For terminals located in extremely cold seas，to be operated uninterruptedly in the whole year，appropriate ice control measures shall be taken，and ship mix shall be arranged accordingly for the throughput demand. An ore loading dock project in the arctic area of Canada is taken as an example in this paper. Based on the natural conditions，ice conditions and operation requirements，this paper proposes applicable ice ship class，ice control measures such as ice management vessels and air bubbler system，as well as ship mix for the annual throughput. Berth occupancy is also calculated to demonstrate the proposed ship mix. The proposal of this paper can provide reference for the design of similar projects.
