Subsea Buoyancy Low Water Absorption Floating Underwater Floating Cable Dock Cable Floats Rope Buoy

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Subsea Buoyancy Support: Designed to provide reliable buoyancy for underwater cables, ropes, and marine equipment, ensuring stable positioning in aquatic environments.
  • Low Water Absorption: Engineered with advanced rubber composites to minimize water ingress, maintaining structural integrity and functionality in submerged conditions.
  • Cable Dock and Float Solutions: Secures and elevates underwater cables or ropes, preventing entanglement and damage while facilitating easy deployment and maintenance.

Key features

  • 1. Advanced Material Technology for Enhanced Durability

    • With a corrosion-resistant composite material and low water absorption design, you can ensure prolonged subsea performance without degradation. This material outperforms traditional rubber-based buoys by reducing water absorption by ~20%*, making it ideal for harsh marine environments.

  • 2. Modular Design for Easy Cable Management

    • With a secure, stackable cylindrical design, you can quickly install and adjust buoyancy for underwater cables. The uniform shape allows for seamless stacking, enabling 30% faster deployment than non-modular alternatives*.

  • 3. High Buoyancy & Load Capacity

    • With a reinforced structure optimized for subsea use, you can support heavy-duty cables and equipment with up to 50% greater load capacity than standard foam floats*. The robust molding process ensures stability in deep-water applications.

  • 4. Visibility-Enhanced Safety for Commercial Use

    • With a bright orange color and uniform cylindrical shape, you can improve safety during underwater maintenance or commercial operations. The high-visibility design reduces the risk of collisions or misplacement in low-light marine environments.

  • 5. Eco-Friendly & Marine-Certified Materials

    • With eco-friendly composite materials and compliance with marine safety standards (e.g., ISO 20730), you can meet environmental and regulatory requirements for underwater equipment.

Product details

Subsea Buoyancy Low Water Absorption Floating Underwater Floating Cable Dock Cable Floats Rope Buoy

Supplier's note

  1. Technical Breakthroughs:

    • Low Water Absorption: The Pro model’s ≤0.01% absorption rate outperforms industry benchmarks, preventing buoyancy loss in prolonged submersion.
    • Modular Design: Uniform dimensions allow seamless integration into existing systems, reducing downtime.
    • Corrosion Resistance: Advanced composite materials exceed ISO 20677 standards, extending lifespan in saltwater.

  2. Version Selection Guide:

    • Base Model: Ideal for standard dock installations or light-duty applications (e.g., recreational boat mooring).
    • Advanced Model: Suitable for commercial marine operations requiring enhanced durability, such as offshore wind farm cabling.
    • Pro Model: Engineered for extreme environments (e.g., deep-sea oil rigs) with triple the industry-standard chemical resistance, ensuring safety in harsh conditions.

With the Pro model’s 78 kg/m³ buoyancy, you can safely deploy heavy-duty subsea cables in depths exceeding 500m. Pair its reinforced composite material with anti-fouling coatings to minimize maintenance and maximize operational uptime.
