“…It might be due to the adjustment of stresses in the pipeline with a variation of pressure and thickness. It can be concluded that if the pipeline were subjected to a pressure between 150 kPa and 250 kPa at a small exposed length, the shear failure would happen, and the same failure mechanism was reported in similar studies in the literature [19,37].…”

“…Furthermore, previously published literature [24][25][26] and many oil and gas companies such as Transredes oil and gas pipeline, Bolivia [22] Pacific northern gas pipeline in British Columbia, Canada [27], and most recently Sabah and Sarawak gas pipeline, Malaysia [28] conducted an in-depth investigation in the failure of pipelines. The latter suggested a detailed investigation of pipeline failure due to the impact of debris flow by considering the relevant parameters of wall thickness and impact angle.…”

This article examines the impact of debris flow on semi-exposed pipelines to determine the plastic deformation and stresses by considering pipe-debris flow interaction. A 3-D finite element approach was adopted to study the mechanical behavior of pipelines subjected to debris flow. Integration of pipeline property (thickness) with debris flow intensity (impact pressure and angle) was also considered in a finite element numerical model for semi-exposed. The analysis showed that the impact angle between 35° and 75° with an impact pressure of 200 kPa and 250 kPa significantly affected the stability and integrity of the pipeline. There was a slight impact of wall thickness on the stability of the pipeline due to the passive soil resistance. Maximum plastic deformation of 124 mm was encountered in the case of 35° impact angle, which was 3% more than the deformation observed at 20° impact angle. Moreover, large distribution of von mises stresses was observed, as 1390 Mpa, 1450 Mpa, 1440 Mpa, and 1440 Mpa for impact angles of 20°, 35°, 75°, and 90° in the impacted zone of the pipeline in each set of analysis. Shear failure of the pipeline was observed during the analysis as von misses’ stresses were more than the yield stress (520 Mpa) of the pipeline. The developed model in this study can be utilized for further research and will be a basis for designing pipelines crossing through mountainous regions.

“…Ismail et al [7] used FEM to evaluate the influence of pipeline's diameter, buried depth, wall thickness and other parameters on the resistance to upheaval buckling of buried submarine pipeline. Zhang et al [33] analyzed the pipeline's deformation caused by radial impact, inclined impact, and eccentric impact of spherical rockfall and cubic rockfall. The results indicated that the smaller the curvature radius of the rockfall contact area is, the greater the damage to the pipeline will be.…”

Load impact, such as the rockfall, may bring significant threats to the integrity management of pipeline. This study is intended to evaluate the reliability of buried pipeline under rockfall impact, and so as to reduce the possible failure and unnecessary downtime. Firstly, the dynamic response of the buried pipeline under load is analyzed by Euler Bernoulli foundation beam. After that, the process of rockfall impact on buried corroded pipeline is simulated with nonlinear finite element method. Furthermore, the influence of rockfall’s parameters (including rockfall mass, impact velocity, impact position, etc.) on the pipeline’s equivalent stress is quantitatively analyzed. Eventually, a time-varying reliability model is established to calculate the failure probability. The results indicate that the mass and velocity of the rockfall have obvious influence on the pipeline’s failure probability, and the change of impact’s position has small influence. The proposed method can provide a theoretical reference for the design and maintenance of buried pipeline.
