摘　　要：针对破冰船护航下船舶碰撞与冰困事故风险评估问题,本文根据破冰船与跟驰船之间、跟驰船与海冰之间的相互关系,并基于人工势能场理论提出破冰船护航下船舶航行风险场的概念和模型,其中包括破冰船风险场和海冰风险场。破冰船风险场量化破冰船与跟驰船之间的碰撞风险水平,海冰风险场量化跟驰船与海冰之间的冰困风险水平。根据该模型提出破冰船与跟驰船之间安全跟驰距离的计算方法。最后基于Tian You轮2018年北极编队航行数据,应用破冰船护航下船舶航行风险场模型开展仿真实验,仿真结果验证了航行风险场模型的有效性,证明了本文建模方法能够为破冰船护航下船舶安全跟驰研究提供理论方法支撑。To assess the risk of a ship colliding and getting stuck in ice accidents,this study aims to analyze and quantify the ship navigation risk for icebreaker escort operations concerning the mutual relationship between the icebreaker and the assisted ship following the icebreaker and that between the assisted ship and sea ice.We propose a concept and model of a ship navigation risk field under an icebreaker escort operation based on an artificial potential field,including the icebreaker and sea ice risk fields.The icebreaker risk field quantifies the collision risk level between the icebreaker and the assisted ship,while the sea ice risk field quantifies the level of collision risk between the assisted ship and sea ice.The model can calculate the safe following distance between the icebreaker and the assisted ship.Finally,based on the marshaling navigation data of the TianYou ship in the Arctic,2018,a ship navigation risk field model for an icebreaker escort operation is constructed for simulation verification.Results show that the proposed model is feasible and practical,which can theoretically support safety research following the distance between the icebreaker and the assisted ship under the icebreaker escort operation.
