Ship Collision With Bridge And Flexible Energy-absorbing Anti-collision Facilities Research

With the development of Tianjin port and haihe river ports, the ships is developing towards the direction of large-scale which navigate in Haihe River, and the number is growing greatly. At the same time, a number of bridges and other buildings having been Built over the river. The navigable dimension of Haihe River is restricted by the bridges and other hydraulic structures and the navigation rules, it is great necessary to study and optimize the navigable dimension of Haihe River. Based on the research and analysis Haihe River's scale, meteorological and hydrological conditions, over-river structures' scale and shipping traffic data, the paper makes use of the relevant technical specifications and marine technology theory to theoretical analysis and mathematical calculate the required channel scale of navigation ship, and concludes the navigation of available ship of non-navigable river section, and optimizes the navigable dimension combined my experiences in the management of maritime. Finally, the conclusion is verified by computer simulation. The result is that, 5,000-ton bulk carriers and 5,000 tons of liquid chemical ship loaded with state are able to safety through the Xiangluowan Haihe Drawbridge, can't safety through the bridge under the condition of 6 or more wind, ballast and haihe river not flooding dischange. The conclusion of this paper provides a reference for the maritime Supervision of ship safety navigation to some extent.
