The Chain Cable is a steel chain that connects the hull to the anchor. The main function of the anchor chain is to connect the anchor to the ship and transmit the anchoring force of the anchor to the hull. When anchoring, the anchor chain has a certain weight, which can play a certain role in the water and other external forces received by the ship. The buffering effect; the anchor chain of the horizontal bottom part maintains the horizontal force of the anchor, which is beneficial to the reliable bottoming of the anchor. At the same time, this part of the chain can also provide a part of the anchoring force due to the blockage of the soil.
