Aimed at the problem of excessive structural motion response caused by less constraints of weakly connected double floating body system in marine engineering,a multi-constrained offshore floating wind turbine coupled with hydrogen energy storage double floating structure is proposed based on the concept of"one machine,one storage"structure.The dynamic response characteristics of the multi-constrained double floating structure under general sea conditions are simulated and analyzed by Ansys software.The results show that:the wind-storage double floating structure coupled with hydrogen energy storage device is of small motion response in the three main degrees of freedom of surge,pitch and heave;the maximal heave motion amplitude of the hydrogen energy storage unit is only 7.21% of the height of the energy storage unit.The wind turbine coupled hydrogen energy storage double floating structure with multiple constraints under general sea conditions is of excellent motion performance.
