Improvement In Preliminary Determination Of Energy Demand For Main Propulsion, Electric Power And Auxiliary Boiler Capacity By Means Of Statistics As An Example Of Modern Ro-Ro Vessels

The paper presents the method of estimated main propulsion power, electrical power and auxiliary steam delivery of the modern ro-ro vessels by using statistical method of calculations. The statistical researches were executed to determine dependencies among the main propulsion power, electric power and heating power as a function of selected basic ship parameters. The reference list of the modern ro-ro vessels was used in the analysis. The chosen ships were selected mainly from the studies of The Royal Institution of Naval Architects elaborated by the most eminent authors of the world shipping enterprise running their articles in a years issue SIGNIFICANT SHIPS OF YEAR. The chosen as the independent variables are the ship parameters being in a logical connection with the main propulsion power, electrical power and steam production of the vessel. Regression analyses were executed by means of the least squares method. Each determined formula was subjected to the statistical verification and the correlation coefficient between the obtained formula and analysed input data was determined.
