    • 1st DeepWind 5 MW Baseline design 

      Paulsen, Uwe S.; Vita, Luca; Madsen, Helge A.; Hattel, Jesper; Ritchie, Ewen; Leban, Krisztina; Berthelsen, Petter Andreas; Carstensen, Stefan (Journal article; Peer reviewed, 2012)
      The first 5MW baseline design of the DeepWind concept is presented for a Darrieus type floating wind turbine system for water depths of more than 150 m. This design will be used as design reference to test the next ...

    • A metaheuristic solution method for optimizing vessel fleet size and mix for maintenance operations at offshore wind farms under uncertainty 

      Halvorsen-Weare, Elin Espeland; Norstad, Inge; Stålhane, Magnus; Nonås, Lars Magne (Journal article; Peer reviewed, 2017-10)
      Maintenance operations at offshore wind farms are challenging due to the offshore element; maintenance technicians and spare parts need to be transported from an onshore port or offshore station to the individual wind farm ...

    • Correlation between Acceleration and Drivetrain Load Effects for Monopile Offshore Wind Turbines 

      Rasekhi Nejad, Amir; Bachynski, Erin Elizabeth; Li, Lin; Moan, Torgeir (Journal article; Peer reviewed, 2016-09)
      This paper investigates the correlation between the tower-top axial acceleration and the load effects in drivetrain components in a monopile (bottom-fixed) offshore wind turbine. In designing offshore wind turbines, it is ...

    • DeepWind-from Idea to 5 MW Concept 

      Paulsen, Uwe S.; Madsen, Helge A.; Kragh, Knud A.; Nielsen, Per H.; Baran, I; Hattel, Jesper; Ritchie, Ewen; Leban, Krisztina; Svendsen, Harald Georg; Berthelsen, Petter Andreas (Journal article; Peer reviewed, 2014)
      The DeepWind concept has been described previously on challenges and potentials, this new offshore floating technology can offer to the wind industry [1]. The paper describes state of the art design improvements, new ...

    • OC5 Project Phase Ib: Validation of Hydrodynamic Loading on a Fixed, Flexible Cylinder for Offshore Wind Applications 

      Robertson, Amy N.; Wendt, Fabian; Jonkman, Jason M.; Popko, Wojciech; Borg, Michael; Bredmose, H.; Schlutter, Flemming; Qvist, Jacob; Bergua, Roger; Harries, Rob; Yde, Anders; Nygaard, Tor Anders; De Vaal, Jacobus Bernardus; Oggiano, Luca; Bozonnet, Pauline; Bouy, Ludovic; Barrera Sanchez, Carlos; Garcia, Raul Guanche; Bachynski, Erin Elizabeth; Tu, Ying; Bayati, Ilmas; Borisade, Friedemann; Shin, Hyunkyoung; van der Zee, Tjeerd; Guerinel, Matthieu (Journal article; Peer reviewed, 2016)
      This paper summarizes the findings from Phase Ib of the Offshore Code Comparison, Collaboration, Continued with Correlation (OC5) project. OC5 is a project run under the International Energy Agency (IEA) Wind Research Task ...

    • Optimizing Jack-up vessel strategies for maintaining offshore wind farms 

      Stålhane, Magnus; Christiansen, Marielle; Kirkeby, Odin; Mikkelsen, Andreas Jebsen (Journal article; Peer reviewed, 2017-10)
      In this paper we present a new two-stage stochastic mathematical programming model that determines the optimal jack-up vessel strategy for an offshore wind farm. Given an offshore wind farm site, and distance to shore the ...

    • Sensitivity Analysis of Limited Actuation for Real-time Hybrid Model Testing of 5MW Bottom-fixed Offshore Wind Turbine 

      Karimirad, Madjid; Bachynski, Erin Elizabeth (Journal article; Peer reviewed, 2017)
      The present paper studies the effect of limited actuation for real-time hybrid model testing (ReaTHM® testing) of a bottom-fixed offshore wind turbine in operational, parked, and fault conditions. ReaTHM® testing is a new ...

    • Vessel Fleet Optimization for Maintenance Operations at Offshore Wind Farms under Uncertainty 

      Stålhane, Magnus; Vefsnmo, Hanne; Halvorsen-Weare, Elin Espeland; Hvattum, Lars Magnus; Nonås, Lars Magne (Journal article; Peer reviewed, 2016-09)
      In this paper we consider the problem of determining the optimal fleet size and mix of vessels to support maintenance activities at offshore wind farms. A two-stage stochastic programming model is proposed where uncertainty ...
