High Pressure Submarine Fender Pneumatic Yokohama Fender For Ship Berthing
The fender is mainly to withstand the impact force of the ship when
the ship is docking, leaving the dock and other forms (such as when
the ship is tied to tow), and transmits it to the hull structure of
a larger area. Wooden fenders have buffering effect. Although steel
fenders have poor buffering effect, they have better strength and
can be included in the section of the hull girder (the welding
strength must be guaranteed). Especially for large-open deck
barges, they can make up for the deck The lack of effective
cross-sectional area is conducive to longitudinal strength. Steel
materials cannot be used for the fenders of oil barges and small
oil tankers.
Large seagoing vessels usually do not have fenders. River boats,
work boats, permanent double-track fenders, one of which is located
on the upper deck, and the other is located slightly higher than
the designed waterline

Pneumatic Rubber Fender Application
1. Oil and gas tankers
2. Fast ferries and aluminum vessels
3. Temporary and permanent installations
4. Rapid response and emergencies
5. In ports with extreme tidal variations
6. For ship-to-ship lightering operations
7. For all navy vessels due to low hull pressure and the advantage
of a proportional increase of reaction force and energy absorption
