Submarine Fender
Cutting-Edge Design for Optimal Marine Protection
Submarine fenders are another important type of pneumatic rubber fenders that are necessary mooring protection for submarines while docked. As submarines have unique docking requirements below the waterline, the design and function of submarine fenders are critical, and Henger’s pneumatic fenders are designed to effectively prevent collision damage at berth by providing gentle pressure and minimizing hull stress. At the same time, Henger’s technical team has taken into account the dynamic conditions unique to underwater, such as tidal changes and underwater flow, allowing the submarine to ensure reliable protection even in complex marine environments.

Essential Functions of Henger's Submarine Fenders for Safe Docking
Because submarines operate in a different environment than common surface vessels, they often require specialized mooring equipment for docking. A submarine fender is a specialized piece of protective equipment for submarines, which provides the necessary cushioning to protect the submarine from damage during the critical docking phase. Its main functions are as follows:
Preventing damage to acoustic tiles: Submarine fenders are designed to absorb and disperse the forces during docking, minimizing the risk of damage to the acoustic tiles on the hull. This is essential to maintain the submarine’s stealth capability.
Reduces high-pressure structural risk: The engineering behind the submarine fenders focuses on applying minimal pressure to the submarine’s hull, thus preventing high-pressure potential stress points that could lead to structural failure or leakage.
Assures safe docking: Submarine fenders ensure that the submarine can be safely docked in any state of buoyancy by adjusting the variable draft of the submarine.
Types of Submarine Fenders
In the field of marine engineering, a submarine fender is a device specifically designed to protect a submarine during docking. These fenders absorb the kinetic energy of a docked submarine and prevent damage to the vessel and mooring infrastructure. Henger currently offers hydraulic submarine fenders, sand-filled submarine fenders, and customized versions.
Hydraulic Submarine Fenders: Hydraulic fenders are a combination of water and air that absorbs the impact energy of the submarine as it comes into contact with the dock. Hydropneumatic fenders are suitable for all submarine sizes and docking speeds as the level of energy absorption can be maintained by adjusting the height of the waterline inside the fender.
The main advantage is that the fender’s buoyancy and pressure can be adjusted to suit different docking conditions, providing a more flexible solution for docking submarine fenders.
Custom Engineered Systems: Based on the specific requirements of different submarines and docking, Henger’s technical team has developed custom-engineered systems for submarine fenders to meet the specific operating parameters of different submarines. These customized solutions can be combined with hydraulic fenders and other submarine fender innovations from the Henger team, such as integrated monitoring systems for real-time performance feedback and automatic adjustment functions. Qingdao’s customized systems for submarine fenders are ideally suited for submarine-fendered naval bases and commercial terminals, or other submarine docking areas with design features.
Hydrodynamic Fender Features
Submarine fenders are designed and constructed to incorporate a range of features designed to maximize the safety of the submarine’s docking, the following are the main features of submarine fenders:
Adjustable Performance: Submarine fenders can be adjusted to absorb capacity according to the specific parameters of the docked vessel. To meet the docking needs of vessels of different sizes.
Low Installation and Maintenance Costs: A significant advantage of submarine fenders is the relatively low installation and maintenance costs. This economy is realized through durable materials and innovative designs that reduce the need for frequent replacement or repair.
Stability: The hydraulic fender’s water injection provides the fender with the necessary buoyancy, while the counterweight ensures the stability of the fender and the correct positioning of the submarine’s hull.
Installation & Maintenance
Like the pneumatic fenders, the submarine fenders are very easy to install and the team at Henle will provide full guidance during the installation of the submarine fenders as well as a submarine installation brochure for more teams working on submarine fender docking projects.
In terms of maintenance, the material structure of the submarine fenders is made of a combination of natural rubber and high-strength synthetic rubber, which greatly improves the durability of the submarine fenders in long-term contact with seawater. Purchasers of submarine fenders only need to carry out simple and regular maintenance under the guidance of the Henle after-sales team.
