Mooring line & anchor-seabed interaction for floating wind turbines
Offshore wind energy is abundant and has enormous potential in the future. At present, offshore wind energy development is mainly concentrated in very shallow areas, usually using fixed foundations such as monopiles or jackets. However, with the advancement of offshore wind energy towards deep and distant seas, floating wind turbines have more advantages. Floating wind turbines require a mooring system composed of mooring lines and anchors for positioning, so the safety of the mooring system is crucial for the floating wind turbines. This presentation focuses on the interaction between the mooring system and seabed, and explores related geotechnical engineering issues. The main content includes: (1) introduction to the floating wind turbine and its mooring system; (2) Mooring line-clay interaction and seabed trenching; (3) Mooring line-sand interaction; (4) influence of seabed trenches on suction anchor in sand; (5) Novel caisson-plate gravity anchor as shared anchor.
Short biography:
Shengjie Rui, Marie Curie Research Fellow. I am working at the Norwegian Geotechnical Institute (NGI) in Norway, engaged in research related to marine new energy development, offshore geotechnics, and ocean engineering. I led 1 European Union funding (MSCA Postdoctoral Fellowship 2022 with full marks) and published over 50 papers (including 45 peer-review papers). I served as a corresponding/nominated member of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) TC104 physical modelling, TC209 offshore geotechnics and TC213 scour and erosion. I was appointed as the Associate Editor of the SCI journal KSCE Journal of Civil Engineering. I was invited as Guest Editor in 'Frontiers in Marine Science', 'Sustainability' and 'Journal of Marine Science and Engineering' journal. In addition, I also served as a reviewer for more than 25 SCI journals, including Geotechnique, Acta Geotechnica, Journal of Geotechnical and Geoenvironmental Engineering, Engineering Geology, Computers and Geotechnics.
