Randomized trial evaluates mooring line actuation's impact on stabilization of floating offshore wind turbines, suggesting innovative control strategies.
Key Points
This research aims to explore the effectiveness of mooring line actuation in stabilizing floating offshore wind turbines under dynamic conditions.
Two platform configurations are modeled: a spar-buoy and a tension-leg platform (TLP).
A tuned mass damper (TMD) strategy is used as a benchmark for comparative evaluation.
A Linear Quadratic Regulator (LQR) controller is designed to modulate mooring line lengths and tensions.
Mooring line actuation (MLA) significantly enhances stabilization for the TLP configuration compared to the spar-buoy.
The proposed MLA strategy effectively suppresses simultaneous surge and pitch with minimal actuation.
Improvements in MLA performance are noted in platforms with lower inherent controllability.
