The invention relates to the technical field of ship safety, in particular to a ship yaw collision risk assessment method and system, and the method comprises the steps: obtaining the ship traveling real-time data of a bridge area water area; a ship collision risk assessment model is established, and ship microscopic risks are assessed; and according to an evaluation result, determining whether the ship has a collision risk and judging a collision risk level of the ship. According to the ship microscopic collision risk assessment method, the defect that a traditional method is low in assessment accuracy in a dynamic water area environment is effectively overcome, the safety of water area traffic is improved, the ship microscopic collision risk is assessed more standardly and accurately, and a more reliable decision basis is provided for ship operators and management mechanisms.

    本发明涉及船舶安全技术领域,具体涉及一种船舶偏航碰撞风险评估方法及系统,方法包括:获取桥梁桥区水域船舶行驶实况数据;建立船舶碰撞风险评估模型,对船舶微观风险进行评估;根据评估结果,确定船舶是否有碰撞风险并判断船舶的碰撞风险等级。通过本发明,有效避免传统方法在动态水域环境下评估准确性低的不足,提高了水域交通的安全性,更标准且精确地地评估船舶微观碰撞风险,为船舶操纵员和管理机构提供了更可靠的决策依据。
