Abstract: (2604 Views)
The New Wave theory has recently applied for predicting wave forces on marine structures including offshore wind turbines. However, the validation of the theory in determining wave force has not been fully confirmed. However, the validation of the results for predicting stability parameters of marine structures is necessary. In the present article the prediction of the New wave theory of water surface profile, wave kinematics and offshore wind turbine monopile pier responses to the wave, including base shear, overturning moment and maximum displacement are compared to the experimental data and results from linear irregular wave time series generated from the wave spectrum. The comparisons show that the results are promising and in an acceptable level of accuracy for design purposes. Since the New wave theory takes very short time of processing in compare to real irregular time series, the theory is considered as the reliable substitute for prediction of wave forces on offshore wind turbines. The comparison with the results of the conventional 5th Stokes regular waves shows that the new wave theory is significantly more accurate in predicting wave kinematics and wave loads on offshore wind turbine monopiles.
