A comparative fatigue reliability study for key structural components of offshore wind turbines
Dong, Wenbin; Li, Qinyuan; Gao, Zhen; Moan, Torgeir (Chapter, 2018)In this paper, the fatigue reliability of blade root and tower base of a jacket wind turbine, the OC4 semi-submersible wind turbine and a land-based wind turbine is investigated and compared. The fatigue reliability of ... -
Damage identification of a jacket support structure for offshore wind turbines
Jiang, Zhiyu; Bjørnholm, Marius; Guo, Jiamin; Dong, Wenbin; Ren, Zhengru; Verma, Amrit Shankar (Chapter, 2020)Offshore jacket structures are regarded as a suitable type of support structure for offshore wind turbines in immediate water depths. Because of the welded tubular members used and environmental conditions, offshore jackets ... -
