Mooring systems in the fixing element (chain or vault) is a product used between rope. The main task of the chain is to keep the fixing element in line with the continuous floor and help to secure the mooring by its weight. The size and weight of the chain to be used should be at least the weight of the fixing element. In high-risk mooring systems, this ratio should be increased to 1.5 times or even twice. The fuse of the fastening element is a chain. In order to reduce the investment costs of the chain to be used, the strength values can be obtained from the ship dismantling facilities without being below 80%. The links between the float and the collector are also used in the connection between the cage and the mooring, except for the connection of the fixing element.
