The paper presents a simplified reliability analysis method, which specifically calculates the Probability of Non-Formations or Formations (PoNF or PoF) for planned or rogue buckles along pipeline routes laid on undulating seabed. Formulation is developed to calculate the probability of formation by comparing the critical buckling force against the effective axial forces. The approach's unique and important feature is it facilitates an input deck to directly accept seabed bathymetrical data, convert it to an out-of-straightness parameter and thus calculate its influence of the seabed out-of-straightness on the formation of planned and rogue buckles. The method is considered a viable tool to aid the design of long-length on-bottom pipelines requiring both buckling and walking mitigation.
