摘要

本研究根据国家规则和国际建议(《北海航线水域航行规则》和国际海事组织建议)调查船舶在冰况下操作限制的可变性。例如,2017-2019年期间将考虑喀拉海地区。考虑了来自两个数据集的船舶数据:(1)北海航线管理局数据和(2)自动识别系统数据。基于极地作业极限评估风险指数系统(POLARIS),利用每艘船舶的冰级信息(浓度和类型)得出作业极限,并将结果与最新的北海航线准入标准进行比较。初步结果表明,国家规则通常比国际建议更严格,但在某些情况下,国家规则对操作的限制较少,因为当国际建议表明意外事件的概率升高时,允许冰级PC7/Arc4的船舶运行。

Agree – Disagree: Comparing Traffic Limitations in the Kara Sea
This study investigates variability of ships’ operational limitations for ice conditions in view of national rules and international recommendations (the Rules for Navigation in the Water Area of the Northern Sea Route and the International Maritime Organization Recommendations). As an example, the Kara Sea region is considered for the period of 2017–2019. The ship data from two datasets were considered: (1) the Northern Sea Route Administration data and (2) the Automatic Identification System data. For each ship’s ice class, the ice information (concentration and type) was used to derive operational limitations based on the Polar Operational Limit Assessment Risk Indexing System (POLARIS), and the results were compared with the newly updated Northern Sea Route access criteria. Preliminary results indicate that national rules are generally stricter than international recommendations, however on some occasions, the national rules impose lesser restrictions on operations as ships with ice class PC7/Arc4 are allowed to operate when the international recommendations suggest an elevated probability of an accidental event.
