Abstract
This thesis introduces a novel contactless method for controlling the motion of suspended components during offshore wind turbine installations. Conventional systems rely on mechanical contact and are susceptible to wave-induced disturbances. The proposed technique exploits magnet-to-magnet interactions between mounted permanent magnets and external electromagnetic actuators to achieve non-contact attenuation of both translational and rotational vibrations. The proof-of-concept design of this method is validated through numerical simulations and scaled laboratory experiments. Results demonstrate effective motion mitigation and precise positioning under dynamic conditions. This investigation highlights the potential of magnetic control to enhance safety, accuracy, and efficiency in challenging offshore environments, offering a promising alternative to traditional motion compensation systems.
