Core Structural and Material Advantages
Structural design optimized for offshore conditions: Features a “four-claw anchor crown + crossbar positioning” structure with symmetrical curved claws and an optimal deployment angle. This enables rapid embedding into seabed sediments (suitable for silt, clay, and gravel substrates) during seabed engagement. The crossbar prevents lateral rollover, enhancing seabed stability. Reinforced crown design enhances impact resistance, withstanding harsh offshore wind and wave conditions.
High-strength, corrosion-resistant materials: Main body cast from high-strength steel (e.g., ZG230-450) or marine-grade carbon steel, featuring integral casting with tensile strength ≥400MPa to endure extreme offshore mooring stresses. Surface treated with sandblasting for rust removal + epoxy zinc-rich primer + marine-grade topcoat, or hot-dip galvanizing process, providing resistance to seawater corrosion and salt spray erosion for long-term offshore service.

Manufacturing Process:

The production process of Admiralty Anchors strictly adheres to marine anchor casting standards and offshore mooring equipment strength requirements, centered on “structural precision, material strength and toughness, and corrosion resistance compliance.” Specific steps are as follows:

### 1. Raw Material Preparation and Mold Design
- Select high-strength cast steel (ZG230-450) or premium marine carbon steel. Ingredients are blended according to chemical composition requirements to ensure compliance with carbon, manganese, and other elemental content standards, enhancing tensile strength and toughness.
- Design sand molds based on anchor specifications (weights ranging from 500kg to 50t). The mold cavity precisely replicates the naval anchor's “four-fluke crown + crossbar” structure. Thickened sections are incorporated at the anchor fluke-to-shank junctions. Mold inner walls undergo polishing to prevent surface defects in castings.

### 2. Monolithic Casting
- Molten cast steel (1500-1600°C) is injected into the mold via a pouring system using gravity casting. This ensures uniform filling without dead zones or porosity.
- After natural cooling to room temperature, the mold is opened to remove the anchor blank. Gates, risers, flash, and other excess material are trimmed to prevent residual stress-induced cracking.

### 3. Structural Reinforcement and Precision Machining
- Critical load-bearing areas like anchor claws and crown undergo forging reinforcement to enhance localized hardness and impact resistance. Claw edges are ground to ensure sharpness and improve seabed gripping efficiency.
- Machine the connection hole at the top of the anchor body (to match anchor chain specifications). Bore the hole walls smooth to ensure secure chain attachment. Secure the crossbar via welding or integral casting. Apply full-penetration welding at joints and perform non-destructive testing.

### 4. Surface Anti-Corrosion Treatment
- Perform sandblasting rust removal first to thoroughly eliminate surface scale, rust, and oil contamination, achieving Sa2.5 standard to enhance coating adhesion.
- Apply a dual-layer coating of “epoxy zinc-rich primer + marine-grade topcoat” (total thickness ≥150μm) or utilize hot-dip galvanizing (zinc coating thickness ≥85μm). Both methods effectively resist offshore seawater corrosion and salt spray erosion.

### 5. Finished Product Inspection and Quality Control
- Visual Inspection: Verify anchor body is free of cracks, pores, pinholes, or other defects. Structural dimensional deviation ≤ ±3%. Anchor fluke symmetry and crossbar verticality meet design requirements.
- Performance Testing: Conduct tensile strength testing (≥400MPa) and impact toughness testing. Perform simulated holding force tests on samples to verify holding force meets standards (≥8 times its own weight).
- Corrosion Resistance Testing: Pass salt spray testing (1000 hours continuous) to evaluate coating or galvanized layer durability, meeting offshore long-term service requirements.
- Compliance Certification: Products must obtain certification from classification societies such as CCS and ABS, ensuring compliance with GB/T 5468-2019 “General Technical Conditions for Marine Anchors” and offshore mooring equipment standards.

### 6. Packaging and Shipping
- Packaged securely on wooden pallets or steel frames to prevent deformation during transit. Anchor bodies are wrapped in moisture-proof film to protect anti-corrosion coatings.
- Includes product inspection reports, certification documents, and installation manuals for seamless offshore project integration or on-site deployment.

Features:

Fast and Efficient Mooring with Superior Holding Power: Featuring sharp flukes and a large bearing surface, this anchor rapidly sinks and cuts into the seabed upon immersion. Its holding power reaches 8-12 times its own weight, delivering over 30% higher efficiency than conventional anchors. This enables swift and stable mooring, making it ideal for temporary offshore platform berthing or emergency vessel mooring.
Outstanding Stability and Wave Resistance: The symmetrical four-fluke design distributes forces evenly. Even under severe offshore winds, waves, and strong currents, it maintains a secure anchoring posture without loosening, preventing “dragging anchor” risks and ensuring stability for moored objects (e.g., offshore platforms, engineering vessels).
Robust construction with extended service life: The integrated casting process eliminates welded joints. Reinforced connections between flukes and the anchor body provide high fatigue strength, enabling repeated resistance to mooring tension impacts. Post-corrosion treatment extends normal offshore service life to 15-20 years with low maintenance costs.
Wide adaptability and easy operation: Sizes range from several tons to hundreds of tons (anchor weights 500kg-50t), accommodating various tonnage equipment like offshore platforms, engineering vessels, and drilling ships. When paired with high-strength anchor chains, anchoring and weighing anchor operations are straightforward, requiring no complex auxiliary equipment.

Technical Parameters:

Applications:

Offshore Platform Mooring: Used for temporary or long-term mooring of offshore wind platforms and oil/gas drilling platforms. Multiple naval anchors are deployed in coordination to secure the platform's position and withstand the impact of sea winds, waves, and ocean currents.
Offshore Engineering Operation Mooring: Designed for rapid mooring needs of offshore engineering vessels (e.g., crane ships, supply vessels) during operations, ensuring stable berthing for safe offshore construction and equipment transfer.
Offshore Emergency Mooring for Vessels: Serves as emergency mooring gear for ocean-going vessels and research ships in offshore zones. Enables rapid anchoring during emergencies to prevent uncontrolled drift.
Offshore Floating Structure Mooring: Secures floating assets like offshore buoys, floating docks, and aquaculture platforms. Utilizes strong seabed grip to prevent displacement, adapting to complex offshore hydrographic conditions.
