Abstract
While operating on the Arctic route, ships may encounter various issues. The ice environment, such as level ice, pre-sawn, pack ice, ice ridge and brash ice, is one of the sources of those issues. There are three different approaches to estimate the ice resistance: analytical methods, numerical simulations, and using empirical formulas. In this paper, empirical formulas are used for the estimation. The main aim of the study is to develop a computer program (I-RES) that predicts an attainable speed for ship of arbitrary shape and estimates the ice resistance. To achieve this, first, various ice environment characteristics such as the level ice, pre-swan, pack ice, brash ice and ice ridge were analyzed. The results of I-RES were compared with Araon model test results. Secondly, to obtain the information of the ship geometry, shape information of arbitrary shape, igs file scaling work of the ship with bulbous bow was performed, and ice resistance and attainable speed were estimated.
