Study On The Technology Of Preventing Vessel Crossing The Non-navigable Channel Structure Of Bridge

While the bridge subjects continue to being the fundamental project for the development of finance, and yet it brings a lot convenient to both the local transportation and economical promotion. But there are negative sides, such bridge will definitely effect the intrinsic navigation area, which would increase the inconvenience. While some ships might sail through the bridge with or without enough alertness to the circumstance. If the situation cannot be stopped, the chance that ship crush the bridge might grow rapidly. So the study on the technology of preventing vessel crossing the non-navigable channel structure of bridge is meaningful and necessary.This essay analysis the ship through non-navigable channel structure accidents happened before, summarizes the list of reasons for ship sailing across the non-navigable channel structure. Checking the device on the ship bridge that make alarm the officer on the floor, try to find out every effective advantages.I have come up several bridge non-navigable channel structure defense technics, including both physical methods and communication. According to the physical methods, there are strong illumination, water interception and guiding board plans. As for the communication, there are limitation for ship draft, AIS reorganization, ECDIS display, information system plan and CCTV watching plan. These designs will be presents with illustrations and declaration, I will also explain the application of these technics, among both advantages and disadvantages.
