Abstract
This study aims at providing a model prediction technique for the fatigue life of offshore steel risers using a hybrid of finite element analysis and the artificial neural network (FEA-ANN) model. A 200 days’ environmental load from Forcados sea state in West Africa offshore was used in training the FEA-ANN model to predict fatigue. The prediction result showed that the mean square error (MSE) was 0.3329 and the analysis from the regression was 0.9999. The result from the training showed a high performance and the regression analysis of the model was seen to be good.
