Research aim is creation of new design methods of hull structures of small and high-speed metal vessels made of ship hull steels, or aluminum alloys, improvement of their design methods using modern advances in hydrodynamics and reliability theory. Research methods: theory of ship and ship strength, probability theory, mathematical statistics, risk theory, theory of reliability and security. Theoretical and practical results: Analysis of classifications, wave loads, prospective forms of small and high-speed vessels, as well as their operational and technical indicators has been carried out. The dynamic responses of the high-speed vessels in in agitated sea conditions are analyzed. The serial numerical hydrodynamic studies of influence of the hull shape and motion speed on the amount of resistance are performed. The basic design criteria of ship hull structures are defined. The method of external loads calculation is developed. The serial studies of influence of the hull shape, dimples and motion speed on the amount of motion resistance are performed. Novelty and efficiency of implementation: on the basis of the comprehensive and systematic research of the problem of improvement of efficiency and reliability of small and high-speed vessels many applied tasks have been done using original ideas. New techniques of construction and design of small and high-speed metal vessels are obtained. Field of Implementation: education (education process of the universities which train specialists in Naval Architect), shipbuilding (design organizations and construction bureaus of Ukraine, Shipping Register of Ukraine), water transport (shipping companies).
