This paper focuses on a comparative analysis of the most important parameters of an icebreaker ship’s sustainable operations: the operational availability, power performance and power performance deficiency of the multi-state Multi-Power Source Traction Drives of Norilsk-type Arctic icebreaker ships. These parameters have a significant impact on the correct choice of the propulsive system of icebreaking vessels. The parameters’ evaluation was based on statistical operational data on Arctic icebreaker ships with diesel-geared traction drive. The Lz-transform approach was used to arrive at a solution of that problem. This approach drastically simplifies the solution compared with the straightforward Markov method.
