In this paper, the reference stress method is adopted in the residual strength assessment of corroded subsea pipeline. Through the monitoring of the von Mises stress σlocal in the minimum cross section, the relationship between the stress response and input pressure is found. Then, based on this relationship, a simple and effective method to assess the residual strength of corroded subsea pipeline is proposed. Through the comparison with experimental results, the accuracy and reliability of this method is confirmed.
