• Total experimental uncertainty in hydrodynamic testing of a semisubmersible wind turbine, considering numerical propagation of systematic uncertainty 

      Robertson, Amy N.; Bachynski, Erin Elizabeth; Gueydon, Sebastien; Wendt, Fabian; Schünemann, Paul (Journal article; Peer reviewed, 2020)
      Quantifying the uncertainty in experimental results is a critical step in properly validating numerical simulation tools for designing floating wind turbines; without a good understanding of the experimental uncertainties, ...
    • Validation of Hydrodynamic Loads on a Large-Diameter Monopile in Regular Waves 

      Hoseini Dadmarzi, Fatemeh; Thys, Maxime; Bachynski, Erin Elizabeth (Chapter, 2019)
      Validated hydrodynamic load models for large-diameter support structures are increasingly important as the industry moves towards larger offshore wind turbines. Experiments at 1:50 scale with stiff, vertical, bottom-fixed, ...
    • Validation of Numerical Wave Tank Simulations Using REEF3D With JONSWAP Spectra in Intermediate Water Depth 

      Pakozdi, Csaba; Fouques, Sebastien; Thys, Maxime; Kamath, Arun Mulky; Wang, Weizhi; Hoseini Dadmarzi, Fatemeh; Bachynski, Erin Elizabeth; Bihs, Hans Sebastian (;Paper No: OMAE2020-18298, V001T01A012, Chapter, 2020)
      As offshore wind turbines increase in size and output, the support structures are also growing. More sophisticated assessment of the hydrodynamic loads is needed, particularly for the ultimate limit state design. For ...
    • Verification of Numerical Offshore Wind Turbine Models Based on Full Scale Alpha Ventus Data within OC5 Phase III 

      Popko, Wojciech; Huhn, Matthias L.; Robertson, Amy N.; Jonkman, Jason M.; Wendt, Fabian; Müller, Kolja; Kretschmer, Matthias L.; Vorpahl, Fabian; Hagen, Torbjørn Ruud; Galinos, Christos; Dreff, Jean-Baptiste Le; Gilbert, Philippe; Auriac, Bertrand; Villora, Francisco Navarro; Schünemann, Paul; Bayati, Ilmas; Oh, Sho; Totsuka, Yoshitaka; Qvist, Jacob; Bachynski, Erin Elizabeth; Sørum, Stian Høegh; Thomassen, Paul Edgar; Shin, Hyun Kyoung; Vittori, Felipe; Galvan, Josean; Molins, Climent; Bonnet, Paul; Zee, Tjeerd van der; Bergua, Roger; Wang, Kai; Fu, Pengcheng; Cai, Jifeng (Chapter, 2018)
      The main objective of the Offshore Code Comparison Collaboration Continuation, with Correlation (OC5) project, is validation of aero-hydro-servo-elastic simulation tools for offshore wind turbines (OWTs) through comparison ...
    • Wave disturbance rejection for monopile offshore wind turbines 

      Smilden, Emil; Bachynski, Erin Elizabeth; Sørensen, Asgeir Johan; Amdahl, Jørgen (Journal article; Peer reviewed, 2019)
      The dimensions of offshore wind turbine (OWT) support structures are governed by fatigue considerations. For 6‐ to 10‐MW OWTs, wave loads are often dominating in terms of fatigue utilization. The present work proposes a ...
    • Wind-wave misalignment effects on floating wind turbines: motions and tower load effects 

      Bachynski, Erin Elizabeth; Kvittem, Marit Irene; Luan, Chenyu; Moan, Torgeir (Journal article; Peer reviewed, 2014)
      The dynamic responses of a spar, tension leg platform (TLP), and two semisubmersible floating wind turbines (FWTs) in selected misaligned wind and wave conditions are investigated using numerical simulation with an ...
