Based on the problems of various types of ships and complicated navigational waterway conditions in the development of series of standard principal dimensions of inland ships, and following the principle of conformity, principle of meeting the required minimum grade, principle of adaptability, principle of unity, principle of practicality and principle of perspectiveness, this paper proposes to divide the tonnage series of ships, forms a number of principal dimension programs by the grid method, establishes a technical and economic model and evaluation index system and determines the optimal principal dimension series program by using the comprehensive evaluation method. Examples are given to demonstrate the “series of standard principal dimensions of dry bulk carriers of transport ships in the Ganjiang River, thus proving the correctness of the established model method.

The Method Research of Setting Standard Principal Dimensions of Inland Ships
