    • A Time-Domain Method for Hydroelastic Analysis of Floating Bridges in Inhomogeneous Waves 

      Fu, Shixiao; Wei, Wei; Ou, Shaowu; Moan, Torgeir; Deng, Shi; Lie, Halvor (Chapter; Peer reviewed, 2017)
      Based on the three dimensional potential theory and finite element method (FEM), this paper presented a method for time-domain hydroelastic analysis of a floating bridge in inhomogeneous waves. A floating bridge in both ...

    • Analysis of full-scale riser responses in field conditions based on Gaussian mixture model 

      Wu, Jie; Eidnes, Sølve; Jin, Jingzhe; Lie, Halvor; Yin, Decao; Passano, Elizabeth Anne; Sævik, Svein; Riemer-Sørensen, Signe (Peer reviewed; Journal article, 2022)
      Offshore slender marine structures experience complex and combined load conditions from waves, current and vessel motions that may result in both wave frequency and vortex shedding response patterns. Field measurements ...

    • Data-Driven Prediction of Vortex-Induced Vibration Response of Marine Risers Subjected to Three-Dimensional Current 

      Riemer-Sørensen, Signe; Wu, Jie; Lie, Halvor; Sævik, Svein; Kim, Sangwoo (Chapter, 2019)
      Slender marine structures such as deep-water marine risers are subjected to currents and will normally experience Vortex Induced Vibrations (VIV), which can cause fast accumulation of fatigue damage. The ocean current is ...

    • 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 ...

    • Estimation of VIV-parameters based on Response Measurements and Bayesian Machine Learning Algorithms 

      Andersen, Martin Lieberkind; Sævik, Svein; Leira, Bernt Johan; Wu, Jie; Langseth, Helge; Passano, Elizabeth Anne; Lie, Halvor; Yin, Decao (Chapter, 2022)
      Analysis of structural response levels due to hydro-elastic vortex-induced vibrations (VIV) involves the specification of several parameters both associated with the fluid flow and the structural properties. To the maximum ...

    • Hydrodynamic modelling and estimating response of a glacial ice near a drilling rig 

      Ommani, Babak; Berthelsen, Petter Andreas; Lie, Halvor; Aksnes, Vegard Øgård; Løland, Geir (Chapter, 2019)
      Impact scenarios involving a typical drilling rig and glacial ice are studied. The goal is to better identify the important physical effects in modelling the dynamics of glacial ice in presence of waves and a floating ...

    • Improved VIV Response Prediction Using Adaptive Parameters and Data Clustering 

      Wu, Jie; Yin, Decao; Lie, Halvor; Riemer-Sørensen, Signe; Sævik, Svein; Triantafyllou, Michael (Peer reviewed; Journal article, 2020)
      Slender marine structures such as deep-water riser systems are continuously exposed to currents, leading to vortex-induced vibrations (VIV) of the structure. This may result in amplified drag loads and fast accumulation ...

    • 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)
      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 ...

    • State-of-the-Art Review of Vortex-Induced Motions of Floating Offshore Wind Turbine Structures 

      Yin, Decao; Passano, Elisabeth; Jiang, Fengjian; Lie, Halvor; Wu, Jie; Ye, Naiquan; Sævik, Svein; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)
      The motivation for this study is the fast development of floating offshore wind energy and the immature methodology and engineering practice related to predictions of vortex-induced motions (VIM). Benefiting from the oil ...

    • Time Domain VIV Analysis Tool VIVANA-TD: Validations and Improvements 

      Wu, Jie; Jin, Jingzhe; Yin, Decao; Lie, Halvor; Passano, Elisabeth; Sævik, Svein; Tognarelli, Michael; Grytøyr, Guttorm; Andersen, Torgrim; Karunakaran, Daniel; Igland, Ragnar Torvanger (Chapter, 2020)
      An empirical time-domain (TD) vortex-induced vibration (VIV) prediction model has been implemented in a software called VIVANA-TD based on its earlier development by Thorsen at NTNU. It models the synchronization of VIV ...
