Offshore Natural Gas Pipelines Subjected to Kinematic Distress

Abstract

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.
