      Voie, Per Erlend; Wu, Jie; Resvanis, Themistocles; Larsen, Carl Martin; Vandiver, Kim; Triantafyllou, Michael S.; Baarholm, Rolf Jarle (ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61362, Chapter, 2017-06-25)
      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 ...
    • 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 ...
    • 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 Design Considerations of New Offloading Hose Applied on a Turret Moored FPSO 

      Yin, Decao; Fylling, Ivar John; Lie, Halvor; Baarholm, Rolf Jarle; Kendon, Timothy Edward (ASME Digital collection;OMAE2017-61410, Chapter, 2017-06)
      Offloading hoses are used to transfer crude oil or liquid petroleum products from a fixed offshore production platform/floating production, storage and offloading (FPSO) unit to shuttle tankers. The hoses are subjected to ...
    • 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 ...
    • Prototype Reynolds Number VIV Tests on a Full-scale Rigid Riser 

      Yin, Decao; Lie, Halvor; Baarholm, Rolf Jarle (J. Offshore Mech. Arct. Eng;OMAE-17-1069, Journal article; Peer reviewed, 2017-09)
      Slender offshore structures in deep water subjected to currents may experience vortex-induced vibrations (VIV), which can cause significant fatigue damage. Extensive experimental researches have been conducted to study the ...
