This study has developed a method for the motion prediction of a 10 MW floating wind platform under the action of waves
based on the Bi-directional long-short-term memory(Bi-LSTM) neural network. By simulating a 10 MW floating offshore wind power platform
wave and motion time series are obtained for a parameter sensitivity analysis. The simulation data are used to train the Bi-LSTM neural network framework and the parameters are then optimized. The results show that the developed Bi-LSTM model is highly effective in predicting the motion of the floating offshore wind platform under wave action in the next 1/3 time-length of the input data considering different wave heights and spectral peak frequencies. The prediction accuracy of the wave-induced heave and surge is as high as 95%. Therefore
the method proposed in this study has a strong ability to predict platform motion and is of great importance for the development of offshore wind energy.
