    • A comparison of extreme mooring loads and response of a spar-buoy wind turbine using conditional waves 

      Ripe, Aminda Marlen Titlestad; Lande-Sudall, David Roger (Peer reviewed; Journal article, 2023)
      Three-hour random sea-state evaluations for ultimate limit state design of floating offshore wind installations are time-consuming and prevent the use of high-fidelity numerical methods from being implemented. In this work, ...

    • Experiments on the wake flow behind different configurations of multirotor wind turbines 

      Jørs, Andreas; Mjåtveit, Torbjørn; Skoland, Morten; Stenfelt, Gloria Maria; Hansen, Thomas Henrik Hertzfelder; Bartl, Jan Michael Simon (Peer reviewed; Journal article, 2023)
      Multirotor wind turbine concepts have recently emerged as a promising alternative to conventional turbines. When arranged in farms, the wake flow behind multirotor assemblies becomes an important factor in the cost-of-energy ...

    • Experiments on upstream induction and wake flow for multirotor wind turbines 

      Stenfelt, Gloria Maria; Hansen, Thomas Henrik Hertzfelder; Skoland, Morten; Koi, Idunn (Peer reviewed; Journal article, 2023)
      Multirotor wind turbine concepts are increasingly discussed as cost-effective alternatives for floating wind energy installations. When multiple smaller rotors are installed next to each other, the individual rotors ...

    • Lab-scale measurements of wind farm blockage effects 

      Bartl, Jan Michael Simon; Aasnæs, Camilla Hamre; Bjørnsen, Joakim Rinke; Stenfelt, Gloria; Lande-Sudall, David Roger (Peer reviewed; Journal article, 2022)
      The inflow an individual wind turbine experiences in a farm layout is strongly dependent on flow interaction effects with the turbines surrounding it. In addition to the well-known wake flows, lateral and upstream flow ...

    • Layout and yaw optimisation of an offshore wind farm through analytical modelling 

      Sukhman, Daniel; Lück, S.; Göing, J.; Bartl, Jan Michael Simon; Hansen, Thomas Henrik Hertzfelder; Stenfelt, Gloria Maria; Friedrichs, J. (Peer reviewed; Journal article, 2023)
      In this work, a computational tool for analytical large scale modelling of offshore wind farms is presented. Using Horns Rev 1 as a reference baseline, an optimal layout and yaw angle setting for one wind direction based ...

    • Wave-induced collision loads and moments between a spar-buoy floating wind turbine and an installation vessel 

      Lande-Sudall, David; Høyven, Thomas Skinlo; Herfjord, Kjell Agnar; Thuestad, Thore Clifford (Journal article; Peer reviewed, 2020)
      Spar-buoy floating wind turbines (FWTs) have been deployed at full-scale off the coast of Scotland. However, their deep draught restricts their wider-suitability for assembly and installation at shallow water ports. Here ...
