One approach to determining the efficiency of using hydrofoil vessels

Abstract

The article is aimed at facilitating the solution of one of the actively discussed problems – the revival and development of high-speed passenger transportation by hydrofoil vessels (HV), which will undoubtedly lead to an increase in the prestige of government agencies among the population. In modern conditions, this problem can be solved only through government support in the form of subsidizing operating and capital costs and preferential leasing. This requires methods for determining operating costs and assessing the economic efficiency of river HVs during operational justifications at the stages of pre-project selection and design of new vessels, selection of their operating areas. Currently, such generally recognized or approved methods for river HPVs are absent. The use of only known technical indicators when selecting an HV is insufficient. In the article, based on the analysis of existing methods for determining the efficiency of high-speed vessels in sea transport, a criterion is proposed that takes into account both current methodological recommendations and modern economic conditions, and is entirely based on the principles of Lurye A.L. At the same time, to increase reliability and authenticity, technical (physical) and cost indicators must be used in combination during justifications and especially in the early stages of design research.
