Estimation of Seagoing Ship’s Engine Power Based on Distinguishing Quantity Parameter

The power of main engine must be determined in such a way to let the seagoing ship reaches the predicted, in the agreement with the ship owner, service speed. Significant influence on the main engine power, apart from the ship’s speed, has a geometry shape and the dimensions of the ship’s hull. Begins from the general form of Admiralition’s equation, it is essential to establish the specific quantity parameter for the estimation of main engine power. That parameter can be described by the displacement, DWT, LBT, TEU number, the 14 tons TEU number etc. depends on the type of the seagoing vessel. The estimation of the specified maximum continuous rating SMCR based on the quantity parameter can be practicable in the preliminary design stage because of the small number of the known design data and the importance of the design decisions made at that level. The characteristic quantity parameter to establish the main engine power of the seagoing ship has been determined using the data of the contemporary container ships in operation. The research has been done in the whole range of the container capacity in TEU, where the combustion, reciprocation engines are used to propel the seagoing vessels. The statistical and regression tools have been utilized in the data analysis process to determine the quantity parameter.
