Methodological basis used for the simulation campaign described here.
Research / Dynamic response
Dynamic Response Explorer
Explore the simulated tower-top response of a jacket-supported offshore wind turbine under uncontrolled and actively controlled conditions.
The interface presents a selected post-transient interval from a numerical simulation and allows direct comparison of horizontal structural response.
