Study on Prevention of Large-sized Bridge from Ship Collision

This paper proposes a pre-warning technique using far-infrared thermal imaging to intercept vessels in risky circumstances. Because far-infrared thermal imaging camera is very sensitive to thermal radiation emanated from the detected objects, it works well and its functionality is independent of both lumination and weather condition. In this paper, the adaptive rising net to capture ship is developed, and the design method to produce a constant resistant force is also proposed. The both developed techniques are applied in Pingtan Strait Bridge to build up a protection system from ship accidental collision.
