Abstract

Abstract The complex sea ice conditions in Arctic waters has different impacts on the legs of the Arctic passage, and ships of specific ice classes face different navigation risks. Therefore, the quantitative analysis of the navigation risks faced in different legs has important practical significance. Based on the POLARIS introduced by IMO, the sea ice condition data from 2011 to 2020 was used to quantify the navigation risk of the Arctic Northeast passage. The risk index outcome (RIO) of the Arctic Northeast Passage were calculated. The navigable windows of the route for ice class 1A ships sailing independently under different sea ice conditions in the last decade were determined, with a navigable period of 91 days under normal sea ice conditions, approximately 175 days under light sea ice conditions and only week 40 close to navigation under severe sea ice conditions. The three critical waters affecting the safety of ships were identified. Combined with the navigable windows and critical waters, recommendations on ship's navigation and manipulation and recommendations for stakeholders were given. The method and results provided reference and support for the assessment of the navigation risk of ships in the Northeast Passage and safety navigation and operations of ships, and satisfied the needs of relevant countries and enterprises to rationally arrange shipment dates and sailing plans based on different ice classes of ships.

基于POLARIS的北极东北航道航行风险研究

摘要北极水域复杂的海冰条件对北极航道的航段有不同的影响，特定冰级的船舶面临不同的航行风险。因此，定量分析不同航段面临的航行风险具有重要的现实意义。基于国际海事组织引入的POLARIS，使用2011年至2020年的海冰状况数据来量化北极-东北航道的航行风险。计算了北极东北航道的风险指数结果。确定了近十年来在不同海冰条件下独立航行的冰类1A船舶航线的通航窗口，正常海冰条件下的通航期为91天，轻度海冰条件下约为175天，严重海冰条件下接近航行仅40周。确定了影响船舶安全的三个关键水域。结合通航窗口和关键水域，对船舶的航行和操纵提出了建议，并向利益相关者提出了建议。该方法和结果为东北航道船舶航行风险评估以及船舶安全航行和作业提供了参考和支持，满足了相关国家和企业根据不同冰级船舶合理安排装运日期和航行计划的需要。

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.
