Numerical simulation of the hydrodynamics of icebreaking ships 
in clear water

Abstract: The Arctic shelf of Russia belongs to strategically important, promising areas of the country with an enormous potential of natural resources, in particular hydrocarbon reserves. In the view of the growing interest to the development of the Arctic region and the development of its offshore hydrocarbon fields, the actual problem of Arctic fleet selection and optimization upraises, in particular, regarding the special-purpose ice navigation vessels. Despite the fact that icebreakers and icebreaking vessels are designed for ice operations, most of their operating time is spent in ice-free waters, and therefore, the study of hull resistance of an ice vessel in ice-free water is the one of scientific interest. Such study requires thorough and detailed analysis of the shape of vessel’s hull and the characteristics of propeller-steering complex, as well as their interaction in the course of technological operations, and can be performed using automated design systems and engineering analysis. This article presents the results of numerical simulation of movement of an ice-floating vessel in ice-free water: the dependence of water resistance on a vessel’s speed; while visualizing the results of this study allows to determine not only the numerical values of the indicators, but also to evaluate the whole picture of the process, whether pressure distribution, field velocities or fluid flow, which is an undoubted advantage of computer simulation. The data obtained as a result of the study may serve as basis for the formation of recommendations for development of effective hull forms of ice-floating vessels in terms of ship performance.
Keywords: ice-going vessel, ice-free water resistance, hull shape optimization, motion computer modelling.
