Furthermore, if extremely severe sea conditions occur causing the damper to fail, damage will be limited to occur in the damper, the disc springs will first fail, thereby protecting the platform's overall mooring system from damage. If an accident occurs, the ocean platform can be continuously used only by replacing the damper, and the ocean platform is very convenient. The utility model can be better adapted to the ocean environment, so that the ocean platform can safely run.
