pneumatic fender types
Have you ever heard of pneumatic rubber fender or yokohama fender. To be honest, they're actually same produce and we have other names for them, For example yokohama rubber fender , floating pneumatic rubber fender, we can simply call it yokohama fender or pneumatic fender.Have you ever heard of pneumatic rubber fender or yokohama fender. To be honest, they're actually same produce and we have other names for them, For example yokohama rubber fender , floating pneumatic rubber fender, we can simply call it yokohama fender or pneumatic fender. Why is it called yokohama fender? Because it was originally invented in 1985 by a rubber products company in Yokohama, Japan, and they developed a set of testing standards for the industry. All products sold by experts were required to conform to this standard (ISO17357). This minimum standard pneumatic fender was later called yokohama fender. If you want to know about the history of yokohama, you can click here. Of course, at present, the pneumatic fender sold by NANHAI company far exceeds the standard of ISO17357, and even the performance is 60% of that of ISO17357 pneumatic fender. This video is a use of our real scenario.
The interior of the pnumatic fender is filled with high-pressure air. And it is easily deflated so that it can be easily relocated and debugged. Pneumatic fenders are used to absorb kinetic energy from a dock, dock wall or dock. Fenders can be applied to all types of vessels, from cargo ships to cruise ships, ferries and private yachts, and can prevent damage to ships and berthing structures.
Next, we will give you a brief introduction to the different types of pnuematic fender should be used in what place, so that you can choose according to the specific situation. At present, all kinds of pneumatic fender provided by NANHAI Company are basically all types of pneumatic fender in the industry, and we also customize different types of pneumatic fender for customers, including color, size, specifications and other aspects. We will highlight the four popular pneumatic fender types on the market: sling pneimatic fender, ribbed pneumatic fender, net tire pneumatic fender and Hydro pnuematic fender. The first three of its use is basically the same, but the style is different, the following is their picture show.
The use scenario of the first three types of pneumatic fender is basically the same, but because of the difference in performance, if your ship or dock is not very large, Consider sling pneumatic fender or Ribbed pneumatic fender, but if you have a large dock or ship, or a cargo ship, Or for engineering, you are recommended to use Net tire pneumatic fender. and hydro pneumatic fender is used in deep draft docks or luxury yachts, submarines and other directions. Of course, if you have sufficient funds, you can use this product in other scenarios, but in comparison, it is more recommended to use the pneumatic fender with the sheath of aircraft tires. Below are some of their respective introductions, so that you can better understand the type of pneumatic rubber fender.

Pneumatic fender sizes
Pneumatic fenders are crucial for safe ship-to-ship and ship-to-dock operations, and their sizes are determined based on the requirements of the ships and the type of operation. The ISO 17357 standard outlines the standard sizes of pneumatic fenders, but customization is often needed for specific applications. At present, NANHAI has taken over the 20-year experience list. Among all the lists, there are few ISO17357 standard sizes used, and most of the time, the company will customize the pneumatic fender according to the size of the ship and dock by our professional designers, and this is a free consultation in NANHAI.
Standard Sizes
The ISO 17357 standard provides a range of standard sizes for pneumatic fenders, combining 12 diameter sizes and 13 length sizes. This results in 17 standard sizes, each designed to accommodate different ship sizes and operational requirements.
Diameter and Length Ranges
Diameter Range: 0.5 m to 4.5 m
Length Range: 1 m to 12 m
Common Sizes for Ship-to-Ship Operations
3.3 m x 6.5 m: Suitable for larger vessels, providing substantial cushioning and protection during ship-to-ship transfers.
2 m x 3.5 m: More appropriate for smaller vessels or operations where space and maneuverability are factors.
Custom Sizes
While standard sizes are widely used, many manufacturers offer customization for non-standard sizes to meet specific operational or environmental conditions. Custom pneumatic fenders are tailored to fit unique ship sizes, docking configurations, or specific safety requirements.
Selecting the Right Size
When determining the appropriate pneumatic fender size for a particular ship or operation, consider:
Ship Size and Type: Larger vessels require bigger fenders to absorb more energy.
Operational Environment: Factors like water depth, dock size, and environmental conditions.
Safety Margins: Ensuring the fender can handle the impact forces expected in its operational scenario.

Pneumatic fender uses
Pneumatic fenders are crucial for preventing collisions between ships and effectively reducing berthing energy, thus avoiding permanent damage to both the hull and the dock's concrete structure. Yokohama fenders are especially well-suited for various maritime operations, including short-term port visits, cargo transfers, buoyancy assistance, and double berthing scenarios. They are typically installed using chains and shackles on pre-installed dock bases, allowing them to float horizontally and adapt to changing water levels due to tides.
In addition to protecting docks, Yokohama pneumatic fenders can be mounted on the sides of vessels to prevent collisions during sea docking operations. This is particularly important in ship-to-ship (STS) operations, which are common during the transfer of liquid cargo at sea. Pneumatic fenders also play a vital role in double berthing operations, where one ship is moored at a port while another docks alongside it. This setup facilitates quick and efficient cargo transfers, enhancing terminal efficiency.
Furthermore, pneumatic fenders can temporarily provide buoyancy to a vessel, helping to prevent grounding in shallow waters. This additional function ensures that vessels can navigate safely even in areas with limited depth.
Then we will give a specific application scenario of pneumatic fender to help you better understand the product, so as to help you make a judgment when choosing

Production Methods and Their Impact on Cost
Pneumatic fenders are primarily manufactured using two methods: the mold type and the winding type.
-
Mold Type: Molded pneumatic fenders are produced in a single, continuous piece, without any connection points. This method results in a more seamless and robust fender. The molding process generally requires higher initial investment due to the cost of manufacturing molds. Consequently, the price of molded fenders tends to be higher.
-
Winding Type: Winding type fenders are constructed by manually layering rubber sheets around a core. This method does not require molds, which helps reduce production costs. As a result, fenders produced using this technique are usually more affordable. However, they may have different performance characteristics compared to molded fenders.
Material Quality and Its Effect on Pricing
The rubber material used in pneumatic fenders must meet specific purity standards. High-quality rubber should have minimal impurities. Some manufacturers may choose lower-quality rubber with higher impurity levels to cut costs, leading to cheaper prices. This practice can compromise the durability and safety of the fenders.
When comparing prices, if you find significant price discrepancies between different suppliers, it's important to consider the quality of the materials used. Lower prices may indicate the use of inferior materials or less rigorous production processes.
Why Quality Matters
