Description

Technical Field

[0001] This utility model relates to the field of offshore wind power, specifically a tension leg platform system with a tendon balancing device. Background Technology

[0002] Currently, most offshore wind power platforms are designed using tension leg platforms (TLP) structures, which are widely used in the offshore wind power field. However, although tension leg platforms can effectively withstand certain static loads, they still face many challenges in actual operation. Especially in dynamic environments, the platform is often subjected to external factors such as wind, waves, and currents. These factors cause uneven stress on the platform, which may lead to tilting and vibration, affecting its overall stability and power generation efficiency.

[0003] In existing technologies, many tension leg platforms are designed without adequately considering the changes brought about by dynamic loads. They typically resist external forces by increasing the platform's self-weight, optimizing the anchoring system, or enhancing the rigidity of the tendons. However, these designs often rely too heavily on the stability of the static structure and fail to adequately address the unevenness of the platform's dynamic response in complex environments. For example, while increasing the tension of the tendons can improve the platform's balance to some extent, it may also lead to local instability when facing strong winds and waves, potentially causing equipment damage or failure.

[0004] Therefore, existing technologies still face significant challenges under real-world operating conditions, especially in extreme sea states and complex weather conditions, where the platform's stability and continuous operation capabilities remain insufficient. To address this issue, this application proposes an innovative solution that dynamically adjusts the stress on the tension legs, enabling the platform to respond in real-time to changes in external loads and maintain a more stable posture. Through precise control of the tendon stress, this solution effectively prevents platform tilting and vibration, thereby significantly improving the platform's overall stability and power generation efficiency.
