The development trends of free spanning evaluation and related criteria in the pipeline industry from the 1980s are presented. An example is given to calculate the maximum allowable span length by different codes. Then, the differences in the criteria and critical cases are compared and the reasons for these differences are analyzed. Finally, based on the engineering experience and the in-service evaluation results, suggestions on the code selection for submarine pipeline design and in-service evaluation are given.
