AI Technical Summary

Technical Problem

The existing mooring system of tension leg wind turbines has errors during the initial installation process, resulting in uneven stress, easy fatigue damage to the mooring chain, and even possible breakage, which affects the stability and safety of the platform.

Method used

A floating tension leg wind power platform is adopted, including a tension leg floating body and a tension balancing mechanism. Through the design of the hinge structure and rotating disk, the mooring components can be adaptively adjusted and balanced. Combined with the braking device and length adjustment component, a reliable locking structure is formed, which eliminates initial installation errors and improves the system's resistance to failure.

Benefits of technology

It achieves adaptive balancing of mooring tension, significantly improving the platform's operational safety and reliability, reducing construction and maintenance costs, and increasing installation efficiency.
