Abstract


Ship Collision maritime traffic accidents occur frequently, bring irreparable damage to the lives and property of the people. The ship collisions often cause damage to the structure of the ship, cargo leak, environmental pollution, casualties disastrous consequences. Therefore, both from a security aspect, economic, or from the point of view of environmental protection, the analysis of a ship collision accident has occurred, with reference to a ship collision accident results thus summed up the analysis model has practical significance of ship collision consequences, thus driving the ship cited have proposed a reasonable reference has important significance in order to avoid the collision or the collision loss minimized. 254 from at home and abroad collision incident report translation, finishing on the basis of obtained data of ship collision accident, use of stepwise regression analysis method to study the potential impact on the result of the collision the collision factor and get The elements of the collision system clustering, to determine the functional relationship between the collision elements and collision results. Ship collision accident data has been centralized and standardized processing, eliminating the level and dimension of the impact, the regression analysis to determine the size of ship collision after collision loss touched by ship displacement, collision angle, hitting the front speed and The four elements of the impact of the collision location, and ship touched the displacement and the impact of the collision angle coefficient is significantly greater than the influence coefficient touch before the speed and impact location. Collisional loss can be drawn by analyzing the different elements of the ship touched displacement played a key role in the collision loss results. System clustering algorithm, the ship touched the displacement of the impact on the number of collisions weighted loss marked the raw data naturally into 13 categories, and classification of data instead of the original sample data using the above results, correlation analysis, nonlinear analysis determine the ship touched the nonlinear relationship between displacement and collision losses for the inverse function and curve fitting, and then get a ship collision losses and ship touch inverse function relationship between the displacement model. According to the model shows that, with the ship touched displacement increases, ship collision loss occurs gradually decreasing trend. However, due to the limitation of the number of incidents have been reported, the the collision factor analysis is not very complete, the value of the papers, there is still much further research.
