Introduction to Lambda Fenders

Lambda fenders, also known as V fenders or Arch fenders, are high-performance and versatile marine fenders. Developed using advanced engineering methods, Lambda fenders provide superior energy absorption while maintaining low reaction forces.

Compared to traditional V fenders, Lambda fenders offer 26% higher energy absorption with the same reaction force, making them ideal for ports requiring effective load and deflection management.

Lambda fenders can withstand up to 52.5% deflection, making them suitable for both small and large vessels. Their flexible design allows horizontal or vertical installation, depending on jetty structure. Built with durable and reliable materials, they ensure long service life even under harsh marine environments.

For maximum safety, Lambda fenders are typically anchored deep into concrete, ensuring stability. Their unique combination of high energy absorption and low reaction forces minimizes damage to both vessels and port infrastructure.

Nguyen Tai’s Lambda fenders are designed for customized installations with options such as chemical anchor bolts or mechanical bolts, helping ports optimize operations, reduce maintenance costs, and ensure long-term reliability.

Installation Guide for Lambda Fender

  1. Preparation

    • Determine installation location based on design drawings.

    • Ensure concrete surface is clean and obstacle-free.

    • Prepare tools: anchor bolts, chemical adhesives (Sika), lifting equipment.

  2. Anchor Bolt Installation

    • If embedded during concrete casting: ensure correct alignment and secure fixing.

    • For post-installation: use chemical anchors or epoxy adhesives for maximum strength and safety.

  3. Fender Installation

    • Position fender correctly, aligning bolt holes with anchors.

    • Use cranes or lifting boats for large, heavy fenders.

  4. Bolt Tightening

    • Use torque tools to tighten anchor bolts.

    • Ensure fender is firmly secured without displacement.

  5. Inspection & Maintenance

    • Verify all bolts are tightened to required torque.

    • Confirm installation matches design drawings and safety standards.

    • Perform regular inspections to ensure durability and long service life.

Quality of Lambda, V, and Arch Fenders

  • Durability & Reliability: High-grade rubber, excellent energy absorption, and low reaction forces.

  • Proven Design: Arch fenders have been used since the 1960s for reliable port protection.

  • Optional Low-Friction Pads: UHMW-PE pads reduce vessel-fender friction, extending product lifespan.

  • Wide Applications: Suitable for RoRo terminals, general cargo berths, tugboat berths, and heavy-duty ports.
