 I. Application Scenarios and Core Requirements
  1. Deep-Sea Cage Mooring Systems

    • Function: Anchor cages to withstand ocean currents, waves, and typhoon impacts, preventing drift or structural damage.
    • Challenges: Long-term immersion in high-salinity seawater, biofouling, and dynamic loads (cyclic tension variations).
    • Key Metrics: Tensile strength (≥800 MPa), corrosion resistance, fatigue resistance.
  2. Small Fishing Vessel Net Release and Emergency Use

    • Function: Rapid disentanglement from nets or emergency towing to avoid hull damage.
    • Challenges: Instantaneous shock loads, wear from frequent operations, and quick-release demands.
    • Key Metrics: Breaking strength (2-3× vessel tonnage safety factor), lightweight design, abrasion resistance.
II. Technical Selection and Design Considerations

1. Material Selection

  • Recommended Materials:
    • 316L Stainless Steel: Ideal for highly corrosive environments (e.g., deep sea) but costly.
    • Hot-Dip Galvanized Carbon Steel: Cost-effective; requires periodic coating inspections.
    • Alloy Steel (e.g., Grade 80/100): Ultra-high strength for extreme loads.
  • Corrosion Protection: Galvanization, epoxy coatings, or PVC/PE sheathing to extend lifespan and reduce biofouling.

2. Structural Design

  • Chain Link Types:
    • Short-Link Chains: Compact, high tensile strength, suitable for fixed mooring.
    • Long-Link Chains: Greater flexibility for dynamic load scenarios.
  • Accessories:
    • Swivels: Prevent twisting and reduce stress concentration.
    • Shackles: Enable quick connections; ensure material compatibility with chain grade.
    • Quick-Release Hooks: Critical for small vessels; prioritize single-handed operability.

3. Strength and Specification Matching

  • Deep-Sea Cages: Select chain diameter (20-50 mm) based on cage size, depth, and current speed. Breaking strength typically ranges from 200-1,000 tons (e.g., 30 mm Grade 80 chain: ~630 tons).
  • Small Vessels: Match chain diameter (12-20 mm) to vessel tonnage (e.g., 10-ton vessel requires ≥30-ton breaking strength).

4. Installation and Maintenance

  • Pre-Stretching: New chains should undergo pre-tensioning to eliminate manufacturing stress.
  • Inspections:
    • Visual Checks: Look for deformation, rust, or cracks.
    • Non-Destructive Testing (NDT): Magnetic particle or ultrasonic testing every 2 years.
  • Maintenance: Rinse with freshwater to remove salt; apply anti-corrosion grease (e.g., lithium-based).
 

III. Industry Standards and Certifications

  • International Standards:
    • ISO 1704: Specifications for ship anchor chains (materials and testing).
    • ASTM A975: Standards for galvanized steel chain strength and coating thickness.
  • Certifications: Prioritize products certified by DNV-GL, ABS, or equivalent marine classification societies.
 

IV. Cost Optimization and Alternatives

  • Hybrid Systems: Combine high-strength alloy steel for primary mooring with galvanized carbon steel for secondary chains.
  • Local Reinforcement: Add wear-resistant sleeves or enlarge links at stress points (e.g., connections).
  • Recycled Materials: Some manufacturers offer remanufactured chains (30-50% cost reduction); verify performance consistency.
 

V. Case Studies

  • Norwegian Deep-Sea Salmon Farms: Use 40 mm Grade 100 alloy chains with polyethylene sheathing, designed for 15-year service life, resisting 1.5 m/s currents.
  • Southeast Asian Small Fishing Vessels: Deploy 16 mm galvanized chains with quick-release hooks (40-ton breaking strength) for 10-ton vessels.
 

VI. Recommendations

  • Deep-Sea Priority: 316L stainless steel or Grade 80 alloy chains (≥30 mm diameter) with swivels and shackles; conduct regular NDT.
  • Small Vessels: Hot-dip galvanized carbon steel (12-20 mm diameter) with quick-release mechanisms; inspect quarterly.
  • Innovation: Smart chains with embedded sensors (real-time load/corrosion monitoring) for high-value aquaculture projects.

Proper selection and maintenance of fishery chains enhance operational safety, extend service life, and reduce long-term costs.
