The beam mode of buckling of offshore pipelines is investigated. The pipeline was modeled as an elastoplastic, infinitely long beam, while the seabed was modeled as a fluid saturated, layered porous medium. The successive stiffness method, finite element method, and finite difference method were applied for the numerical study. Both beam vertical mode and beam lateral mode of buckling were studied. The results show that the buckling modes are influenced by the buried dearth, initial imperfection, and incline angle. The pipe tends to beam lateral mode of buckling for pipe with shallower buried depth, larger imperfection height, and smaller incline angle.
