Therefore, the development of shipping and port operations in Hebei will face a new challenge at the same time.Port waters are traffic accident hotspots which are also severely affected by the maritime accidents. However, as the volume of traffic grows rapidly, it should be paid more attention to the navigation safety in Qinhuangdao Port. Based on the investigation and analysis of natural conditions and navigable waters in Qinhuangdao fairways, this paper analyzes some factors that affect inbound and outbound navigation safety in Qinhuangdao Port and identifies the evaluation index system. It also evaluates the navigable environment in Qinhuangdao Port by using a fuzzy comprehensive evaluation model.This paper aims to provide valuable preferences for the safe navigation and reduce maritime accidents in Qinhuangdao Port.
