Smart Berthing Systems with Adaptive Foam Fender Design

1. Introduction

Modern ports need safe, efficient, and green berthing systems. Foam fenders are key. They absorb energy and protect structures. NANHAI builds smart foam fender systems that adapt in real time. These systems improve performance and reduce costs.

2. Foam Fender Basics

1. Structure & Material:
   We use closed-cell EVA foam cores covered with elastic jackets. They are lightweight, absorb energy well, and resist fatigue and rough environments.
2. NANHAI Product Line:
   We offer models like Ocean Defender, Armored Defender, Donut Fender, and rubber-coated foam fenders. Each model fits different ship types and berthing needs.

3. Factors Affecting Foam Fender Behavior

1. Compression Set & Creep:
   Foam can compress over time and lose its ability to bounce back. This reduces energy absorption.
2. Density, Layering & Cover Strength:
   Higher density or stronger layers can increase performance. But covers must also resist wear and tear.
3. Harsh Environment:
   Salt, UV light, and temperature changes (from –50 °C to -70 °C) can damage materials and reduce lifespan.

4. NANHAI’s Adaptive Design Strategy

A. Real-Time Monitoring

We install sensors that measure fender movement and stress. These sensors feed data to a control system. It works with SCADA following industry standards like PIANC WG211.

B. Simulation & Energy Analysis

We use PIANC WG211 guidelines to calculate energy needs. We then run FEA and CFD simulations. This lets us optimize foam structure.

C. Modular & Parametric Structure

We build fenders in modules with different hardness levels. If berthing needs change, we can swap or adjust modules easily. This also makes maintenance simpler.

D. Control & Feedback Loop

Our pneumatic and PLC systems monitor wear and performance. They automatically adjust fender settings. The system also alerts teams when maintenance is due.

5. Case Studies

• Ocean Defender Series:
  Lightweight and flexible, this system adjusts quickly to different berthing forces.
• Donut Fender:
  Its soft-hard design and circular shape reduce stress on both ships and structures.

6. Benefits & Market Advantage of Foam Fender

1. Higher Efficiency, Lower Cost:
   Adaptive control means less permanent damage and fewer repairs.
2. Robust in Extreme Conditions:
   High-density foam and protective jackets resist salt, UV, and temperature swings.
3. Standard Compliance:
   We follow PIANC WG211 rules. This makes our design accurate and trusted.

7. Toward Smart Ports

• Green Goals:
  With better energy absorption and longer life, we reduce waste and carbon output.
• Digital Operations:
  We connect fender data to the port IoT and control systems. Remote monitoring and alerts are possible.
• Global Reach:
  With 20 years in foam fenders and exports to over 80 countries, NANHAI leads the way in smart port tech.

8. Summary & Call to Action

NANHAI’s smart foam fender systems adapt to changing forces. They boost safety, lower costs, and last longer.

Next steps:

• Port designers: choose NANHAI adaptive fenders and use WG211 guidelines.
• Operators: connect our fenders to dock protection systems.
• Integrators: link fender data into your systems for alerts and maintenance.
