The invention provides a ship navigation risk assessment method and assessment system, and relates to the technical field of ships, and the method comprises the steps: screening out a plurality of collision risk ships according to an initial navigation state and a ship satellite system, and determining a ship conflict risk coefficient in a planned navigation path according to the planned navigation path and a set navigation path of each collision risk ship; determining the obstacle collision emergency degree between the target ship and each navigation obstacle by using the planned navigation path, and performing obstacle avoidance path search on the target ship based on all the obstacle collision emergency degrees to obtain a risk obstacle avoidance path, determining a ship conflict risk coefficient in the risk obstacle avoidance path according to the risk obstacle avoidance path and the set navigation path of each collision risk ship; according to the ship conflict risk coefficient in the planned navigation path and the ship conflict risk coefficient in the risk obstacle avoidance path, a navigation risk assessment report of the target ship is generated, the collision risk can be predicted in advance, and the safety of ship navigation is improved.
本申请提供一种船舶航行风险评估方法及评估系统,涉及船舶技术领域,依据初始航行状态和船舶卫星系统筛选出多个碰撞风险船舶,根据规划航行路径和各个碰撞风险船舶的设定航行路径确定规划航行路径中的船舶冲突风险系数;使用规划航行路径确定目标船舶与各个航行障碍之间的障碍碰撞紧急度,基于所有的障碍碰撞紧急度对目标船舶进行避障路径搜索,得到风险避障路径,由风险避障路径和各个碰撞风险船舶的设定航行路径确定风险避障路径中的船舶冲突风险系数;根据规划航行路径中的船舶冲突风险系数和风险避障路径中的船舶冲突风险系数生成目标船舶的航行风险评估报告,本申请可以提前预测碰撞风险,以提高船舶航行的安全性。
