<p>Flexible pipes are compounded by many concentric layers, with different structural and operational functions. These layers are usually made of distinct materials, including metal and plastic. To accurately meet the working requirements of the pipes and reduce its production cost, the primary purpose of this paper is to present the cross-sectional design procedure and the case study for a specific unbonded flexible pipe is also illustrated.In this paper, the mathematical analysis and finite element analysis are employed to study the properties of pipe under different working conditions. A theoretical model for stresses and deformations of the pipe have been studied, and the obtained results have been compared with the ones from the FEM which is usedtosimulate thepipeunderdifferentworking conditions. Additionally, the several models will be developed to study mechanical responses of pipes subjected to several loads. The results and FEA models can be useful for the designing structure of flexible pipes.The increasingly employment of unbonded flexible pipe in the oil/gas industry has brought significant challenges in the design process. The design of flexible pipe includes cross-sectional design and accessories design. The primary purpose of this paper is to present the cross-sectional design procedure and the case study for a specific unbonded flexible pipe is also illustrated. It is widely recognized that the special construction of layers contributes to the extensively application of unbonded flexible pipe in the deepwater.&nbsp;</p>

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
