Wind Turbine Towers: Day 1 - 27/08/2025

8:30 - 9:00 Registration and Welcome Coffee

9:00 - 9:10 Opening Remarks

9:10 - 9:40 Opening Keynote: Opportunities and Challenges of Next- Generation Towers >200 m, >10 MW

-Structural and logistical constraints beyond current standards

-New turbine generations and the pressure on tower design

-The balancing act between height, cost, and manufacturability

9:40 - 10:10 Structural challenges in internals of larger and more flexible towers

-With increasing turbine sizes, tower diameters and heights have increased significantly in the recent years.

-Larger towers lead to larger deformations and to different vibrational behaviour, impacting the tower internals

-New failure modes in tower internals have been observed in the field and ask thus for changes in the design methods for these, up to now often overlooked, components.

-This presentation will provide an overview on these new challenges and propose approaches for improved structural design of tower internals.
