Submarine Fenders Reduced Wear And Tear And Compliant With International Maritime Standards
Description
During submarine refits and overhauls, vessels spend extended periods moored at repair yards. Submarine Fenders in this setting must provide continuous hull protection, withstand long-term static loads, and allow for frequent movements of the vessel as work progresses. They are built with durable rubber or hybrid rubber-foam structures, capable of resisting compression over months of use without losing their energy absorption properties.
( Case: At a naval refit facility, a nuclear-powered attack submarine was undergoing a year-long modernization program. The yard installed large panel-type submarine fenders along the entire length of the berth. These fenders not only protected the hull during occasional repositioning but also acted as a buffer against small service craft operating alongside. Midway through the refit, a supply barge accidentally drifted toward the submarine during unloading. The panel fender absorbed the impact, preventing damage to both vessels. Yard officials noted that the fenders required almost no maintenance during the entire refit period, proving their durability under continuous use.)

Characteristics
High Energy Absorption
Designed to dissipate large amounts of kinetic energy during berthing, reducing the risk of hull deformation or structural damage.
Low Reaction Force
Minimizes the force transferred to both the submarine hull and quay wall, ensuring safer docking in various conditions.
Custom Hull Contour Matching
Available in shapes and dimensions tailored to specific submarine classes, ensuring optimal contact and protection.
Corrosion Resistance
Constructed from marine-grade rubber and composite materials that resist saltwater, oil, and chemical degradation.
Applications
Port Harbor Security Barriers
Integrated into underwater security perimeters to absorb impacts from unauthorized submarine intrusions near sensitive port areas.
Submarine Launch Recovery Systems
Used on submarine support vessels or underwater platforms to safely guide and recover unmanned subs (UUVs).
