Economic efficiency of development of ship shafting diagnosis system

The ship shafting ensures the operation of power plants for a significant number of ships of the Russian fleet. Improving the methods of increasing its reliability is an important and urgent task. Part of the loads acting on the propeller and intermediate shafts are random in time and magnitude, that is why it becomes necessary to create a diagnostic system to record the loads and assess the technical condition in real time. The project for creating such a system is knowledge-intensive and involves a large amount of R&D and attraction of investments. There has been suggested an approach to substantiate R&D based on the description of its novelty, commercialization prospects, market analysis and segmentation, business model and calculation of planned economic indicators. The results of the statistical analysis of ship shafting failures are given. An approach is proposed to improve the reliability of a ship power plant based on the simultaneous registration of torsional, transverse and longitudinal vibrations. A quantitative assessment of the market volume was carried out, taking into account the volatility of the exchange rate. The total market size is estimated by the number of vessels in operation by using the methodology of PAM, TAM, SAM and SOM indicators. The target audience of the project was determined by available distribution channels. A nine-block model and commercialization scheme have been developed. The results of calculating the economic efficiency of the investment project are given: net present value and internal rate of return. The results obtained and the applied approaches can serve as a basis for substantiating the investment attractiveness of high-tech projects in the shipbuilding industry.
