Marine/Bridge Prevention

A 500-ton ship suddenly ran towards the bridge at a speed of 7 knots out of control. At this critical moment, several floating rubber airbags quickly floated on the sea surface. They are connected to the positioning buoys at the ends, and they instantly form a "protective chain" of more than 100 meters long on the sea surface, which protects the bridge tightly. When the out-of-control ship collided with the "protection chain", the rope on the "protection chain" suddenly disconnected slowly like a "zipper". After consuming the ship's kinetic energy, the out-of-control ship was stopped intact.

NANHAI invented rigid and flexible matching guiding pier anti-ship technology.Establish a theoretical analysis of the anti-collision device with rigid-flexible matching under impact load.In the world's first actual ship impact test, the ship hit the anti-collision facilities 12 times with different loads, different speeds, and different angles, and the impact force was reduced by 55%-75%, realizing the "three indestructible" bridges, ships, and anti-collision facilities.
