Anchor chain sizing involves selecting the appropriate diameter and length based on vessel size and environmental conditions. The chain's strength and weight must balance holding power with manageable handling. Proper sizing ensures safe anchoring and compliance with maritime regulations.

Anchor Chain Sizing: Diameter ranges from 10mm to 200mm, depending on vessel size and mooring conditions.

Grade: Common grades include Grade 2, Grade 3, and High-Tensile (HT) chains (e.g., Grade 30, Grade 40).

Viscosity: Not applicable to anchor chains; viscosity is a fluid property.

Buoyancy: Anchor chains are negatively buoyant, typically made of steel with a density of ~7.85 g/cm³.

Material: Typically forged carbon steel or alloy steel, often galvanized for corrosion resistance.

Length: Standard shots are 27.5 meters (90 feet), with total length varying based on water depth and requirements.

Proof Load: Minimum breaking force varies by grade (e.g., Grade 3: 700 N/mm², HT Grade 40: 1,370 N/mm²).

Weight: Approximate weight ranges from 2 kg/m (10mm) to 300 kg/m (200mm).

Corrosion Protection: Hot-dip galvanizing or specialized coatings for marine environments.

Testing: Certified to standards like ISO 1704, ABS, DNV, or Lloyd’s Register.
