The introductory part of the paper describes the process of collecting and analyzing data for the preliminary phase of shipbuilding. With the adopted data, the shape of the ship used in the work is modeled. The spatial and weight concept were selected from a similar ship 8, and a preliminary distribution of space by decks was made. Through resistance and propulsion, the values of resistance and power were estimated, which are compared with the values of a similar ship 4. from which the concept of power was adopted. The register according to which the polar cruiser is made is DNV, from which the validity of the results was checked. Through the propulsion, the characteristics of the propeller are determined and the engine is selected with a given limitation of the design requirements. The material used is AH32 which is specified by the register for parts exposed to cold. After propulsion, the strength of the ship is calculated using the "Siemens FEMAP" and "Mars2000" programs, in which the allowable stresses, critical resistance moments and longitudinal strength are checked. A general plan is made below, and all spaces arranged on decks are described. Once the layout of the space on the ship is known, the stability calculation is performed in the program "MaxSurf Stability" for balance analysis, hydrostatic data for upright position, stability at higher angles of inclination, unsinkability and longitudinal strength. This is followed by a check of the marine properties in the "MaxSurf Motions" program, where the properties are checked at certain angles of the oncoming waves. The sailing route was adopted according to similar polar cruisers in the Antarctic area for whose sea conditions the ship was designed. It also checks the speed drop for a particular sea condition, hitting the bow and watering the deck. The energy efficiency index should be met for the fuels used, and finally an economic analysis is performed and the profitability of the product is checked
