La ciencia de las defensas cónicas: Compresión, deflexión y cizallamiento

Why This Matters More Than Ever

As global trade grows, so do ships, and the impact forces they bring to your dock. For example, when a 200,000 DWT vessel docks at a slight angle, standard fenders can deform unevenly or even fail. Therefore, the urgency for smarter marine fender systems has never been greater. At NANHAI, we help terminals reduce risks and costs by using Defensas Super Cone built for real-world challenges.

What Makes Super Cone Fenders Scientifically Superior?

They Perform Under Angled Compression
Thanks to their unique shape, Super Cone Fenders handle impacts from various angles without losing energy absorption. In contrast to traditional fenders, they compress evenly, even up to 10°, making them ideal for large ships approaching at awkward angles.

They Absorb More with Controlled Deflection
Super Cone Fenders deflect up to 74% of their height. This large deflection helps absorb massive impact energy while keeping reaction forces low. As a result, they protect both the dock and the ship more efficiently.

They Resist Shear Forces Effectively
Their wide base adds strong resistance against vertical and horizontal shear. While some situations still call for shear chains, the geometry alone often ensures stability. Therefore, these fenders are reliable even under high lateral loads.

They Include Built-In Overload Stops
To prevent damage from over-compression, many Super Cone Fenders include overload stops. These features act like safety brakes, ensuring your fender system stays within design limits.

Fragmentos destacados

What is the compression angle of a Super Cone Fender?
Super Cone Fenders work effectively even at 10° compression, maintaining performance without stress concentration.

How much deflection can they handle?
They handle up to 74% deflection, delivering high energy absorption and low reaction force.

Can they resist shear?
Yes. Their structure resists lateral and vertical shear naturally, often without needing extra chains.

Technical Highlights

1. Better Shape, Better Energy Control

Their conical design spreads impact force evenly. In comparison, flat-panel fenders often concentrate stress in one area, increasing failure risk.

2. Engineered Materials for Any Climate

NANHAI uses various rubber types—such as SBR and EPDM—to suit hot, cold, or abrasive conditions. This flexibility ensures our defensas marinas work anywhere.

3. Real Testing Before Deployment

Each fender goes through lab compression, shear, and overload testing. Our engineers confirm performance before it reaches your dock.

PREGUNTAS FRECUENTES

How are Super Cone Fenders different from cell fenders?
They use a cone shape, offering better deflection, angle tolerance, and energy absorption.

Can you retrofit Super Cone Fenders?
Yes. Most ports can upgrade without major changes, making them ideal for modernization.

What sizes are available?
Standard sizes range from 300 mm to 2,000 mm in height.

Are they suitable for LNG docks?
Absolutely. They’re used in LNG, RoRo, container, and oil terminals worldwide.

Conclusion: Choose NANHAI for Safer Docks

In today’s shipping world, outdated fenders can cost millions. At NANHAI, we engineer Defensas Super Cone to handle angle, deflection, and shear—without compromise. So if you’re planning a port upgrade or building a new terminal, let our defensas para barcos give your operation the safety and reliability it deserves.
