- Abstract
Marine operations, engineering activities, and transportation are highly influenced by sea waves, and accurately predicting the 2D wave field is crucial for ensuring safe and efficient project execution and avoiding the sea wave disaster. While existing deep learning applications for wave height prediction primarily focus on single-point forecasts, it's important to note that single-point data may not capture the overall regional trends effectively. Therefore, this paper establishes two spatiotemporal network models based on LSTM cells for Lianyungang Port and compares their performance. The results demonstrate that PredRNN, with its newly designed spatiotemporal memory cell which is able to deliver memory states through layers and laysers on current node and can learn the short-term non-linear variation, outperforms ConvLSTM, especially when dealing with unbalanced input samples. With the forecasting leading time increasing from 6h to 12h the correlation coefficient of PreRNN is over 0.9, ConvLSTM decreases to 0.849. Under the lower accuracy of input samples condition, PredRNN also performs better. In summary, PredRNN is less affected by the quality of input samples, which has engineering value in significant wave forecasting for marine operations.
