  • Influence of Suspension Length on the Mechanical Response of Submarine Flexible Pipe under Internal Pressure and Transverse Load
    Advanced Materials Research, 2013
    Co-Authors: Hui Xin Wang, Dan Wang, Jia Quan Sun
    Abstract:

    According to the actual structure of submarine Flexible Pipe, considering the combined effect of internal pressure and transverse load by wave-current flow that is based on 50 year return period wave statistics data of Cheng Dao sea area, ANSYS finite element model of Flexible Pipe is established. The influence of internal pressure and suspension length on the axial stress of steel wire reinforcement layer and the Mises stress of rubber layer was analyzed. Comparatively, suspension is the main cause for the failure of steel submarine Pipeline, but could hardly lead to the failure of submarine Flexible Pipe, which shows that Flexible Pipe is stronger applicable for submarine Pipeline.

  • Study on Optimal Winding Angle of Submarine Oil Flexible Pipe
    Advanced Materials Research, 2012
    Co-Authors: Gan Song, Qiao Jin, Hui Xin Wang
    Abstract:

    According to the actual structure, using the finite element software ANSYS, numerical model of submarine oil Flexible Pipe was established. For the mechanical response of Flexible Pipe under the combined effect of internal pressure load and transverse load, the comparison on the result by numerical calculation and static loading test shows that the numerical model of Flexible Pipe is rational. Moreover, based on the numerical model of Flexible Pipe, this paper indicates that the maximum Mises stress occurs at the end of Flexible Pipe, which would lead to the bulge performance failure. Furthermore, the influence of winding angle on the mechanical properties of Flexible Pipe was analyzed, and the optimal winding angle 30° was suggested to adopt.

  • Study on the Influence of Transverse Load on the Mechanical Response of Submarine Flexible Pipe
    Applied Mechanics and Materials, 2012
    Co-Authors: Dan Wang, Hui Xin Wang, Jia Quan Sun
    Abstract:

    Taking 1 year return period wave data statistics of Cheng Dao sea area as an example, the wave-current flow hydrodynamic load acting on submarine Flexible Pipe was analyzed. According to the actual structure of submarine Flexible Pipe, ANSYS numerical model was established. Under the combined effect of internal operating pressure and transverse wave-current flow hydrodynamic load, the results calculated by numerical model shows that with the increase of transverse load, the bending deformation of Flexible Pipe increases linearly, and the stress of Flexible Pipe is almost constant.

  • Numerical Study on Mechanical Response of Steel Wire Wound Reinforced Rubber Flexible Pipe under Internal Pressure
    Advanced Materials Research, 2012
    Co-Authors: Hui Xin Wang, Li Sun
    Abstract:

    According to the actual structure of steel wire wound reinforced rubber Flexible Pipe, using the finite element software ANSYS, 3-D finite element model of Flexible Pipe is established. For the mechanical response of Flexible Pipe under internal pressure, the comparison on the result by numerical calculation, the static loading test and the result by analytic method shows that the 3-D finite element model of Flexible Pipe is rational. Moreover, based on the finite element model of Flexible Pipe, the influence of internal pressure, spanning length and reinforced steel wire diameter on the axial stress of the innerest steel layer and the Mises stress of the innerest rubber layer is analyzed.

  • Fatigue Analysis of Metallic Strips Flexible Pipe
    Volume 5: Pipelines Risers and Subsea Systems, 2018
    Co-Authors: Guowei Sun, Peihua Han, Yong Bai, Hamad Hameed
    Abstract:

    Metallic strips Flexible Pipe (MSFP) is widely regarded as an alternative for submarine Pipelines. This paper presents a methodology for calculating the fatigue life of MSFP. Firstly, given a specific working condition of MSFP, the dynamic responses of MSFP are calculated through OrcaFlex. The obtained results from the global analysis are then implemented into a finite element model in ABAQUS to determine the stress-history curves of each steel strips layer. The estimated fatigue life is calculated by rainflow counting algorithms, S-N curve and Miner’s rule which are coded in MATLAB. Additional study about average stress correction is carried out, which might be useful for its marine engineering applications.

  • Behavior of Flexible Pipe Subjected to Internal Pressure
    Volume 5: Pipelines Risers and Subsea Systems, 2016
    Co-Authors: Shuai Yuan, Wei Dong Ruan, Peihua Han, Yong Bai, Peng Cheng
    Abstract:

    The increasing use of Flexible Pipes in subsea with high pressure/high temperature brings about much more challenges. Although there has been a simple prediction method for burst pressure, a more comprehensive prediction of the ultimate strength of Flexible Pipe subjected to internal pressure is essential for the safe use of Flexible Pipe under complex environments in terms of different failure modes. In this paper, based on the principle of virtual work, a theoretical model for stresses and deformations of the Pipe under the short-term internal pressure have been developed and the obtained results have been compared with the ones from the FEM which is used to simulate the Pipe under increasing internal pressure using ABAQUS. And the mechanical properties of two kinds of armor layers have been studied comprehensively considering different boundary conditions. The results and FEA models can be useful for the design of Flexible Pipes. Finally, the failure prediction of a complete model is discussed.Copyright © 2016 by ASME
