Abstract

Abstract The Autonomous Navigation System (ANS) constitutes a critical key enabling technology required for operating Maritime Autonomous Surface Ships (MASS). To assure the safety of MASS operations, the effective identification of potential objects and target ships interacting with the own MASS is quintessential. This study proposes a systematic method to identify the items interacting with the own MASS. This method is based on a similar approach previously employed for the encountering items’ identification in robotics, which is customised herein for the MASS needs. The developed method is applied to a short-sea shipping MASS. The environmental features, agents and objects related to her navigation are identified and ranked based on the frequency of encounter and the potential collision consequences. The results demonstrate the ability of the method to identify additional items in comparison to Automatic Identification System based data. The interactions with the small ships are considered as the most critical, due to their potential accidental consequences and their exhibited high frequency of encounter. This study results are employed to support the ANS design and testing of the investigated ship.

一种识别和排序影响自主船舶航行的物体和危险相互作用的方法

摘要自主导航系统（ANS）是操作海上自主水面舰艇（MASS）所需的关键使能技术。为了确保MASS操作的安全，有效识别与自身MASS相互作用的潜在物体和目标船舶是至关重要的。本研究提出了一种系统的方法来识别与自己的MASS交互的物品。该方法基于之前在机器人中用于遇到物品识别的类似方法，该方法是根据MASS的需求定制的。将所开发的方法应用于短距离海运MASS。根据相遇频率和潜在碰撞后果，识别和排序与该船航行相关的环境特征、代理人和物体。结果表明，与基于自动识别系统的数据相比，该方法能够识别额外的项目。与小型船舶的相互作用被认为是最关键的，因为它们具有潜在的意外后果，而且它们的遭遇频率很高。该研究结果用于支持被调查船舶的ANS设计和测试。

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.
