Fabricated ductile defense jacket offshore wind turbine and manufacturing method thereof

The invention discloses an assembly type toughness defense jacket offshore wind turbine and a manufacturing method thereof. The assembly type toughness defense jacket offshore wind turbine comprises a jacket foundation, a tower drum and a wind turbine body. The tower drum is arranged at the top of the jacket foundation, and the fan is mounted at the top of the tower drum through a base; the jacket foundation comprises a plurality of guide pipe legs, inclined struts, a core tube and viscous dampers. By additionally arranging the core tube, the overall rigidity of the structure is improved, and meanwhile the diameters of the guide pipe legs on the periphery are reduced, so that the ice force borne by the ocean platform is directly reduced, and the ice-induced vibration resistance of an offshore wind turbine is improved; the ice-induced vibration of the structure is reduced through the viscous damper; through the self-resetting system, the easily-yielded energy dissipation slotting assembly can be replaced to co
