One of the types of high-risk machinery of oil-and-gas facilities is rotor units: pumps, compressors, separators with wide range of power, pressure, speed, costs, working environments, temperatures and operational resources. Failures and accidents of such machinery can be connected with considerable economic losses and possibilities of severe emergencies.
In order to ensure and increase the resource and safety of rotor machinery for the last twenty years the member-companies of Scientific and Production Unit "RISKOM" were developing methods and systems:
- prompt discrete condition diagnostics of the equipment according to the requirements of normative-technical documentation;
- continuous condition diagnostics of supporting elements by the common criteria and vibration activity parameters;
- continuous and discrete monitoring of rotor units condition based on the results of the current diagnostics and forecast of dangerous conditions (accidents, failures).
These developments allowed for the first time to shape and begin the implementation of a new stage – risk monitoring of rotor units for petrochemical industry. Its methodological nature is the following: by the current condition diagnostic and monitoring data there are quantitative evaluation of accident risk occurrence rates, growth of economic expenses and risks caused by the equipment degradation, reduction of safe run-to failure operation and growth of expenses for diagnostics, monitoring, and reasoning of safe residual life prolonging.
