SA-A-Type Rubber Fenders for Vessel-to-Berth Impact Protection

The SA-type super arch rubber fender is one of the most widely used fender types today. It features high energy absorption, flexible installation, and optimal design dimensions, making it an ideal choice for protecting ports and vessels. Compared to other fender types, SA fenders excel in energy absorption efficiency relative to material consumption, achieving both high performance and cost-effectiveness.

Product Features

1.High Energy Absorption
SA-type rubber fenders offer superior energy absorption per unit weight. They outperform cylindrical fenders by 3.5 times and D-type fenders by 2.3 times, making them highly efficient in protecting port and vessel structures.
2.Optimized Compression Design
With improved compression deformation, the SA fender increases energy absorption by 20% compared to V-type fenders and 8% compared to M-type fenders.
3.Excellent Anchoring Performance
SA fenders are suitable for a variety of applications, including ships, docks, and shipyards, providing a wide range of protection.
4.Front Panel with PE Facing Pads
Equipped with a front panel and PE pads, the SA fender reduces surface pressure and friction with vessel hulls, minimizing shear forces during berthing.
5.Adaptability to Irregular Vessel Hulls
Designed to accommodate uneven hull surfaces (e.g., small vessels or those with protrusions), the SA fender reduces friction and shear forces, ensuring safer berthing operations.
6.Wide Application Range
Suitable for container terminals, liquid cargo berths, bulk cargo docks, and inland waterways, SA fenders provide versatile protection for various scenarios.

Considerations

While SA-type fenders are highly efficient, they may exert higher pressure on low-strength vessel hulls (e.g., oil tankers). Selection should be tailored to specific vessel types.

Advantages

● Ports and Docks: Ideal for various berth types, offering efficient protection.
● Ship Berthing: Safeguards vessel hulls and dock facilities, reducing impact risks.
● Offshore Platforms: Serves as a buffer device to prevent damage from vessel collisions or wave impacts.
● Inland Waterways: Meets protection needs for river transportation terminals.
● Bridge Pier Protection: Provides additional protection in bridge and other specific scenarios.

Manufacturing Standards

The product is designed and manufactured in strict accordance with the latest effective specifications of the classification society at the time of contract signing to ensure that the product quality meets industry standards.

FAQ

1. The SA-A type fender looks relatively simple in structure. What are its main advantages compared to more complex fenders?

Answer: You've made a good observation. The SA-A type utilizes a classic single-arch structural design, which is its core strength. Simple structure means high reliability and fewer potential failure points. It has been proven over decades of port operations with stable performance. Compared to more complex fenders, its main advantages are:
1.High Cost-Effectiveness: More competitive manufacturing costs, offering you an economical and reliable dock protection solution.
2. Easy Installation & Maintenance: The intuitive structure makes both installation and subsequent inspection very straightforward, reducing labor and time costs.
3. Wide Applicability: It provides effective protection for most inland river ports, small to medium-sized seaport berths, and the berthing needs of general cargo ships and Ro-Ro vessels.
2. If damaged by a ship, are the repair or replacement costs high?

Another advantage of the SA-A type is its relatively low maintenance cost. Due to its classic structure and high standardization, the cost of purchasing spare units is controllable. For local wear or minor cuts, economical and convenient on-site patching is possible. Even if a full unit replacement is needed, the standardized installation allows for quick replacement of a single fender unit, minimizing impact on berth operations.
3. In ports that freeze in winter, will it get frozen stuck?

For ports with freezing periods, we have corresponding solutions. We can provide SA-A type fenders with a low-temperature resistant compound that maintains good elasticity in cold weather to avoid brittleness. Additionally, the arch-shaped surface helps ice sheets break away during temperature changes or vessel contact, preventing large-scale ice adhesion.
4. Our dock might be upgraded in the future to accommodate larger ships. Will installing SA-A types now make them obsolete quickly?

Forward-thinking in dock planning is wise. Today's choice doesn't have to lock in the future. The modular arrangement feature of SA-A type fenders actually offers flexibility. If the berth is upgraded later, you can enhance overall protection by "increasing the number of fenders" or "replacing them with larger specifications." At that time, some existing fenders might still be used in secondary positions or as spares, avoiding complete resource waste.
