北极地区海冰的融化为北极海洋运输系统（AMTS）的发展开辟了新的视野。如果船舶冰级不符合冰情条件，破冰船协助单船。随着船舶数量和护航行动的增加，护航船舶（破冰船）与被护船舶发生碰撞的风险也随之增加。鉴于此，本文提出了一种护航船舶与被护航船舶安全距离和碰撞风险的计算模型，以利于北极沃茨船舶的安全航行。分析了连续破冰条件下护航作业中破冰船和被护船舶的航行特点，基于船舶跟驰理论，提出了变冰况下安全距离的定量计算模型。所提出的模型是能够量化的安全距离间隔在一个可接受的碰撞频率在不同的冰条件下，以及破冰船和护送船舶的运动特性。最后，对“永盛”轮与“50 LET POBEDY”轮的安全距离进行了实例计算。结果表明，该模型能够准确计算出“永盛”号与“50 LET POBEDY”号之间的安全距离，为冰区航行提供理论指导。
Melting of sea ice in Arctic areas has opened up new horizons for the development of Arctic Marine Transportation Systems (AMTS). An icebreaker assists a single ship if the ice classification of the ship does not meet the ice conditions. With the increase of the number of ships and escort operations, the risks of collisions between escorting ships (icebreakers) and escorted ships have also increased. In view of this, a calculation model of the safety distance and collision risks between escorting and escorted ships is proposed in this paper in order to facilitate safe navigation in Arctic ice-covered waters. The aim of the paper is to analyze features of navigation concerning icebreakers and escorted ships in escort operations under continuous icebreaking conditions, where a quantitative model is proposed to calculate safety distances under varying ice conditions based on the ship-following theory. The proposed model is able to quantify safety distance intervals at an acceptable collision frequency under varying ice conditions, as well as the movement characteristics of icebreakers and escorted ships. A case study is carried out to calculate the safety distance between “YONG SHENG” and “50 LET POBEDY”. The results show that the model can accurately calculate the safety distance between “YONG SHENG” and “50 LET POBEDY”, which can provide theoretical guidance for ice navigation.
