Large-scale bridges are the lifelines of national transportation, and preventing ship collisions in complex marine environments is a major challenge in the maintenance of many large bridges.

In response to the development trend of the times, NANHAI actively collaborates with research institutions to deeply cultivate the safety operation and protection technology of cross-sea bridges. By utilizing the adaptive buoyancy tank flipping under the impact of ship collision force, the interception net can be vertically deployed from a horizontal state to wrap around the bow of the ship, solving the challenge of "effective interception". This technology achieves the "three protections" goal of protecting both the bridge and the safety of ships and the environment.
