Abstract

In order to effectively achieve a real-time prediction of jacket platforms dynamic response under wave load,the dynamic response prediction method combining one-dimensional convolutional neural network and gated recurrent composite neural  network(1DCNN+GRU) was proposed. Based on the SACS program platform,the numerical calculation model of single deck four-legged jacket was established.The dynamic dynamic response state of the jecket under wave action was analyzed by using a nonlinear numerical model to obtain the structural dynamic response time course sample data,and then input into a composite neural network built by the Pytorch framework for training and testing after standardization processing.The calculation and analysis results show that the 1DCNN+GRU composite neural network prediction method has good solution accurate and stability, and each solution step length was less than the amount of forecast advance,which can achieve the dynamic dynamic response real-time prediction of offshore jacket platforms, and provie reference  for relevant engineering practices.
