Necessity of setting the minimum power level requirements for ice-going ships

Author: K.E. Sazonov

Abstract

The paper discusses the necessity to specify the minimum power levels for ice-going merchant vessels. It is noted that the current RMRS rules often lead to excessive power level requirements, in particular for large-size vessels. It is suggested that ice-going ships should be grouped in two categories: ships operating with an icebreaker's assistance only and ships able to operate in ice-covered waters independently. Operating scenarios for said ship categories are suggested to determine the power requirements consistent with the ice resistance data.

Keywords: ice-going vessel, power, scenario, ice resistance, ice-going capability.
