The article discusses approaches to ensuring the state of protection of infrastructure projects, programs and portfolios of projects, in particular critical infrastructure objects, under the conditions of risks and exposure to hazards. The study is based on the analysis of potentially dangerous objects of critical infrastructure (hydraulic structures) in the western region of Ukraine. Their mapping, simulation and modelling of the consequences of possible accidents were carried out using the ArcGIS software environment. The modelling results made it possible to determine the regions with the highest level of flooding risk as a result of accidents at hydrotechnical structures and to assess the potential impact of these emergency situations on other critical infrastructure objects, population and territories. A model of a protective mechanism has been developed to ensure the safety of infrastructure projects, programs, and portfolios. The model accounts for the adaptation of standardized protection project templates to external and internal environmental factors, deviations, and risks. A model of a safety-oriented environment for the functioning of the protective mechanism of infrastructure projects has been formed. It identifies the levels of project protection due to their individual characteristics and network connections. The need for a comprehensive approach to risk management and monitoring of the safety status of infrastructure projects at different phases of the life cycle is summarized and further directions of research are formed.
