As someone who has spent years working alongside shipyard engineers and port operators, I've seen firsthand how marine rubber fenders can make or break a vessel's safety. When a cargo ship weighing over 100,000 tons approaches a berth, the kinetic energy involved is staggering. Without properly designed pneumatic fenders and marine airbags, you're looking at potential hull damage, structural failure, and millions in repair costs.
The marine industry has evolved significantly, and at Nanjing Taidun Marine Equipment Engineering Co., Ltd., we've been at the forefront of this evolution. Our Yokohama-type pneumatic fenders and ship-launching airbags are engineered to meet the toughest standards, from ISO 17357-1:2014 to PIANC 2002 type approval .

When a vessel berths, the marine fender must absorb kinetic energy and convert it into compression energy. The key metrics are reaction force and energy absorption – and they determine how well your dock or shipyard equipment performs under pressure.
At Nanjing Taidun, our rubber fenders are engineered with a compression set of ≤8%, compared to the industry average of 12-15% . What does this mean in practice? After a decade of service, our fenders maintain near-original performance, while competitors' products degrade significantly.
Real-world user feedback:
We installed Nanjing Taidun fenders at our container terminal in 2019. Seven years later, we measured compression set at under 6%. The fenders still perform like new. Our previous supplier's fenders showed 14% set after just 5 years." – Technical Director, Southeast Asian Port Authority
The rubber compound is the heart of any marine rubber fender. We use premium vulcanized compounds including EPDM and neoprene, processed through German-engineered mixers with precise temperature control (±2°C) during vulcanization .
This attention to detail yields:
- Tensile strength: 22-25 MPa (industry average: 18-22 MPa)
- Shore A hardness: ±3 tolerance (industry average: ±5)
- Service life: 15-20 years (industry average: 8-12 years)

Pneumatic rubber fenders are the gold standard for ship-to-ship (STS) transfers and large vessel berthing. They consist of an inflatable rubber body with an internal air chamber that provides excellent energy absorption with relatively low reaction force.
Our pneumatic fenders range in size from 0.5m × 1.0m to 4.5m × 12.0m, with energy absorption capabilities up to 6,473 kJ at 60% deflection . The two main types – Type I (net type) and Type II (sling type) – accommodate different facility requirements .
Key advantages:
- Excellent energy absorption-to-weight ratio
- Adjustable performance via internal pressure control
- Suitable for areas with tidal differences
- Lower transportation costs compared to solid fenders
Foam-filled fenders are another robust option. They're constructed with closed-cell energy-absorbing resilient foam laminated layers, reinforced with nylon filament, and covered with tough polyurethane skin . These can absorb up to 40% more energy than similarly sized pneumatic fenders, making them ideal for rugged environments .
| Feature | Pneumatic Fenders | Foam Fenders |
|---|---|---|
| Energy Absorption | High | Very High (up to 40% more) |
| Maintenance | Requires air pressure monitoring | Low maintenance |
| Weight | Lightweight | Heavier |
| Installation | Standard | Standard |
| Best Use Case | STS operations, large ships | Offshore, permanent docks |
Every marine project is unique. That's why we begin our design service with a thorough analysis of your requirements:
Required Information:
1. Ship specifications: Type, length (min/max), width, draft
2. Berthing conditions: Approach speed, berthing angle
3. Environmental factors: Tidal range, wave height, exposure to storms
The difference in bollard quality was immediately visible. Our old bollards had rust after 2 years. The Taidun hot-dip galvanized bollards are still rust-free after 6 years in the same corrosive environment.– Facility Manager, Middle East Terminal
We provide comprehensive installation support, including:
- Technical manuals with step-by-step instructions
- 24/7 online support for troubleshooting
- On-site engineering supervision (available upon request)
Typhoon season poses an existential threat to ports worldwide. High winds, towering storm surges, and erratic vessel movement can cause catastrophic damage. In a recent case study, a major deep-water port faced its most intense storm season in a decade – and emerged with zero critical infrastructure damage .
How our rubber fenders performed:
- Zero structural damage to quay walls and berths
- No vessel hull impacts
- Minimal maintenance required post-storm
The port's facility manager noted that their previous, outdated fenders required frequent repairs and failed to buffer heavy impacts. After switching to our ISO 17357 and PIANC certified fenders, they achieved near-uninterrupted operations during peak typhoon season .
At Nanjing Taidun, quality isn't just a promise – it's backed by internationally recognized certifications:
| Certification | Scope |
|---|---|
| ISO 9001:2015 | Quality management system |
| BV (Bureau Veritas) | Product testing and inspection |
| SGS | Material verification |
| PIANC 2002 | Type approval for marine fenders |
| LR, ABS | Marine product certification (upon request) |
Every batch undergoes rigorous testing per international standards:
- ASTM D395: Compression set testing
- ASTM D2240: Shore hardness measurement
- ASTM D412: Tensile strength and elongation
Our facility spans 30,000 square meters with an annual production capacity of 8,000 tons of rubber fenders and 1,000 tons of steel structures . We've supplied marine fender systems to over 80 countries and completed more than 1,000 projects worldwide .
Unlike many suppliers who only provide products, Nanjing Taidun delivers complete end-to-end solutions:
1. Design consultation and engineering
2. Manufacturing with strict quality control
3. Transportation logistics coordination
4. Installation support and supervision
5. After-sales service and maintenance guidance
