The quality and specifications of anchor chains are critical for ensuring the safety and stability of marine operations.

Technical Features of Anchor Chains

When selecting an anchor chain, several technical features must be considered. Below is a comparison table highlighting the key technical specifications of anchor chains:

Feature	Description
Material	Typically made from high-strength steel, often galvanized for corrosion resistance.
Grade	Varies from Grade 2 to Grade 3, with Grade 3 offering higher tensile strength.
Diameter	Common diameters range from 16mm to 165mm, depending on the application.
Weight	Heavier chains provide better holding power; weight varies with diameter.
Certification	Must meet standards set by classification societies like ABS, DNV, and LR.
Breaking Load	The maximum load the chain can withstand before failure; varies by grade.
Link Type	Stud link and studless types are available, each with specific applications.

Types of Anchor Chains

Anchor chains come in various types, each suited for different marine applications. The following table outlines the primary types of anchor chains and their characteristics:

Type	Description
Stud Link Chain	Features protruding studs that provide additional strength and prevent links from twisting. Ideal for deep-sea applications.
Studless Chain	Lighter and more flexible, making it easier to handle. Suitable for shallow waters and lighter vessels.
High Holding Power	Designed for maximum holding capacity, often used in harsh conditions.
Galvanized Chain	Coated with zinc to prevent corrosion, extending the chain’s lifespan.
Stainless Steel Chain	Offers excellent corrosion resistance, ideal for marine environments.
