Abstract:The force acting on the floating pipeline on the sea was analyzed,an analysis model of the floating pipeline on the sea was introduced. ADINA software was used to analyze the deformation of the DN100 field pipeline with the method of fluid-structure interaction. The deformation of the pipeline was researched in comparison with the theoretical value, and the model is proved to be feasible.
Key words: floating pipeline on sea; internal flow changes; fluid-structure interaction; deformation |
