Water wave impact on a wet deck is an important issue in ocean engineering, and the plate-shaped structure in the splash zone tends to suffer tremendous impact loads. This work presents a method for predicting the wave slamming uplift force on a fixed plate with different inclined angles. Both numerical simulation and the scale model test of the wave impact loads on an inclined plate were performed, and a good agreement was obtained. In addition, the influence of three important wave parameters on the slamming uplift force was systematically investigated: relative deck width B/L_S, relative wave height Δh/H_1/3, and the plate’s inclined angle α. The results indicate that the three parameters can significantly influence the wave slamming uplift force. Finally, a developed empirical equation is proposed for estimating the wave slamming uplift force on the inclined plate.

The present work proposed a novel modular structural system with central tension-leg platforms and outermost wave energy converters (marked as MTLPW). The hydrodynamic interaction effect and the mechanical coupling effect between the WECs and the TLP have been taken into consideration, and the effects of key design parameters of the WEC on the hydrodynamic characteristics of the MTLPW system have been clarified. The results indicate that the outermost WEC can significantly reduce the surge response of the central TLP and produce considerable wave energy. In addition, the effects of different connection types, pretension levels and additional heave plates on the hydrodynamic performance of the MTLPW system have been further investigated, and the results indicate that both the outermost WEC module and the additional heave plate can be promising and available for improving the hydrodynamic performance of the initial MTLPW system.
