Abstract

The blade installation system using the floating installation vessel comprises several parts, including the vessel equipped with the dynamic positioning system, the ship-mounted crane, and the double pendulum system. The interaction within the system will significantly impact the dynamic responses of the blade. To analyze the coupling responses of each part, the model-based design method is employed. The hydrodynamic analysis module of the installation vessel is built by the Cummins method, the kinematic module is constructed by the coordinate transformation and the double pendulum model, as well as the dynamic module is developed by the Lagrangian method. The aforementioned modules are integrated to develop the analysis program. By code-to-code comparison, the dynamic responses of the entire installation process can be accurately assessed by the program when the forces on the blade as well as the motion of installation vessel and ship-mounted crane are considered. In addition, the program can effectively improve calculation efficiency. In Part II of this paper, the dynamic responses of blade installation system are analyzed.
