      Tian, Xiaoqing; Wang, Zhenlin; Taalab, Elias; Zhang, Baofeng; Li, Xiaodong; Wang, Jiyong; Ong, Muk Chen; Zhu, Zefei (Peer reviewed; Journal article, 2022)
      With the growth of industrialization in recent years, the quality of drinking water has been a great concern due to increasing water pollution from industries and industrial farming. Many monitoring stations are constructed ...
    • Wave Influenced Wind and the Effect on Offshore Wind Turbine Performance 

      Kalvig, Siri M.; Manger, Eirik; Hjertager, Bjørn H; Jakobsen, Jasna Bogunovic (Journal article; Peer reviewed, 2014)
      In this paper the effect of wave influenced wind on offshore wind turbines is studied numerically. The wave is seen as a dynamical roughness that influences the wind flow and hence the wind turbine performance. An actuator ...
    • Welding procedure qualification record (WPQR) for welds fabricated at proximity 

      Bhardwaj, Sachin; RATNAYAKE MUDIYANSELAGE, Chandima (Peer reviewed; Journal article, 2022)
      Maintaining the minimum allowable distance between proximity welds has always been considered a subject of debate among design engineers, welding engineers/inspectors and fabricators/engineering contractors. The scattered ...
    • Wind coherence measurement by a single pulsed Doppler wind lidar 

      Kumer, Valerie-Marie; Cheynet, Etienne; Jakobsen, Jasna Bogunovic; Svardal, Benny; Reuder, Joachim (Journal article; Peer reviewed, 2016)
      A single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the along-wind component. To maximize the sampling frequency of the ...
    • Wind turbines designed for easy installation 

      Gudmestad, Ove Tobias (Peer reviewed; Journal article, 2020)
      The costs of installation, intervention/maintenance and decommissioning of fixed bottom, founded offshore wind turbine concepts are unreasonably high when using state of the art technology. For such wind turbine concepts, ...
    • Wind-induced response of an offshore wind turbine under non-neutral conditions: A comparison with Hywind Scotland 

      Putri, Rieska Mawarni; Obhrai, Charlotte (Peer reviewed; Journal article, 2022)
      In this study, aeroelastic simulations of a 5 MW spar wind turbine are performed by using simulated wind fields that are representative of surface layer marine atmospheric turbulence under different atmospheric stratifications. ...
    • Winterization and drilling operations in cold climate areas 

      Engtrø, Espen; Gudmestad, Ove Tobias (Peer reviewed; Journal article, 2019)
      Petroleum operations in remote locations offshore off northern Norway call for technical and operational solutions, sustainable and capable of withstanding extreme and harsh weather conditions. This paper discusses hazards, ...
    • Workflow and concept study to design mixed reality assisted safety training in the wind energy sector 

      Joghee, Sharath Chandar; El-Thalji, Idriss (Peer reviewed; Journal article, 2021)
      Mixed reality Technology creates new environments and visualizations to teach, train, and facilitate work, either offline or remote online. The aim is to provide effective learning and training sources and reduce human ...
