Underwater anchor retrieval involves locating and recovering lost ship anchors and chains from the seabed. Specialized divers or ROVs are used to handle the heavy equipment and secure it for lifting. The process ensures safe and efficient recovery while minimizing environmental impact.

Size: Typically ranges from 1 to 10 meters in length, depending on anchor and chain size.

Grade: High-strength steel (Grade 2 or Grade 3) for chains, with forged steel for anchors.

Viscosity: N/A (not applicable for solid retrieval systems).

Buoyancy: Neutral to slightly negative buoyancy for submerged retrieval tools.

Material: Corrosion-resistant alloys (e.g., galvanized steel, stainless steel, or coated carbon steel).

Chain Diameter: 20mm to 150mm, depending on vessel size.

Anchor Weight: 50kg to 20,000kg, based on ship class.

Recovery Load Capacity: 5 to 500 metric tons, depending on equipment.

Corrosion Resistance: High (marine-grade coatings or stainless steel).

Operating Depth: Up to 300 meters for standard systems, specialized versions go deeper.
