Abstract

 

Intensification of cargo transportation by sea in the Arctic region puts forward new requirements for the designed ships intended for operation in the North conditions. Ships operating in the Arctic region shall be specially designed to meet the requirements for navigation in ice conditions. It is necessary to ensure the required characteristics of ice-going capabilities by designing hull forms that meet these requirements. In addition, their power plant shall meet modern requirements as to regulating the amount of harmful emissions and have low fuel consumption, maneuverability and energy efficiency. For a preliminary efficiency assessment of the ship's operation in ice, it is necessary to determine the relationship between the parameters of the energy efficiency and the characteristics of ice-going capabilities. This paper proposes a method for determining the coefficient expressing this relationship for ships of various types operating in ice navigation conditions. The coefficient, in the future, will allow for a comprehensive comparison of the operation efficiency of existing ships in ice navigation conditions, as well as for assessment of newly designed ones.
