Estimation method of ship main propulsion power, onboard power station electric power and boilers capacity by means of statistics

This paper describes an estimation method of ship propulsion power, onboard power station electric power and boilers capacity for the number of ship types by means of statistics. A wide population of being in operation and new built container ships, ferries, ro-ro vessels, passenger cruisers, tankers, LNG carriers and bulk carriers was taken into consideration on the base of similar ships list. The list of similar ships was prepared mainly on data given in works of THE ROYAL INSTITUTION OF NAVAL ARCHITECTS published in famous year’s issue the SIGNIFICANT SHIPS OF YEAR. As a result of analysis formulas for calculations of ship propulsion power, onboard power station electric power and boilers capacity for considered types of ships were obtained. Formulas elaborated by means of described method are characterised by good representation of described values as they have high coefficients of correlation and regression determination.
