<p>The blade installation system for large offshore wind turbines comprises multiple components and presents considerable operational challenges. This system primarily consists of the installation vessel, the ship-mounted crane, and the double pendulum system, with the transmission of dynamic responses among these components exhibiting significant complexity. Jack-up and floating installation vessels are widely deployed for the installation; however, different types of vessels will produce varying dynamic responses. These distinct responses serve as the motion boundaries of the installation system, ultimately affecting the blade oscillations. Therefore, this investigation develops an analysis program for blade installation and evaluates the dynamic responses of the system when different vessels are employed. The results indicate that, during operation with the jack-up vessel, blade oscillations are mainly governed by the first order mode frequency of the double pendulum system and the turbulent wind frequency. In contrast, when the floating vessel is utilized, the spectral peak frequency of the wave and the natural frequencies of the vessel must also be considered. Moreover, if the spectral peak frequency closely aligns with the first order mode frequency of the double pendulum system and the natural frequencies of the vessel, the blade oscillations will be significantly amplified.</p>
