Abstract In this work, a National Renewable Energy Laboratory (NREL) 5.0 MW floating offshore wind turbine (FOWT) model equipped with nonlinear, magnetorheological (MR) tuned vibration absorber (TVA) is analysed. Several optimal-based MR damper control solutions are regarded against passive TVA configurations and the structure without the TVA system. Tower and barge/platform angular displacement amplitude frequency responses are compared, proving the efficiency and robustness of the adopted vibration reduction solutions, as well as their capability to minimise the amplitude of the vibrating structure, the demanded actuator (e.g. MR damper) force and stroke range.
