The subject of the study is the safety of marine hydraulic structures. Estimation of stability of marine hydraulic structures in the design position under the influence of wind waves, drifting ice formations and seismic effects on the basis of modern methods of physical and mathematical modeling. Assessment of natural and man-made risks during the construction and operation of port and offshore structures. The purpose of the study is to consider a whole range of problems related to construction, logistics, risk analysis and management decisions, as well as appropriate organizational and legal support before and after extreme situations. Research methods - full-scale experiment, construction and analysis of mathematical models. Results and their novelty. A technique for conducting field studies of seismic stability of marine hydraulic structures has been developed. A dynamic model of hydraulic structures is constructed and analyzed. The data obtained as a result of the analysis of their behavior under dynamic influences. Calculation schemes of offshore hydraulic structures have been developed, which will become the basis for the next stage of calculations. The complexity of the study is due to its complex nature, synthesis of different directions (development of models of work of hydraulic engineering structures, development of models of loads of "ice, wave, seismic" acting on structures, development of methods of calculation of indicators of reliability and sustainability of structures, management of reliability and risk,) improving the productivity and performance of the entire port, not its individual parts. The authors have created and developed new trends in the field of earthquake-resistant construction. Studies of seismic stability of berthing structures with regard to spatial work and seismic processes have been performed. Basic regularities of spatial deformation are formulated, scientific bases of modeling of berthing structures are developed, models of interaction of structures with traveling seismic wave are created. Basic research in the field of decomposition of large systems of equations made it possible to create a theory of simulation modeling of berth structures. On the basis of this theory, the scientific team performed the following important for Ukraine and Odessa work - scientific and technical support for the design of especially responsible structures. The R&D results can be put into practice in the activities of maritime industries in the construction and operation of structures, to enhance the process of managing technical and financial and economic security. Implementation of the completed developments will help to increase the efficiency of management of the state service of sea and river transport of Ukraine. The results of the R&D are recommended for use by the Ministry of Infrastructure of Ukraine, Ukrmorrichflot, the administration of seaports of Ukraine, water transport companies, as well as in the educational process in training and advanced training of water transport specialists. Application area - maritime transport.54815481 Product Description popup.authors Єгупов В.К. Безушко Д.І. Гришин А.О. Дорофєєв В.С. Латій М.Ф. Маліновський В.А. Постан М.Я.
