Floating Pneumatic Fenders for Ship-to-Ship Operations

Floating pneumatic fenders—also known as Yokohama fenders—are essential for ensuring safety and efficiency in ship-to-ship (STS) operations. These inflatable marine fenders act as protective buffers between vessels, absorbing impact energy and preventing damage during berthing and cargo transfers. Their versatility and reliability make them a preferred choice for various maritime applications.

Why Are Floating Pneumatic Fenders Necessary?

Imagine two massive vessels, such as LNG carriers or oil tankers, conducting a ship-to-ship transfer in open waters. Without proper cushioning, even minor contact could cause serious structural damage, environmental risks, or costly delays.

Floating pneumatic fenders offer a flexible and reliable solution. They adjust to tidal changes and vessel movement to keep a safe distance and absorb impact energy.

These fenders can fit different hull shapes and perform well under various conditions. This makes them essential for modern maritime operations.

What Are Floating Pneumatic Fenders?

Floating pneumatic fenders are cylindrical, air-filled devices made from synthetic-cord-reinforced rubber. They float on the water’s surface and serve as shock absorbers during vessel interactions. Common types include:

• Chain & Tire Net Type: Encased in a protective net of chains and tires, offering enhanced durability.
• Sling Type: Simpler design without external nets, suitable for various applications.

These fenders are compliant with ISO 17357 standards, ensuring quality and performance in demanding maritime environments. The pneumatic fenders made by Nanhai not only meet but actually surpass the ISO17357 standard, offering enhanced performance and a longer lifespan.

Key Advantages of Pneumatic Fenders in STS Operations

• High Energy Absorption: Pneumatic fenders can absorb significant amounts of kinetic energy, reducing the impact force between vessels.
• Low Reaction Force: They exert minimal pressure on the hull, preserving the structural integrity of the ships involved.
• Adaptability: Their buoyant nature allows them to adjust to varying tidal conditions and vessel movements, maintaining optimal positioning during operations.
• Ease of Installation: Lightweight and easy to deploy, pneumatic fenders can be quickly positioned between vessels, facilitating prompt commencement of STS operations.
• Durability: Constructed from robust materials, these fenders are designed to withstand harsh marine environments and have a service life of up to 10-15 years.

In STS operations, 3 to 5 main fenders and 2 to 3 secondary fenders are usually placed between the two ships. This setup creates a stable buffer zone.

The fenders are tied with mooring ropes to the mooring bollards on the main deck. This helps them stay in the correct position during the operation.

Overall, pneumatic fenders are indispensable in STS operations, providing a reliable and efficient means to protect vessels and ensure smooth cargo transfers at sea.

Choosing the Right Fender for Your Needs

Selecting the appropriate floating pneumatic fender involves considering factors such as vessel size, operating environment, and specific application requirements. Consulting with experienced marine equipment suppliers can help determine the optimal fender type and configuration to ensure safety and efficiency in your operations.

What is the lifespan of a floating pneumatic fender?

With proper maintenance, these fenders can last 10 to 15 years, depending on usage and environmental conditions.

How do pneumatic fenders differ from foam-filled fenders?

Pneumatic fenders use compressed air for energy absorption, offering flexibility and adaptability, while foam-filled fenders have a solid core, providing consistent performance with less maintenance.

Are floating pneumatic fenders suitable for all vessel types?

Yes, they are versatile and can be used for various vessels, including tankers, cargo ships, and naval vessels, in both STS and ship-to-dock operations.

Investing in high-quality floating pneumatic fenders is crucial for the safety and efficiency of ship-to-ship operations. Their proven performance, adaptability, and compliance with international standards make them an indispensable component in modern maritime activities.
