We can also produce various non-standard chains and accessories, such as anchor shackle, Kenter Shackle, Joining Shackle, Buoy Shackle, Swivel Shackle etc. according to customer requirements.

Anchor Chain

The anchor chain is a cable chain connecting the anchor and the hull, which is mainly used to transfer the holding force of the anchor to offset the effect of external forces on the ship and ensure that the ship can be safely moored in the designated waters. The anchor chain consists of ordinary chain links, connecting chain links, connecting shackles, swivels, etc., and is divided into two types according to the structure of the anchor chain: with and without gears. The gear chain has a high tensile strength, and anchor rings with gear chains are generally used on ships; according to the manufacturing method, there are cast steel anchor chains, electric welding anchor chains and forged anchor chains. The quality of electric welding anchor chains exceeds that of other types of anchor chains, and the cost is also low, so it has been widely used.

Offshore Mooring Chain

Offshore mooring chains are equipment used for anchoring and positioning of marine facilities. They are life chains that ensure the normal use of marine facilities in severe sea conditions. Offshore mooring chains connect and fasten the surface structure to the seabed to ensure that the hull or floating platform stays at the required water level. Offshore mooring chains are mainly used in offshore oil drilling rigs, offshore oil production floating production systems, semi-submersible drilling platforms, single-point mooring structures, floating oil production and storage vessels and other offshore development facilities.
