Safety Chain Anchor in Peter I Island, Emergency Generator Controllers - Anchor Chains

The Safety Chain Anchor is a secure attachment point used to fasten anchor chains, ensuring stability and safety. Anchor chains are heavy-duty chains designed to connect anchors to vessels, providing reliable mooring. Both components work together to prevent drifting and enhance maritime security.

Safety Chain Anchor:

- Size: Typically 12.5 mm to 76 mm diameter

- Grade: Grade 2, Grade 3, or High-Tensile (HT) steel

- Material: Forged or cast steel, often galvanized for corrosion resistance

- Working Load Limit (WLL): Varies by size and grade (e.g., 1.5 to 200 tons)

- Breaking Strength: 4-6 times WLL depending on grade

Anchor Chains:

- Size: 13 mm to 152 mm diameter (common marine sizes: 19 mm to 76 mm)

- Grade: Grade 2, Grade 3, or High-Tensile (HT) steel (e.g., U2, U3, K3, K4)

- Material: Carbon steel or alloy steel, often hot-dip galvanized

- Viscosity: N/A (chains are solid, no fluid properties)

- Buoyancy: Negative (submerged weight ~2.5-3.0 times in air due to water displacement)

- Proof Load: 50-70% of breaking strength (e.g., 32 mm G3 chain: ~1,250 kN proof load)

- Breaking Strength: Varies by size/grade (e.g., 22 mm G3 chain: ~690 kN)

- Stud Link: Common for marine applications (studs prevent chain kinking)
