      The present paper consolidates available experimental results for both sub-critical and critical Reynolds numbers and varying surface roughness and formulates a coefficient excitation model that aims at unbiased response ...
    • Dominant parameters for vortex-induced vibration of a steel catenary riser under vessel motion 

      Wang, Jungao; Fu, Shixiao; Larsen, Carl Martin; Baarholm, Rolf; Wu, Jie; Lie, Halvor (Journal article; Peer reviewed, 2017)
      Recent research has confirmed a new type of vortex-induced vibration (VIV) in steel catenary risers (SCRs), purely caused by vessel motion. Vessel motion-induced VIV occurs because the SCR is exposed to the equivalent ...
    • Forced Vibration Tests for In-Line VIV to Assess Partially Strake-Covered Pipeline Spans 

      Wu, Jie; Yin, Decao; Passano, Elisabeth; Lie, Halvor; Peek, Ralf; Sequeiros, Octavio E.; Ang, Sze; Bernardo, Chiara; Atienza, Meliza (ASME Digital Collection;OMAE2019-95970, Chapter, 2019-06)
      A series of experiments is performed in which a strake-covered rigid cylinder undergoes harmonic purely in-line motion while subject to a uniform “flow” created by towing the test rig along SINTEF Ocean’s towing tank. These ...
    • Hydrodynamic Coefficients of a Flexible Pipe With Staggered Buoyancy Elements and Strakes under VIV Conditions 

      Fu, Shixiao; Lie, Halvor; Wu, Jie; Baarholm, Rolf Jarle (ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-62535, Chapter, 2017-06-25)
      A 38m long flexible pipe with staggered buoyancy modules and strakes has been tested in the ocean basin of SINTEF Ocean (former Marintek) for VIV investigation of a lazy wave riser. In this paper the inverse analysis method ...
    • Hydrodynamics of Flexible Pipe With Staggered Buoyancy Elements Undergoing Vortex-Induced Vibrations 

      Zhang, Mengmeng; Fu, Shixiao; Song, Laijian; Wu, Jie; Lie, Halvor; Ren, Haojie (ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61265, Chapter, 2017-06-25)
      Flexible riser with staggered buoyancy elements has been widely used in ocean engineering, such as steel lazy wave riser, drilling riser, etc. Both the buoyancy elements and the riser may experience vortex induced vibrations ...
    • In-Line VIV Based on Forced-Vibration Tests 

      Yin, Decao; Wu, Jie; Passano, Elisabeth; Lie, Halvor; Peek, Ralf; Sequeiros, Octavio E.; Ang, Sze; Bernardo, Chiara; Atienza, Meliza (ASME Digital collection;OMAE2019-95972, Chapter, 2019-06-14)
      Excitation and added mass functions determined from forced vibration tests of a rigid cylinder undergoing harmonic motion in the flow are used in the semi-empirical software VIVANA to predict the VIV response of pipelines. ...
    • OMAE2017-61768 VIV Responses of Riser With Buoyancy Elements: Forced Motion Test and Numerical Prediction 

      Wu, Jie; Lie, Halvor; Fu, Shixiao; Baarholm, Rolf Jarle; Constantinides, Yiannis (ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61768, Chapter, 2017-06-25)
      Steel Lazy Wave Riser (SLWR) is an attractive deep water riser concept. When subjected to vortex induced vibrations (VIV), the vortex shedding process of the buoyancy element and the bare riser section will be different ...
    • On the significance of the higher-order stress in riser vortex-induced vibrations responses 

      Wu, Jie; Yin, Decao; Lie, Halvor; Larsen, Carl Martin; Baarholm, Rolf Jarle; Liapis, Stergios (Journal article; Peer reviewed, 2019-02)
      Vortex-induced vibrations (VIV) can lead to fast accumulation of fatigue damage and increased drag loads for slender marine structures. VIV responses mainly occur at the vortex shedding frequency, while higher harmonics ...
    • Prediction of Combined IL and CF VIV Response of Deepwater Risers 

      Wu, Jie; Lekkala, Malakonda Reddy; Ong, Muk Chen; Passano, Elisabeth; Voie, Per Erlend (ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61766, Chapter, 2017-06-25)
      Deepwater risers are susceptible to Vortex Induced Vibrations (VIV) when subjected to currents. When responding at high modes, fatigue damage the in in-line (IL) direction may become equally important as the cross-flow ...
