics with the Euler-Bernoulli beam assumption to facilitate hydroelastic analysis. To ensure the accuracy of the proposed method, validation is conducted against both experimental data and existing numerical results. The hydroelastic behavior of the VLFS under wave-current interactions is then investigated, considering several influencing factors, such as the current velocity, wave incident direction, elastic modulus, and draft. The results demonstrate that the wave incident direction and elastic modulus have a more pronounced influence on the hydroelastic response of the VLFS compared to current velocity and draft. The methodology, analysis, and findings presented in this study could provide some insights for the engineering applications of the VLFS.
