[0002] Mooring chains are important equipment for offshore floating mooring and positioning. Steel chains have become an indispensable component in mooring systems due to their excellent load-bearing capacity, fatigue resistance and wear resistance. Traditional mooring system pre-tensioning uses anchor winches and chain stoppers, but they are costly and complicated to operate, and are not suitable for offshore floating wind turbine mooring systems. For floating production platforms or floating wind turbines, there is another method of achieving pre-tensioning by cooperating with cranes and chain stoppers, but this method has high requirements for the installation ship, is costly and difficult, and is not conducive to large-scale installation operations. In addition, the chain will produce a certain angle of deflection during use, which will bring non-axial forces to the joint between the chain and the platform (usually the connecting buckle), affecting its service life.
