[0002] As the global demand for renewable energy increases, offshore wind power has been widely used and developed as a clean and efficient form of energy. Offshore wind power equipment usually carries wind turbines on floating platforms, and connects the floating platforms to the seabed through cables and anchors to form a stable working platform. Offshore water electrolysis hydrogen production equipment is powered by wind power equipment on it, further improving energy efficiency and environmental protection performance.

[0003] Although offshore wind power equipment has made significant technological progress, it still faces some challenges in practical application, especially in harsh marine environments. Strong winds and waves at sea often cause the floating platform to tilt, which poses a serious threat to the stability and safety of wind power equipment. Existing solutions mainly focus on improving the buoyancy structure of the floating platform to improve its ability to resist tilting. However, due to the high center of gravity of the tower and blades supported on the top of the floating platform, the buoyancy structure of the floating platform alone cannot fully meet the requirements of resisting tilting, and there are mainly the following defects: 1. Although the existing floating platform design has improved its anti-tilting ability to a certain extent, it is still difficult to fully control the tilting of the platform in strong winds and waves due to the high center of gravity of the tower and blades; 2.
