Premium Yokohama Pneumatic Fenders - Your Reliable Choice for
Marine Impact Protection
What is a Yokohama Pneumatic Fender?
A Yokohama pneumatic fender is a type of marine fender that uses
compressed air to provide cushioning and energy absorption. It
consists of a durable outer rubber or synthetic material cover that
encloses an air - filled chamber. When a vessel comes into contact
with a dock or another structure, the fender compresses, absorbing
the impact energy and reducing the force transferred to both the
vessel and the structure.
Features
1. Soft Reaction Force for Ship and Jetty Structure
Although all fenders should be used within their maximum load
limit, it often happens that fenders accidentally receive excess
load. The reaction force of Yokohama Pneumatic Rubber Fenders does
not increase sharply, even under excess load conditions. Therefore,
the Yokohama Pneumatic Rubber Fenders perform well in such cases,
and protect ships and mooring facilities. In contrast, the reaction
force of solid rubber fenders, including buckling-type fenders,
increases sharply under excess load conditions. The excess load
turns the solid-type fender into a solid rubber block, which cannot
perform as a fender. This often leads to damage of the ship and
mooring facilities.
2. Advantages at Inclined Berthing
Ships usually make initial contact with the dock or another ship on
STS operations at an oblique angle. In the case of solid rubber
fenders or foam fenders, rated reaction force and energy absorption
decreases considerably at inclined compressions compared with
parallel compression. In order to compensate for the decrease of
energy absorption at inclined compression, it is necessary to use
larger sizes in the case of solid rubber fenders or foam fenders.
Distribution of load is also comparatively even because of the
molecular freedom of air and high flexibility of the multi-layered
cord-reinforced rubber membrane. This makes the body of a pneumatic
rubber fender more shape conformant compared to solid or foam
fenders, and thus able to better distribute the load along the hull
of a ship or jetty structure during inclined compression.
3. High Energy Absorption
Yokohama pneumatic fenders are engineered to have excellent energy
absorption capabilities. The air - filled design allows them to
deform under impact, effectively dissipating a large amount of
kinetic energy. This helps to minimize damage to the vessel's hull
and the dock, reducing repair costs and downtime. For example,
during the berthing of large container ships, which can generate
significant impact forces, these fenders can absorb the shock and
prevent serious structural damage.
4.Durability
The materials used in Yokohama pneumatic fenders are of high
quality. The outer cover is typically made of robust rubber
compounds that are resistant to abrasion, UV radiation, and the
corrosive effects of seawater. This ensures a long service life,
even in harsh marine environments. The air - tight construction
also helps to maintain the integrity of the fender over time,
reducing the need for frequent replacements.
5.Customizable Design
Yokohama offers a range of pneumatic fenders with customizable
designs to meet the specific requirements of different marine
applications. Fenders can be manufactured in various shapes, sizes,
and configurations to fit different vessel types, dock layouts, and
operational needs. Whether it's a small coastal vessel or a large
oil tanker, there is a Yokohama pneumatic fender solution
available.
6.Stable Performance
These fenders provide stable performance under a wide range of
operating conditions. The air pressure inside the fender can be
adjusted to optimize its performance for different vessel sizes and
berthing speeds. This adaptability ensures consistent energy
absorption and protection, regardless of the specific circumstances
of the berthing operation.
Applications
1. Ports and Docks
Berthing of Large Vessels: In major international ports handling
container ships, bulk carriers, and tankers, Yokohama pneumatic
fenders are installed on dock walls. They absorb the significant
impact energy during berthing, protecting the vessel's hull from
scratches, dents, and structural damage, as well as safeguarding
the dock infrastructure.
Mooring of Small Craft: In marinas and small ports, these fenders
are used for fishing boats, yachts, and coastal ferries. They act
as a cushion during mooring, preventing damage to the smaller
vessels and the mooring facilities.
2. Offshore Installations
Platform Berthing: For offshore oil and gas platforms, Yokohama
pneumatic fenders are crucial when supply vessels or service boats
berth. They protect the platform's structure and the vessels from
the impact caused by waves and vessel movement in the dynamic
offshore environment.
FPSO (Floating, Production, Storage, and Offloading) Units: These
units often require fenders to protect against collisions with
other vessels during operations such as loading and unloading of
crude oil. The pneumatic fenders help maintain the integrity of the
FPSO and the connected vessels.
3. Ship - to - Ship Operations
Transfer Operations: During ship - to - ship transfer of cargo,
such as in the case of bunkering (refueling of one ship from
another) or transfer of liquid chemicals, Yokohama pneumatic
fenders are used to keep the vessels at a safe distance and cushion
any potential impacts. This ensures the safety of the transfer
operation and prevents damage to both ships involved.
4. Bridge Piers and Marine Structures
Bridge Protection: Pneumatic fenders are installed around bridge
piers in waterways to protect them from collisions by passing
vessels. They absorb the impact energy, reducing the risk of damage
to the bridge structure, which could have serious consequences for
transportation and safety.
Marine Breakwaters and Jetties: These structures can be protected
from the impact of waves and vessels using Yokohama pneumatic
fenders. The fenders help maintain the integrity of the breakwaters
and jetties, ensuring their long - term functionality in protecting
the shoreline and port facilities.
ISO17357-1 : 2014 : Certified
COMPLIANCE WITH ISO17357-1:2014
The new ISO standard for the high pressure pneumatic fender was
published in 2014. ISO17357-1:2014 “Ships and marine technology -
Floating pneumatic rubber fenders - Part 1: High pressure”, which
supersedes the former standard published in 2002, has set the new
requirements with respect to design, material and the mandatory
performance testing to enhance product reliability. As an industry
leader of the pneumatic fenders, Yokohama has contributed in
establishing a new standard by providing technical expertise
derived from our long years of experience.
Needless to say, all Yokohama fenders are in full compliance with
ISO17357-1:2014.
