INFUTURE: Inland Waterway Vessel Concepts

Team of inland waterways specialists from the Admiral Makarov State University of Maritime and Inland Shipping has finalised their report on Inland Waterway Vessel Concepts.

This final report is accomplished within the WP3 of the “Future Potential of Inland Waterways”, INFUTURE, financed by the CBC Program South-East Finland-Russia, 2014-2020.

Currently, an increase in the block coefficient is considered as one of the promising directions to increase the economic efficiency of ships and, in particular, river-sea going ships in restricted navigation areas.

It is noted in the professional literature that an increase in the carrying capacity of ships due to an increase in the block coefficient can significantly increase the shipowner profit margin. At the same time, there are authors, who believe that an increase in water resistance to ship movement will lead to a corresponding increase in operating costs, and economic effect of an increase in the block coefficient will not be so significant.

Earlier in the report on WP3 of INFUTURE project, a methodology was presented that allows estimating the optimal value of the block coefficient of a ship operating on a certain selected line and the results of calculations in relation to the line connecting the inland waterways of the Russian Federation with the inland waterways of Finland were presented. It should be noted that, due to the lack of sufficient data in the research literature on the resistance of ships with highblock coefficients, the water resistance to the movement of such ships was extrapolated in the calculations.

In the course of supplementary work, model tests of two variants of a large-scale ship models were carried out in the towing tank of Admiral Makarov State University of Maritime and Inland Shipping, which allowed to clarify the results of a previously performed feasibility studies. Within the framework of the INFUTURE project, the first variants of the vessel models were also tested in the towing tank of the AALTO University, Finland, moving in open water and in ice conditions. Due to the insufficient amount of data on the movement of future ships with high block coefficient in storm conditions, tests of a seaworthiness model of the ship were carried out in the towing tank of the AMSUMISat head sea conditions. At the final stage of the works, an assessment was made of the maneuvering characteristics of the ship with a high block coefficient. The results of model tests, as well as their analysis, are presented in the report.
