Chain Stopper is a device for holding the anchor chain when a ship is at sea or at anchorage. It is made of high strength cast steel, with open links at one end and standard open pear-shaped links at the other end. The surface is treated with anti-rust spray paint, which has good anti-corrosion performance. The GL, LR and DNV codes require that the chain stopper should be able to withstand 80% of the min. breaking load of the chain through which it passes, in which case no permanent deformation will occur in the stressed part. It is suitable for single point mooring system and emergency towing system applications.
The OCIMF chain stopper is arranged on the deck between the windlass and the chain pipe to clamp the chain. After anchoring, the chain stopper can transfer the tension of the chain to the hull, so that the windlass is not under force. During navigation, the chain stopper bears the weight of the anchor and part of the chain, and will be attached to the hull by the anchor in the chain drum without collision. Therefore, the load force of the chain stopper base and its supporting structure is very large, and the rationality of its structure is directly related to the safety performance of the ship.
