Egorov G. Methodology of maintenance of reliability and safety of hulls of ships of restricted naviga-tion area

The thesis is dedicated to the solution of the problem of reliability, safety and efficiency of ships in restricted navigation areas (SRNA) at stages of a life cycle with the use of risk-oriented approaches. The concept of SRNA of a new generation is worked out. The feasibility of increase of a block coefficient of SRNA is proved and implemented. The theoretical fundamentals for selection of principal elements of SRNA are advanced. The methods of total strength of hulls of the inland waterways ships are developed. The computation methods of estimation of rated speeds of wearing is worked out. The unified marine and river classification of SRNA by navigation areas is offered on the basis of equivalent risk principle. The rating assessment of technical condition of a particular vessel is developed. The results are implemented in 12 projects of SRNA, by which are already constructed or being under construction 31 vessels.
