Analysis of the impact of operation conditions on the bulk carriers design characteristics

The paper presents the results of a comparative analysis of the design characteristics of ships currently used for coal transporting from the ports of Far East of Russia to the Asia-Pacific countries with mathematical modeling and optimization results oriented to the economic criteria. The effectiveness and expediency of using ships in the certain directions of coal transportation is considered. The results of the analysis of the influence of operating conditions to the optimal values of the design characteristics (speed and payload capacity) and economic criteria of the functional efficiency of bulk carriers are given. The mathematical model for optimal values of the design characteristics of bulk carriers was used. The model takes into an account basic calculations of ship design and theory disciplines which are used at the initial stages of design. The calculations were made for the operating conditions of a specialized high-tech coal transshipment terminal with is located in the south part of Primorsky Krai. The economic efficiency affecting factors and their variations ranges were analysed. The research results can be used at the preliminary stages of ship design for general characteristics calculation and transportation costs optimization.
