“…Randolph et al [12] developed a standard set of parametric solutions based on an analytical model with a small drawback of discontinuity in the bending moment. Wang et al [13,14] improved the analytical model by guaranteeing the continuity of the bending moment, and also considered the variation in lateral soil resistance along the pipeline. Using these analytical models, a simple and fast solution of the pipeline behavior in landslides can be obtained [15].…”

“…With respect to the pipeline response assessment, Parker et al [12], Yuan et al [13,14], Yuan et al [15] and Ζhang et al [16] present both analytical and numerical models, that investigate the case of landslide impact vertical to the pipeline axis. The landslide impact is simulated as a linear drag force and pipe-soil interaction is modeled through bilinear elasticplastic springs.…”

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.

The deep‐sea ground contains a huge amount of energy and mineral resources, for example, oil, gas, and minerals. Various infrastructures such as floating structures, seabed structures, and foundations have been developed to exploit these resources. The seabed structures and foundations can be mainly classified into three types: subsea production structures, offshore pipelines, and anchors. This study reviewed the development, installation, and operation of these infrastructures, including their structures, design, installation, marine environment loads, and applications. On this basis, the research gaps and further research directions were explored through this literature review. First, different floating structures were briefly analyzed and reviewed to introduce the design requirements of the seabed structures and foundations. Second, the subsea production structures, including subsea manifolds and their foundations, were reviewed and discussed. Third, the basic characteristics and design methods of deep‐sea pipelines, including subsea pipelines and risers, were analyzed and reviewed. Finally, the installation and bearing capacity of deep‐sea subsea anchors and seabed trench influence on the anchor were reviewed. Through the review, it was found that marine environment conditions are the key inputs for any offshore structure design. The fabrication, installation, and operation of infrastructures should carefully consider the marine loads and geological conditions. Different structures have their own mechanical problems. The fatigue and stability of pipelines mainly depend on the soil‐structure interaction. Anchor selection should consider soil types and possible trench formation. These focuses and research gaps can provide a helpful guide on further research, installation, and operation of deep‐sea structures and foundations.
