Description

US navy yokohama electric submarine hydro pneumatic rubber fender

The Hydropneumatic Fender is a special version of the Pneumatic Fender developed for submarines. They are filled with water and air then fitted with a counterweight that holds them upright against submerged hulls, Hydropneumatic Fender are designed to be installed vertically making them ideal for use with submarines or vessels whose impact point is likely to be below the waterline such as Catamarans, Semi-Submersible platforms and Drilling Rigs, protecting submarines and other vessels that make contact below the waterline.

JRB Hydropneumatic Fenders can be performance 'tuned' by varying the initial pressure, water to air ratio and ballast weights to suit the hull curvature and sensitivity of the latest submarines.

The Hydropneumatic fenders can be installed on most Quay structures and come in a range of sizes to suit the application and a range of vessels.

Advantages of JRB pneumatic fenders:

1 Performance can be adjusted by altering the air-water ratio
2 Required draft can be adjusted
3 Low hull pressures
4 Self-adjustment during tidal variation
5 Low installation and maintenance cost

HYDROPNEUMATIC FENDER DRAWING WITH CUSTOMIZED SUBSTRUCTURE

Hydro Pneumatic Fender Structure

1 .Outer rubber layer

Hydro pneumatic fenders are covered by the outer layer made of natural rubber. This rubber compound is strong enough to protect the inner layer and synthetic-cord layer from the damage of external forces and severe weather conditions due to its high elasticity and abrasion resistance.

2. Synthetic-tire-cord layer

The Synthetic-tire-cord layer is made of synthetic-tire-cord fabrics, compared with synthetic canvas fabric and synthetic belt fabric, this reinforcement layer performs better in fatigue-resistance and pressure-holding.

3. Inner rubber layer

The inner rubber layer is designed to seal the air inside the fender.

Safety and Reliability
Yokohama Pneumatic Rubber Fenders are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders.

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.

Adaptable to the Tide
Yokohama Pneumatic Rubber Fenders basically float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement. This means that energy absorption always takes place at the most suitable position, and that only one fender is required per dolphin.

Applications

1. Submarine Jetties
2. Certain Ferry Types
3. Oil Rigs

Shipping Cost Minimization
In order to minimize the shipping cost of Yokohama Pneumatic Rubber Fenders, the fenders are usually packed and shipped in containers or on pallets in vacuumed and folded down state.
