Offshore single blade installation is a popular method for installing large offshore wind turbines. During an offshore operation, a jackup vessel is often used, and each blade is individually lifted by a crane and mated with the hub. This presentation will discuss the challenges of such an installation method including the environmental conditions, dynamic responses of the lifting and support structures, and human errors.  In addition, several measures are introduced for facilitating the single blade installation.  These measures include active tugger line control, tuned mass damper and specialized tools. The effects of these advanced measures are shown through numerical examples.



Dr. Zhiyu Jiang is a currently postdoctoral researcher at the department of Marine Technology, Norwegian University of Science and Technology (NTNU), Trondheim, Norway. He obtained his Bachelor and Master degrees from Shanghai Jiao Tong University in 2007 and 2010, respectively. He obtained his PhD degree at NTNU in 2008 with a topic on offshore wind turbine dynamics. From 2014 to 2016, he worked as a marine analysis engineer at NOV/APL.

Dr. Jiang’s research interests include offshore wind energy, marine operations, and design of marine structures. He has authored more than 30 peer-reviewed papers and serves as a reviewer for 11 international journals.
