“…where H is the pipeline depth, D is the pipeline diameter, and A, B, and C are fitting parameters determined by the undrained shear strength of the soil. e values of A, B, and C were those used in [31], i.e., 0.756, 0.461, and 0.204, respectively. Separation and slippage usually occur between pipe and gasket.…”

Frequent accidents caused by underground pipeline damage are a widespread societal concern. Trenchless rehabilitation methods, particularly cured-in-place pipe (CIPP) lining, are increasingly used for pipeline repair with great success. Existing research is mainly concerned with practical improvements in rehabilitation and evaluating the performance of rehabilitation. In this study, the model of corroded buried concrete pipeline that had been rehabilitated with CIPP was established using numerical methods, and the Mesh-based parallel-Code Coupling Interface (MpCCI) was used to investigate multifield coupling effects of soil pressure, traffic load, and fluid-structure interactions. Moreover, the influences of corrosion depth, corrosion width, traffic load, cover depth, and water quantity on CIPP wall thickness were compared and analyzed. The result shows that maximum principal stress and vertical displacement of pipeline markedly decreased after CIPP rehabilitation, and thus the new CIPP can carry loads in a deteriorated pipe. Stress and displacement of the composite pipe liner were positively correlated with corrosion depth and negatively correlated with corrosion width. Increase in traffic load rapidly increases von Mises stress of CIPP, and increase in cover depth rapidly increases maximum principal stress of pipeline. Water flow has little effect on the pipe liner, and flow capacity increases slightly after CIPP rehabilitation. CIPP wall thickness was positively correlated with corrosion depth, traffic load, cover depth, and water quantity and negatively correlated with corrosion width.

“…For the pipeline having diameter of 406.4mm and wall thickness of 14.5 mm the allowable stress range is 261.66 MPa. [22][23][24][25][26] The allowable stress for the pipeline is 255.6 MPa. 14 The result obtained does not exceed the allowable level but we still have 2.3% to reach the allowable stress level.…”

Designed loads on the sea buried pipeline include internal pressure of the product (natural gas), temperature of the transported product, and weight load of the medium. Certain operating conditions may lead to strength-threatening tension in the subsea pipeline, which is instantaneous us under static and dynamic random exposures. Load analysis of the main combination is shown in Figure 1 (note: sea buried pipeline is an object of the analysis). The purpose of this study is to evaluate damages of the natural gas pipelines due to fatigue caused by cyclic fluctuations of transportation temperature which contribute to defect growth.

Abstract. Hydrocarbons are undoubtedly the main energy source of the twenty-first century. Over the last decades the increase in energy needsFor this purpose, the aim of this work is to study numerically, utilizing the finite element method, the kinematic distress ) of an offshore natural gas pipeline due to a submarine landslide. Firstly, the developed numerical models are validated using available analytical solutions, and subsequently various parameters that affect the examined problem are investigated. The detailed parametric analysis covers among others, the impacted force on the pipeline, the landslide length, internal pressure levels, slope inclinations and diameter to thickness ratios.
