Statistical Analysis of Principal Dimensions of Dry Bulk Carriers Navigating on Yangtze River Based on Big Data

Abstract

The shipping of the Yangtze River has been developing rapidly, the large scale and standardization of ship dimensions have also developed along with the development of China’s economy since entering the 21st century. As a main ship type of the Yangtze River shipping, the dry bulk carriers have changed greatly in the principal dimensions. The characteristics and regression formulas of the principal dimensions in the past are not applicable to the new ship type. On the basis of big data statistics of the dry bulk carrier over 1000 tons navigating on the Yangtze River, the distribution of the transport capacity and distribution of ship age are analyzed, and the linear formula between the gross ton and dead weight is summed up. Then the statistical characteristics of the important parameters of ships such as the ship length, the ship width, the design draft and the diameter of the propeller are analyzed. The research results can provide an important reference for ship design, ship form development, technical standard research and navigation management.
