This study investigates the performance of multiple tuned mass-damper-inerter with electromagnetic motor (TMDI-EM) for dual objectives enhancing energy harvesting and dynamic in offshore wind turbines (OWTs). OWTs, inherently susceptible to sensitivity under lateral loads such as waves, necessitate effective solutions vibration mitigation while harnessing from excitations. The TMDI-EM configuration integrates an (EM) a shunt damper between secondary mass inerter element series. scalable inertance allows adaptability practical device implementations. Genetic Algorithm (GA) is employed find optimum parameters system. research focuses on response OWTs real-world conditions, where wave forces act correlated random Parametric analyses assess available at EM displacement variance OWT structure varies. employs methods optimize using Algorithm, ensuring system's optimal both enhanced response. findings indicate that lightweight TMDI-EMs, representing only 1.5 % structure's mass, demonstrate improved suppression increasing inertance. contributes into potential integration TMDI-EMs enhance capabilities dynamical loading conditions. use ensures identification system, its applicability.
