... 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...

... Abstract Traditionally, the design of submarine pipeline routes has been performed manually, by inspection of the seabed bathymetry and obstacles (platforms, equipment, other pipes, etc.). However, this traditional approach has some problems; it is highly dependent on the experience...
