Marine Mooring Solutions for Pearling Longline Systems

Optimized for Sustainable Pearl Farming Operations

1. Product Components

1.1 Anti-Biofouling Mooring Lines

• Application: Main tension-bearing lines connecting longlines to anchors

• Features:

• Material: Ultra-High Molecular Weight Polyethylene (UHMWPE) with ceramic nanoparticle coating

• Diameter Options: 20mm / 24mm / 28mm / 32mm

• Breaking Load: 12-45 tons (ISO 2307 certified)

• Anti-Fouling: Inhibits 90%+ marine organism attachment for 24+ months

• Purpose: Prevent line degradation and weight increase from barnacle/mussel colonization

1.2 Helix Anchors

• Application: Seabed fixation for longline systems in 10-50m depths

• Features:

• Material: Hot-dip galvanized steel with sacrificial zinc anodes

• Holding Capacity: 5T / 8T / 12T models

• 
  

• Installation: Rotary screwing technology (minimal seabed disturbance)

• Monitoring: Integrated load cell for tension feedback

• Purpose: Replace traditional concrete blocks with 3.5x higher holding power per unit weight

1.3 Modular Buoyancy System

• Application: Longline flotation and wave energy dissipation

• Components:

• Adjustable HDPE tubes (3-8m length) with quick-connect ends

• Integrated RFID tags for GPS mapping

• UV-stabilized high-density polyethylene

• Capacity: 50kg / 100kg / 200kg buoyancy grades

• Design: Low-profile shape with stabilizer fins to minimize windage

• HDPE Buoys:

• Buoy Spacer Tubes:

• Purpose: Maintain optimal longline depth (1.5-3m below surface) during tidal changes

1.4 Shock Absorption Connectors

• Application: Critical junction points between mooring lines/longlines

• Features:

• Material: Nitrile rubber + stainless steel shackles

• Energy Dissipation: 30-50% wave impact reduction

• Maintenance: Self-lubricating bearings (10-year service interval)

• Purpose: Protect oysters from sudden tension shocks during storms
