What is an anchor chain and what is the purpose of an anchor chain?
Anchor chain is a steel chain that connects the hull of a ship to an anchor.
The main functions of the anchor chain are: to connect the anchor and the ship, and to transmit the anchor's gripping force to the hull; When anchoring, because the anchor chain thrown out has a certain weight, it can play a certain role in buffering the external forces such as wind currents on the ship in the water; The force of the anchor chain on the anchor is kept horizontal, which is conducive to the reliable grip of the anchor.
At the same time, this part of the anchor chain can also provide a part of the anchoring force due to the blocking effect of the soil.
Anchor chain refers to a special chain that connects the anchor to the hull and transmits the anchor grip. It is often composed of anchor end links, intermediate links and end links.
According to the structure of the chain link, it can be divided into two types: geared anchor chain and non-gearless anchor chain, the former has greater strength than the latter; According to the manufacturing method, anchor chains can be divided into cast steel anchor chains and welded anchor chains.
The length of the anchor chain is measured in knots, and the standard length of each anchor chain is 27.5m.
The internodes are connected with a connecting chain link or a connecting shackle. Usually, the chain length of the main anchor on each side of the 10,000-ton ship is about 12 knots.
