Hydro Submarine Fender
Hydro submarine fender is installed vertically with water and air pressurized inside. It's widely used in the applications of submarines and other ships' contact fenders below the waterline.
Jerryborg Hydro submarine fenders are popular cause of their excellent performance of low reaction force and high energy absorption capacity. Furthermore, their performance is affected by the ship hull shape, gas mixture, initial pressure, and water to air ratio. And you can adjust the performance by changing the water to air ratio and initial pressure.
Hydro submarine fenders are made of natural rubber and tire cord reinforcement in the shape of cylindrical, which is strong enough to withstand external forces and severe weather conditions.
Hydro Submarine Fender Structure
① Outer rubber layer
The outer rubber layer uses special compounds that provide additional tensile strength and tear strength to protect the fender from severe weather conditions and frequent use.
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.
Hydro Submarine Fender Advantage
1. absorb more energy and reduce the adverse impact on the ship
2. safely overload
3. portable and easy installation
4. a long lifespan
5. various sizes can be customized upon the customer's requirements
