Abstract The buried pipeline subjected to strike-slip fault would experience large deformation and cause tensile rupture or shear failure of the pipe wall. In order to investigate the mechanism of potential failure position (PFP) of a pipeline, a numerical approach based on the Vector Form Intrinsic Finite Element (VFIFE) method with fiber beam element model (VFIFE-fiber model) is developed. Several key factors, such as geometrical nonlinearity, material nonlinearity, and the interaction between axial force and bending moment are considered. A simple and practicable formula for obtaining the PFP of a pipeline is proposed. © Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).
