This paper summarizes the analysis methods and related seismic design codes for pipeline crossing earthquake fault. By analyzing the differences between submarine pipelines and onshore pipelines in the fault crossing analysis, the paper proposes the recommended method of submarine pipeline crossing earthquake fault analysis. Relying on the project case, the finite element method is used to analyze the response of the submarine pipeline under the action of earthquake fault. The design optimization is also given.
