Assessment of monopiles for lifetime extension of offshore wind turbines
Ziegler, Lisa (Doctoral theses at NTNU;2018:209, Doctoral thesis, 2018)Offshore wind is a fast-growing industry contributing to reduce CO2 emissions. Although most offshore wind turbines are still young today, we will face a significant fleet of ageing assets in the near future. The question ... -
Sensitivity of wave fatigue loads on offshore wind turbines under varying site conditions
Ziegler, Lisa; Voormeeren, Sven; Schafhirt, Sebastian; Muskulus, Michael (Journal article; Peer reviewed, 2015)Considerable variations in environmental site conditions can exist within large offshore wind farms leading to divergent fatigue loads on support structures. An efficient frequency-domain method to calculate wave-induced ...
