Anchor Line And Chain refers to the combination of rope and metal links used to secure a vessel's anchor. Anchor Chains are heavy-duty metal chains designed to withstand the forces of anchoring in marine environments. Both are critical for ensuring stability and safety when a ship is moored.

Size: 12.5 mm to 152 mm (0.5 inches to 6 inches) in diameter

Grade: Grade 2, Grade 3, ORQ (Oil Rig Quality), and High-Tensile Grades (e.g., Grade 30, Grade 40, Grade 60)

Viscosity: Not applicable (N/A) for chains, but lubricants used may have viscosities ranging from ISO VG 68 to ISO VG 460

Buoyancy: Negative buoyancy (sinks in water due to high-density steel material)

Material: High-strength carbon steel, alloy steel, or stainless steel (e.g., ABS, LR, DNV certified)

Breaking Load: Varies by size and grade (e.g., 12.5 mm Grade 2 chain has ~32 kN, while 76 mm Grade 3 chain has ~5,400 kN)

Proof Load: Typically 50% of breaking load (e.g., 16 kN for 12.5 mm Grade 2 chain)

Surface Treatment: Hot-dip galvanized, painted, or bare steel with anti-corrosion coatings

Link Types: Studlink (common for mooring), Studless (for towing), or Detachable links

Standards: Complies with ISO 1704, ABS, DNV, Lloyd’s Register, or other maritime classifications

Weight: Varies by size (e.g., 12.5 mm chain weighs ~2.2 kg/m, 76 mm chain weighs ~122 kg/m)

Elongation: Minimal under working load, but designed to withstand dynamic forces

Corrosion Resistance: Enhanced by galvanization or stainless steel material

Testing: Certified via destructive/non-destructive testing (e.g., MPI, UT, load testing)
