In this paper, a fast prediction model was established for ship motion and load based on Gated Recurrent Neural Networks (GRU). GRU neural network is a concise and efficient recurrent neural network that captures the temporal information of training samples to establish a model for predicting unknown samples. The forecast model consisted of two independent GRU neural networks used to predict ship motion and load respectively. The historical ship pitch and heave data were jointly used as the input of the motion prediction model to predict the ship pitch and heave in the next few seconds. The motion prediction results were used as the input of the load prediction model to achieve the prediction of the vertical bending moment in the midship. The method was validated through model test data, and the results showed that the prediction results at different lead times were in good agreement with the test results in terms of amplitude and phase, verifying the feasibility of the established ship motion and load prediction model.

本文基于门控神经网络(GRU)建立船舶运动与载荷快速预报模型,GRU神经网络是一种简洁高效的循环神经网络,通过捕捉训练样本的时序信息建立模型来预报未知样本。预报模型由两个独立的GRU神经网络组成,分别实现船舶运动与载荷的预报,将船舶纵摇和垂荡历史数据共同作为运动预报模型输入,预报得到未来数秒后的船舶纵摇和垂荡,并将运动预报结果作为载荷预报模型的输入,实现对船舯垂向弯矩的预报。通过模型试验数据对该方法进行验证,结果表明不同超前预报时间的预报结果与试验结果幅值和相位吻合较好,验证了所建立的船舶运动与载荷预报模型的可行性。
