Economic Justification of Design Features for a Universal Dry Cargo Vessel

The economic efficiency of ships is an important indicator of transport vessels, and estimating the economic efficiency of ships is an important task in making investment decisions during the early stages of shipbuilding. This article, based on semi-theoretical and semi-empirical formula methods using the prototype ship of the RST12C project as a basis, estimates and analyzes the main economic indicators of mixed-navigation oil/chemical tankers according to different cargo capacities and speed combinations, for reference by relevant departments.
