Abstract: Upheaval buckling (UHB) is a common design issue for buried pipelines when the out-of-straightness of the pipeline combined with the high axial compressive forces induced by the extreme operating conditions causes the ...

Abstract: Offshore pipelines are commonly buried in seabeds for protection against damage, for better insulation, and to prevent upheaval buckling induced by thermal and pressure loadings. The seabed imperfection is one of the ...

Abstract: Offshore oil and gas pipelines are commonly buried in seabed to provide environmental stability, thermal insulation and mechanical protection. These pipelines are frequently subjected to high thermal and pressure loadings ...

Abstract: It is common in practice to utilize finite elements for obtaining a solution for soil–structure interaction problems. There are different finite-element methods (such as implicit and explicit) being employed at present to ...

Abstract: This study investigates the interaction between soil and pipeline in sand subjected to lateral ground displacements with emphasis on the peak force exerted to a bended elbow-pipe. A series of three-dimensional (3D) ...

Abstract: The initial embedment of as-laid offshore pipeline is one of the important design considerations for on-bottom stability analysis. Despite the significant advancement in the use of numerical and analytical methods to predict ...

Abstract: Because pipelines traverse large geographical areas, they frequently must cross active faults when constructed in locations vulnerable to earthquakes. In this study, the authors performed three-dimensional (3D) finite-element ...
