We welcome you to choose Aorunda as your supplier. Our Port Polyurethane Fenders are reliable, durable, and have become the designated protection solution for over 300 large ports and more than 20 international hub ports worldwide.
Due to the high-intensity impact requirements when large vessels berth at ports, we have upgraded our product's polyurethane foam technology to achieve precise density control of 700-850 kg/m³, combined with a unique conical or fan-shaped structural design. The rated deformation rate reaches 72%, far exceeding the 52.5% of traditional cylindrical fenders.
During ship impact, the molecular chains undergo multi-layer deformation, absorbing more than 95% of the impact force, resulting in a surface pressure value as low as 250 kPa. The recoil force is reduced by 50% compared to traditional rubber fenders, completely eliminating the problem of hard-on-hard impact damage.
Our products are primarily used in port environments, facing high salt spray, strong ultraviolet radiation, and alternating tidal changes, which pose a severe test to the durability of fenders.
Aorunda's Port Polyurethane Fenders utilize a weather-resistant formula, incorporating UV absorbers and corrosion inhibitors. They can operate stably in extreme temperatures ranging from -40℃ to 85℃ and are resistant to seawater immersion, oil contamination, and microbial erosion.
Actual use case:
In a project at Chancay Port in Peru, where wave heights are known to reach up to 4 meters and strong surges frequently occur, our fenders withstood high-frequency wave impacts for four consecutive years with a performance degradation rate of only 3%. Under normal operating conditions, their service life is 12-15 years, three times longer than traditional rubber fenders, significantly reducing downtime and replacement costs.
The protection requirements vary significantly across different areas of port facilities, including dock lines, mooring piles, corner positions, and approach bridges. We offer six exclusive structures: conical, fan-shaped, rectangular, and cylindrical, with thicknesses ranging from 50mm to 500mm and lengths from 0.5m to 10m, customizable to your needs.
Recommended Structure Selection:
The conical version is suitable for the main berthing areas of large vessels, improving energy absorption efficiency by 30%;
The fan-shaped design conforms to the dock corners, providing comprehensive protection;
The rectangular design is used around mooring piles to effectively disperse localized pressure.
Combined with 15 specifications of high-strength bolt accessories, it enables precise, customized solutions for different types of ports, including deep-water ports, inland river ports, container terminals, and bulk cargo hubs.
Compared to concrete anti-collision barriers, Port Polyurethane Fenders weigh only one-sixth as much and can be handled by a single person. A team of two can install 40 meters of protective barrier per day, increasing installation efficiency by 60% compared to traditional fenders. Therefore, the lightweight design significantly improves convenience in practical use.
At the same time, the fenders feature a modular splicing and quick-release design. When localized wear occurs, there's no need to remove the entire module; only the damaged module needs to be replaced. This reduces maintenance time from 2 days to 4 hours.
With the help of specialized inspection tools, routine checks only require inspecting surface wear and fixing bolts, eliminating the need for complex professional knowledge. Port operation and maintenance teams can perform these checks themselves.
As a high-tech enterprise in the field of port protection, Aorunda's products strictly comply with EN14308 CE (EU market access), ISO 17357:2002 international standards, and GB/T 21537 domestic specifications, and have obtained dual certification from China Classification Society (CCS) and American Bureau of Shipping (ABS).
During the production process, we use finite element analysis (FEA) to simulate stress distribution under 100 different impact angles and optimize the structural design; each batch of products must undergo 800,000 dynamic compression cycle tests to ensure that no cracking or deformation occurs under high-frequency impact.
Our products have been used frequently for three years in a deep-water port in China, with an average of more than 15 ships docking every day. To date, the fenders have not shown any structural damage, and their performance remains consistently stable and reliable.
Nowadays, ports worldwide are actively building green ports. Our polyurethane fenders meet environmental requirements throughout their entire lifecycle, from production to use: there are no volatile organic compound (VOC) emissions during production, the materials are 100% recyclable, and they do not pollute the marine environment. The fenders have a smooth, burr-free surface, which not only prevents scratching the ship's hull coating but also reduces noise during docking, with an actual noise reduction of 15-20 decibels.
More importantly, their long service life of 12-15 years eliminates the need for frequent replacement, thus reducing waste generation.
After 15 years of relentless effort, Aorunda has participated in numerous port projects along the Belt and Road Initiative, with its products perfectly matching the core requirements of port fendering: safety first, efficiency paramount.
Every Port Polyurethane Fender undergoes rigorous environmental testing and real-world operational verification, backed by data and reputation. Choosing Aorunda means choosing a port fendering solution that ensures heavy-duty performance without damage, requires minimal maintenance even with high-frequency use, and remains reliable in extreme environments. This guarantees smooth and worry-free berthing for large vessels every time, making port operations more efficient and economical.
