The article is devoted to real-time monitoring of the equipment failure omission risk using data from computer systems for accidents prevention and equipment health monitoring. To prove availability of connection between the equipment operating time in different states and the consequences that arise from adverse events, the necessity to determine such events and specify their consequences, as well as to calculate their occurrence frequency depending on operating time, has been shown. The article includes assessment of possible and probable failures consequences for the units being operated in an unacceptable technical state according to results of the monitoring systems implementation at Russian refineries. The authors have concluded that the automatic calculation and real-time monitoring of the units failure omission risk at hazardous production facilities can be performed only by stationary systems for the equipment health monitoring and presented to all the refinery management levels. This allows the management not only assumes but knows the existing risk level, which is conditioned by the prevailing housekeeping, as well as to make decisions aimed at risk decrease, i.e. to provide the most effective strategy of risk management.
