Abstract

Abstract Applying non-accident critical events (NACEs) as an alternative measuring method to assess ship collision risk has become popular in recent years. NACEs has shown temporal features in different waters. This study uses the quaternion ship domain method to identify NACEs around the Yangtze Estuary and adjacent coastal waters from the Automatic Identification System (AIS) data in October 2019. The results indicate that NACEs show different temporal features in estuaries and coastal waters. The relationship between tides, channel types and ships is discussed. In addition, we established a statistical method for the occurrence time of NACEs and the state of tides according to the half-tide level and the nearest time. The outcomes of this study provide a direction for exploring the relationship between NACEs and environmental conditions, which is also instructive for the study of the causes of ship accidents.

长江口及邻近海域潮汐非事故临界事件影响的时间特征

摘要近年来，将非事故临界事件（NACE）作为评估船舶碰撞风险的一种替代测量方法越来越受欢迎。NACE在不同水域显示出时间特征。本研究使用四元数船域方法，从2019年10月的自动识别系统（AIS）数据中识别长江口及其邻近海域的NACE。结果表明，NACE在河口和近海表现出不同的时间特征。讨论了潮汐、航道类型和船舶之间的关系。此外，我们还根据半潮位和最近时间建立了NACE发生时间和潮汐状态的统计方法。研究结果为探索NACE与环境条件的关系提供了方向，对研究船舶事故原因也具有指导意义。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
