When a big ship docks, it can cause a lot of damage. Marine operators need a way to prevent this. Pneumatic fenders are the answer.
Henger Shipping Supplies, a top Chinese marine equipment maker, focuses on quality. We make Yokohama fenders and marine rubber fenders. We know how important protection is at sea.
Pneumatic fenders soak up the energy when a ship docks. This reduces the impact and damage. Yokohama Rubber Company invented them in 1958. Now, they’re a key part of maritime safety.
We’ll look at how these devices work, their benefits, and why they’re vital for safety at sea.

What are Yokohama Pneumatische Fender?
Pneumatic fenders also become Yokohama fenders, which are inflatable rubber devices. They’re made to handle the energy from docking and mooring. They protect ships from damage during these operations.
Was sind pneumatische Fender?
Pneumatic fenders are inflatable rubber devices. They’re key to keeping ships safe in the water. They’re more effective than other fenders in many situations.
Komponenten und Konstruktion
Pneumatic fenders have three parts: an outer rubber layer, a tire cord layer, and an inner air bladder. The outer layer is tough, and the tire cord layer adds strength. Our fenders meet ISO 9001-2008 standards for quality.
Choosing the right materials is crucial. The layers are bonded for durability. We offer different sizes and types to fit various ships and docking needs.
How Pneumatic Fenders Work
Pneumatic fenders work by compressing and absorbing energy when hit. This makes docking safer. We’ll explain how they do this and how they’re set up.
Energy Absorption Mechanism
Pneumatic fenders work by compressing air when hit. This cushions the impact and lessens the force on the ship and dock. There are two main steps: absorbing and dissipating energy.
- Energy absorption happens when the fender compresses on impact, taking in the ship’s energy.
- Energy dissipation occurs as the air inside the fender spreads out the absorbed energy, reducing the impact on the ship and dock.
The air inside the fenders makes them flexible yet strong. This lets them handle big impacts while keeping their shape.
| Stage | Beschreibung | Effect |
| Energie-Absorption | Pneumatic fender compresses upon collision | Absorbs kinetic energy |
| Energy Dissipation | Compressed air dissipates absorbed energy | Reduces impact on the vessel and the dock |
Deployment and Installation Process
Installing pneumatic fenders involves several steps. These include inflating them, checking the pressure, and placing them correctly. Doing this well ensures they work best in different situations at sea.
We’ll cover the best ways to inflate and check the pressure. Where you put the fenders is also key. It affects how well they absorb impacts.
Knowing how pneumatic fenders work helps operators protect their ships and docks. They’re a vital safety tool at sea.
Comparing Pneumatic Fenders to Other Types
It’s important to compare pneumatic fenders with other types to understand their strengths and weaknesses. Pneumatic fenders are popular in the maritime world because of their special features. But how do they compare to other fender types?
Pneumatic vs. Foam-Filled Fenders
Pneumatic fenders and foam-filled fenders are both common in the maritime field. They both help absorb energy and lessen the impact of collisions. But they differ in how they are made and how they work.
Foam-filled fenders don’t leak air when they get a hole, but they don’t absorb energy as well after getting damaged. Pneumatic fenders, on the other hand, lose their function if they get a hole. But the air inside helps spread out the impact forces more evenly.
| Fender Type | Energie-Absorption | Dauerhaftigkeit | Performance After Damage |
| Pneumatische Fender | High initial energy absorption | Dependent on outer rubber integrity | Loses function if punctured |
| Foam-Filled Fenders | Absorbs 40% more energy than pneumatic fenders (according to some reports) | More resistant to punctures | Reduced energy absorption efficiency after damage |
Durability and Performance Differences
The durability and performance of pneumatic fenders compared to foam-filled fenders are key. Pneumatic fenders absorb energy well but rely on their outer rubber layer’s integrity.
Foam-filled fenders, however, still work somewhat after getting damaged, even if not as well. The choice between pneumatic and foam-filled fenders depends on the vessel’s needs and the operational conditions.
Anwendungen von pneumatischen Fender
We look at the many uses of pneumatic fenders in maritime safety. They protect vessels and structures in various maritime operations.
Ship-to-Ship Transfers
Pneumatic fenders are crucial in Schiff-zu-Schiff-Transfers. They protect during cargo and liquid transfers between ships. Their ability to absorb energy and low reaction forces makes them perfect for this.
Schiff-zu-Terminal-Operationen
In ship-to-terminal operations, pneumatic fenders protect ships when docking at ports and terminals. They can be adjusted for different tides, ensuring safety for vessels and structures.
Offshore-Plattformen und Marineoperationen
Pneumatic fenders are also used in offshore and naval operations. They provide strong impact protection for platforms, vessels, and submarines. Their flexibility makes them suitable for many environments and needs.
Maintenance and Longevity of Pneumatic Fenders
Pneumatic fenders need little Wartung, but regular checks are key to their long life. Both pneumatic and foam-filled fenders require minimal care. Yet, pneumatic fenders need air added about once a year to work well.
On the other hand, foam-filled fenders don’t need air, giving them a slight edge in maintenance. However, pneumatic fenders are easy to move without air, saving space. For storage, filling them partially with air is best to keep the rubber in good shape.
With the right care, pneumatic fenders can last 8 to 10 years. We stress the need for regular checks and proper inflation. Following these steps helps extend their life, making them a solid choice for marine use.
FAQ
What is the primary function of a pneumatic fender’s outer layer?
The outer layer, made of tough rubber, protects against impacts and abrasions. It also helps spread out the force of impacts.
How do pneumatic fenders absorb energy during berthing or mooring operations?
Pneumatic fenders soak up energy by compressing air inside. This reduces the impact force, protecting ships and structures.
What are the key differences between pneumatic fenders and foam-filled fenders in terms of performance?
Pneumatic fenders are better at absorbing energy and managing impact forces than foam-filled fenders. They’re often the first choice for tough applications.
How often should pneumatic fenders be inspected and maintained to ensure optimal performance?
It’s important to check and maintain pneumatic fenders regularly. Look for wear, damage, or air leaks. Do routine maintenance as needed.
Can pneumatic fenders be used in various marine environments, such as offshore platforms and naval operations?
Yes, pneumatic fenders are versatile. They’re great for ship-to-ship transfers, terminal operations, and offshore use. They’re good at absorbing energy and reducing impact forces.
What factors should be considered when selecting a pneumatic fender for a specific application?
When picking a pneumatic fender, think about the vessel size and type, mooring conditions, and energy absorption needs. Also, consider the required impact force management.
