Proc. ASME. IOWTC2019, ASME 2019 2nd International Offshore Wind Technical Conference, V001T01A040, November 3–6, 2019
Paper No: IOWTC2019-7541
... Abstract In aero-elastic simulation of offshore wind turbines, the support structure can be modelled using an “integrated” approach, where the jacket and tower and modelled explicitly as one structural body, or a “superelement” approach, where the jacket part of the support structure...

Proc. ASME. OMAE2019, Volume 10: Ocean Renewable Energy, V010T09A073, June 9–14, 2019
Paper No: OMAE2019-96168
... Abstract Due to the complex nature of the loads on Offshore Wind Turbines (OWTs), accurate and optimized design of these structures require integrated simulation tools that can properly capture the various structural interactions governing the response. Considerable progress has been made...
