Abstrakt:

Bridges across navigation channels are under the threat of accidental ship collisions. Many research works have been conducted to investigate the crashworthy device against ship-bridge pier collisions. However, the existing bridge pier protection facilities, mostly based on absorbing ship kinetic energy, are large structures with high strength, resulting in large collision forces that may cause ship damage. In this paper, flexible anti-collision technology is developed, which protects the bridge pier based on the ship's course guidance principle, hence taking away the huge kinetic energy of the ship in the process of collision. The pier flexible crashworthy device has a compact structure and can greatly reduce the impact force of ships, protecting both the bridge and the ship. The reliability and effectiveness of the technology have been verified through off-shore impact tests.
