The melting of the sea ice in the Arctic area increases the possibility of exploiting the Northern Sea Route (NSR)by economic method. Compared to the traditional routes, navigating through the Northern Sea Route (NSR) will save much distance and time from Asia to Europe, but the ice condition along the NSR is a key obstacle to most vessels. To ensure the safety of the navigation, ice breaker assistance service becomes crucial. This paper introduces the procedure of icebreaker assistance service firstly, and then a static scheduling model is presented to illustrate icebreaker assistance service. Considering real operation, a dynamic model is proposed, and First Come First Serve (FCFS) principle is implemented into models. The experiment results show that this model is beneficial to control the average waiting time, while it may leads to wait too long for some vessels. And the average fuel cost of each trip remains stable even increasing service request.
