Yokohama Fender
Durable Ship Protection Compliant with ISO 17357 Standards
Henger’s yokohama fender is a top-notch ship protection device. It uses air to absorb lots of energy, protecting the ship. Yokohama Rubber Company made it first in 1958.
Since then, it’s been used all over the world for its quality and performance. It’s great for ship-to-ship operations and ports. The fenders are made of high-quality rubber.
They can handle extreme weather and keep ships safe. We offer Yokohama fenders in many sizes and types. All our pneumatic fenders meet ISO17357-1:2014 standards.
Yokohama Fender Construction
Henger’s Yokohama Pneumatic Fenders are built with advanced technology. They are designed for ship protection. Here are their main features and benefits. The following are its main structures:
External rubber layer: The outer rubber layer protects the inner rubber. It also reduces wear and tear on the fender.
Internal rubber layer: The inner rubber keeps air pressure inside. It prevents gas from leaking out.
Reinforcement: The fender’s frame is made of rubber-impregnated cord fabric. This adds strength and durability.
End Tow Rings: Metal parts at the ends hold the cord fabric in place. This makes moving and fixing the fender easier.
Fittings: The fender has inflation ports at one or both ends. These ports allow for quick inflation and deflation. Fenders over 2 meters long have safety valves for added safety.
Yokohama Fenders Advantage
Henger’s Yokohama fenders are extremely durable and are manufactured to ISO 17357 standards.
Yokohama pneumatic fenders can absorb a large amount of impact energy, reducing the impact force on the ship and providing better protection.
while absorbing impact energy, they have a relatively low reaction force, causing less stress and damage to the ship in contact.
these fenders are easy to install, and the mooring ropes or chains attached at both ends can be quickly deployed to the location where protection is needed, improving the efficiency of use.
The fenders can be re-gassed and easily moved according to the location and area of use.
Henger Yokohama pneumatic fenders are lighter than other types of fenders, making them easier to handle and store.
Considering its durability and low maintenance requirements, the Yokohama Pneumatic Fender offers a cost-effective solution for ship protection
Yokohama Fender Performance
The performance of Henger Yokohama pneumatic fenders is measured in several ways. These include impact energy absorption, reaction force, and pressure on the hull. Performance varies with internal air pressure (50kPa and 80kPa). Here is some data on different fender sizes at different air pressures:
- 1000×1500 mm fenders absorb 32kNm of energy and have a reaction force of 182kN at 50kPa. At 80kPa, they absorb 45kNm and have a reaction force of 239kN.
- 2000×3500 mm fenders absorb 308kNm of energy and have a reaction force of 875kN at 50kPa. At 80kPa, they absorb 430kNm and have a reaction force of 1150kN.
- 3300×6500 mm fenders absorb 1814kNm of energy and have a reaction force of 3015kN at 50kPa. At 80kPa, they absorb 2532kNm and have a reaction force of 3961kN.

Yokohama Rubber Fender Size
Choosing the right size Yokohama Pneumatic Fender depends on the vessel’s type and size. Also, think about where and how you’ll use it. Here are some tips for picking the right fender for different vessels:
Small to medium-sized vessels: like fishing boats and tugboats, need smaller fenders. Sizes range from 0.5×1.0m to 1.5×3.0m, based on the ship’s size and how it’s used.
Large ships: like carriers and tankers, need bigger fenders. Sizes like 3.0×5.0 m or 3.3×6.5 m are chosen for their safety and energy absorption.
For example, a 2.0×4.0m fender might be good for a 10,000 DWT carrier. But, a 3.3×6.5m or bigger fender is needed for a 200,000-ton tanker for safety.
