Abstract Corrosive fatigue failure is universally existed in the submarine pipeline because of the immersion of pipeline in marine environment. An accurate method is critical for predicting the residual life of these pipelines. We studied the fatigue crack propagation behavior of the cracked pipeline under cyclic load of ocean waves, and proposed a novel approach for predicting the fatigue life of submarine pipeline. Then, we acquired the Paris law constants of X56 steel by employing the newly proposed shape factor to analyze the test data, and analyze the fatigue crack propagation behavior of the X56 steel under corrosive environment. Furthermore, we utilized the finite element software to simulate the fatigue crack propagation process and calculate the stress intensity factor (ΔK), and we conducted the residual life prediction of the X56 pipeline according to the Paris law. As could be seen from the results, for a given ΔK, the X56 steel pipeline showed a 1.6 times fatigue crack growth rates (da/dN) in seawater of that in air. Additionally, the influence of seawater on corrosive fatigue weakened gradually as the increasing fatigue crack growth rate. The results of residual life prediction of X56 steel pipeline conducted by the new approach was taken in comparison with the experimental results of a full-scale pipeline specimen, indicating the validity of the proposed approach in predicting the fatigue crack propagation state and the residual fatigue life of pipelines.
