Understanding the mechanics of an anchor chain is key to appreciating its role in anchoring operations. When the anchor is dropped, the chain pays out, allowing the anchor to settle on the seabed. As the ship moves backward, the chain gradually extends, forming a catenary - a horizontal curve shaped by the weight and tension of the chain. The catenary acts as a shock absorber, distributing the forces exerted on the anchor and reducing strain on both the anchor and the vessel.

The anchor chain consists of many chain links, and the size is expressed in chain diameter (mm). According to whether there is a strut in the middle of the chain ring, it is divided into nailed anchor chain and nailless anchor chain. Anchor chains can be made by forging, casting and welding.

The marine anchor chain is composed of several "sections" (shackles), each section is 25.0-27.5 meters long, and the sections are connected by chain links or shackles. After the anchor is lifted, the chain is stored in the chain locker in the bow. The specifications of the anchor chain are determined according to the ship construction standard.

The anchor plays a major role in a vessel and offshore operations. However, it can only function as long as it remains attached to the floating structure.

Considering the tremendous amounts of force applied to the connection between the anchor and the ship during routine berthing or anchoring conditions, conventional methods of securing the anchor will eventually fail under the extensive stress.

The anchor chain refers to the component that attaches the anchor to the boat or structure and is usually referred to as the anchor rode (or anchor cable). It is superior to conventional methods in terms of strength and load-bearing.

A ship's anchor chain plays a critical role in ensuring the vessel's stability and safety while at rest. A reliable anchor chain provides the necessary strength and support to withstand the forces exerted by wind, waves, and currents. It acts as a vital link between the ship and the anchor, transmitting the anchor's holding power to keep the vessel secure.

To ensure the anchor chain's reliability, it must be constructed from high-quality steel and designed to withstand the harsh marine environment. The chain's size and weight are determined based on the ship's size and requirements, with larger ships typically requiring thicker and heavier chains. Regular maintenance and inspections are crucial to identify any signs of wear, corrosion, or damage that could compromise the chain's integrity. By prioritizing the reliability of the anchor chain, ships can anchor with confidence and maintain their position even in challenging conditions.
