[0002] Existing wind turbine installation vessels have a limited number of turbine blades. Due to the frequent need to lower and position the pile legs during the operation process, and then retrieve them after the operation is completed, the wind turbine installation vessels need to precisely align the turbine head and blades during the installation process, which places high demands on the operation window. Therefore, existing wind turbine installation vessels have many unsolvable drawbacks in the current operating environment.

[0003] In addition, with the explosive growth of the wind power industry in recent years, many wind turbine legs have been damaged or disrepaired, resulting in damage to marine navigation area planning. If a vessel type could be developed that can transport the legs directly to the operating area and simultaneously recycle the existing wind turbine legs, such a vessel type would be of great use in the future.
