It can cope with various extreme environmental conditions and effectively ensure the safety of ship operation. We can provide Yokohama fenders in a wide range of sizes and performance according to different needs, and we guarantee that all pneumatic fenders manufactured by Henger comply with ISO17357-1:2014.

Yokohama Fender Construction

The construction and advantages of Henger’s Yokohama Pneumatic Fenders reflect its advanced technology and wide range of applications in the field of ship protection. Below are its main features and advantages

External rubber layer: The rubber layer on the outside of the fender protects the rubber structure inside the fender and minimizes wear and tear on the fender.

Internal rubber layer: The rubber layer inside the fender maintains air pressure inside the fender and prevents gas leakage.

Reinforcement: Rubber-impregnated cord fabric forms the frame material of the fender body, adding strength and durability.

End Tow Rings: The ends of the fender are fitted with metal parts to hold the cord fabric ends in place, facilitating the movement and fixation of the fender.

Fittings: One or both ends of the fender are equipped with inflation ports for quick inflation and deflation of the fender. Fenders over 2 meters direct will be equipped with safety valves to improve the safety index of the fender during its use.

Yokohama Rubber Fender Advantage

Henger’s Yokohama fenders are extremely durable and are manufactured to ISO 17357 standards.

High energy absorption

Yokohama pneumatic fenders can absorb a large amount of impact energy, reducing the impact force on the ship and providing better protection.

Low reaction force

while absorbing impact energy, they have a relatively low reaction force, causing less stress and damage to the ship in contact.

Easy to install

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.

Flexibility

The fenders can be re-gassed and easily moved according to the location and area of use.

Lightweight

Henger Yokohama pneumatic fenders are lighter than other types of fenders, making them easier to handle and store.

Affordability

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 can be measured by their absorption of impact energy, reaction force, and pressure on the hull, and these performance indicators will vary at different internal air pressures (50kPa and 80kPa). Below are some example data showing the performance of different fender sizes at different air pressures:

  • 1000×1500 mm fenders have an energy absorption of 32kNm a reaction force of 182kN at 50kPa and 45kNm and a reaction force of 239kN at 80kPa.
  • 2000×3500 mm fenders have an energy absorption of 308kNm a reaction force of 875kN at 50kPa and 430kNm and a reaction force of 1150kN at 80kPa.
  • 3300×6500 mm fenders have an energy absorption of 1814kNm and a reaction force of 3015kN at 50kPa, an energy absorption of 2532kNm, and a reaction force of 3961kN at 80kPa.

Yokohama Rubber Fender Size

When choosing the right size Yokohama Pneumatic Fender, consider the type and size of the vessel as well as the intended use scenario. Below are some suggestions for selecting fenders for different sizes and types of vessels:

Small to medium-sized vessels: such as fishing vessels, tugboats, etc., can choose fenders in smaller sizes, for example, in the range of 0.5×1.0m, 0.7×1.5m to 1.5×3.0m, depending on the ship’s tonnage and operating conditions.

Large ships: including carriers, tankers, etc. Depending on the ship’s DWT (deadweight tonnage) and expected landing speed, larger fenders, such as 3.0×5.0 m, 3.3×6.5 m, or larger, are selected to ensure adequate energy absorption and safety margins.

For example, a 2.0×4.0m fender may be considered for a 10,000 DWT carrier, while a 3.3×6.5m or larger fender may be required for a large tanker with a DWT of 200,000 tons to meet safety requirements.
