Summary

 
Object and purpose of research. The object of this research is the Leader icebreaker; the purpose is to assess the icebreaker’s ability to move in stormy seas with minimum allowable speed as per IMO requirements
Subject matter and methods.The main methods of investigation is analysis of the icebreaker model test data and methods to estimate the towing resistance and propulsion performance in waves
Main results. Propulsion performance of the Leader icebreaker was estimated for survival conditions in stormy seas. Wind resistance and added resistance in irregular waves were included, as well as the influence of stopped propellers on the icebreaker resistance in survival mode was considered.
Conclusion. It is shown that the Leader icebreaker meets the IMO recommendations to move at a speed of 6 knots against the wind force 8 in the Beaufort scale and corresponding sea state.
