    • Code-to-Code Verification of End-Anchored Floating Bridge Global Analysis 

      Viuff, Thomas; Xiang, Xu; Leira, Bernt Johan; Øiseth, Ole (Chapter, 2018)
      A code-to-code comparison of the dynamic characteristics of an end-anchored floating pontoon bridge is presented for two commercial software commonly used in the offshore industry, i.e. SIMO-RIFLEX and ORCAFLEX. Furthermore, ...

    • Dynamic Response of a Floating Bridge Structure 

      Viuff, Thomas; Leira, Bernt Johan; Øiseth, Ole; Xiang, Xu (Chapter; Peer reviewed, 2016)
      A theoretical overview of the stochastic dynamic analysis of a floating bridge structure is presented. Emphasis is on the wave-induced response and the waves on the sea surface are idealized as a zero mean stationary ...

    • Effect of Damping on the Dynamic Responses of a Floating Bridge in Wind and Waves 

      Hong, Sunghun; Cheng, Zhengshun; Gao, Zhen; Shao, Yanlin; Xiang, Xu (Chapter, 2020)
      The E39 Coastal Highway Route Project is being developed to reduce the travel time between Trondheim and Kristiansand in Norway and several ferry connections are planned to be replaced by floating bridges or submerged ...

    • Effects of wave directionality on extreme response for a long end-anchored floating bridge 

      Viuff, Thomas; Leira, Bernt Johan; Xiang, Xu; Øiseth, Ole (Journal article; Peer reviewed, 2019)
      Reliable design codes are of great importance when constructing new civil engineering concepts such as floating bridges. Previously only a scarce number of floating bridges have been built in rough wave conditions and ...

    • Extensive hydro-elastic floating bridge tests: Planning, design, implementation, and numerical comparison 

      Xiang, Xu (Peer reviewed; Journal article, 2023)
      Extensive hydrodynamic and hydro-elastic tests for a long floating bridge have been carried out in the ocean basin of SINTEF Ocean for the Bjørnafjord floating bridge project. The complexity of the floating bridge plus ...

    • Hydrodynamic interaction of floating bridge pontoons and its effect on the bridge dynamic responses 

      Fenerci, Aksel; Kvåle, Knut Andreas; Xiang, Xu; Øiseth, Ole Andre (Peer reviewed; Journal article, 2022)
      As pontoons of floating bridges respond to the dynamic actions of the wind and wave loading, additional forces are imposed on the pontoons due to the hydrodynamic interaction of these floating bodies. The wave forces on a ...

    • Impact of Hydrodynamic Interaction Between Pontoons on Global Responses of a Long Floating Bridge Under Wind Waves 

      Xiang, Xu; Viuff, Thomas; Leira, Bernt Johan; Øiseth, Ole (Chapter, 2018)
      The hydrodynamic interaction between floating bridge pontoons and its impact on the bridge global responses are investigated in the current study. The global model for end-anchored floating bridge for Bjørnefjord crossing ...

    • Maneuvering of two Interacting Ships in Calm Water 

      Xiang, Xu; Faltinsen, Odd (Chapter, 2010)
      The maneuvering of two interacting ships in calm water at Froude numbers less than ~0.2 and in water of infinite horizontal extent is studied based on an extended version of the maneuvering model for two ships by Skejic ...

    • Maneuvering of two interacting ships in waves 

      Xiang, Xu (Doktoravhandlinger ved NTNU, 1503-8181; 2012:361, Doctoral thesis, 2012)
      This thesis describes the development of a module based maneuvering prediction system for one ship or two interacting ships in calm water or waves. The work is a continuation and generalization of the previous work of ...

    • Model uncertainty assessment for wave- and current-induced global response of a curved floating pontoon bridge 

      Viuff, Thomas Hansen; Xiang, Xu; Øiseth, Ole Andre; Leira, Bernt Johan (Peer reviewed; Journal article, 2020)
      The present paper provides a comparison between the numerical and experimental response for a generic floating pontoon bridge structure, thereby also serving to quantify the inherent uncertainties associated with both types ...

    • Modelling and Analysis of a Floating Bridge 

      Vika, Eirik Breisnes (Master thesis, 2018)
      The Norwegian National Public Road Administration is working on a project to improve the coastal road E39, connecting the cities along the west coast of Norway. Today, this road has seven ferry crossings which are to be ...

    • Numerical studies of viscous flow around straight and curved tandem cylinders 

      Aasland, Tale Egeberg (Doctoral theses at NTNU;2024:81, Doctoral thesis, 2024)
      The physics of flow around straight and curved cylinders in tandem is investigated by means of direct numerical simulations (DNS), for transitional and turbulent flow regimes. For straight tandem cylinders in the reattachment ...
