Project Background：After the 2000 USS Cole attack, the U.S. Navy strengthened base security and introduced the Dunlop inflatable fender barrier system in San Diego Bay.
System Parameters：8 feet in diameter, 82 feet per section, made of rubber-coated fabric, capable of intercepting small boats with kinetic energy up to 2 million pound-feet.
Application Effect：Effectively resists threats from high-speed small boats carrying explosives and protects the safety of warships in the base.

 

Core Design：With rubber airbags as the core, it is normally submerged underwater and quickly inflates to float when sensing approaching ships.
Full-Scale Ship Test：A protective chain composed of 5 12-meter-long airbags successfully intercepted a 500-ton test ship at 2-7 knots (10 times of lossless interception).
Application Scenarios：Xiangshan Port Highway Bridge, Pingtan Strait Bridge, Zhanjiang Bay Bridge, etc., avoiding ship-bridge collision accidents for many times.

 

System Type：Inflatable flexible diaphragm dam (rubber dam), the world's only corrugated pipe weir used for storm surge protection.
Key Application：First activated during Storm Pia in 2023, inflates to block waterways and prevent seawater backflow.
Core Advantage：More flexible in responding to tidal changes and sudden storms than rigid barriers, effectively protecting surrounding areas from floods.

 

Deployment Environment：Karnaphuli River, tidal range 3-5 meters, current speed 4-6 knots, maximum water depth 35 meters.
System Specifications：Total length 124 meters, spliced by 20-25.5 meter units, with navigation gate in the middle section, rated energy absorption 319 kJ.
Protection Capacity：Resists 7.62mm caliber gunfire, maintains 50% diameter after damage, with both security and debris interception functions.
