1. Pneumatic rubber fender introduction

 

Progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures.

 

Floating pneumatic fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships.

 

Since its creation until today, Henger more than 10,000 fenders have been supplied worldwide both for ship-to-ship and ship-to-dock operations serving our valuable customers.These fenders play a critical role in the safe operation of ship berthing and mooring.

♦ Definition:

The pneumatic rubber fender uses compressed air as the buffer medium, which makes the ship have better anti-collision effect when it is near the ship or dock.

♦ Characteristic:

● External wear resistance

● Bearing pressure

● Ageing resistance

● Long service life

● Good air tightness

● Easy storage

● Non deformation

● Simple installation

♦ Functions & Applications

● Installed on the wharf and dock for berthing

● Installed on the shipboard for berthing

● Float chamber

● For moving the cargo

● Pipe seal

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

 

4. Pneumatic rubber fender introduction

 

Pneumatic rubber fender is one kind of ship berthing, cushioning and protection equipment, which uses compressed air as the buffer medium to prevent collision when the ship is berthing. The pneumatic rubber fender is more economical and durable than the ordinary rubber fender, so it is more popular and widely used.

Pneumatic Rubber Fender is a leading anti-collision device for marine application in the world today and has become an idea ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbors and wharves.

1 Outer rubber

The outer rubber layers that covers the outside of fender protects the cord layers and the inner rubber from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black, but other colors are available on request.

 

2 Inner rubber

The liner of a rubber membrane seals the pressurized air inside the fenders.

 

 

3 Synthetic tire cord layers for reinforcement

The reinforcement layers, which are made of synthetic tire cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.

 

4 Beading ring

A steel ring is placed at one end (or both ends) of the fender and holds the end of cord layers.

 

5 Flange

A steel flange is mounted on the fender, to which an air valve or safety valve can be adapted.

 

6 Safety valve

Fenders of diameter 2500mm and larger shall be equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. Fender which are smaller than 2500mm in diameter, can be equipped with a safety valve if required.

 

7 Metal accessories

All the relevant metal accessories of pneumatic fenders, include shackles, towing rings, swivels, chain net, are made of stainless steel, which are resistant for sea water corrosion.
