The world is immersed in a technological revolution based on the management, use and operation of information. Data, if managed correctly, can add great value to the efficiency of industrial systems. Among the countless methods of obtaining value from data, one of the most exploited is that which focuses on the early identification of deviations from normal operation, the so-called predictive monitoring.
What is predictive monitoring?
The main objective of this line of activity is the early detection of events (for example, errors, deterioration, etc.), with the aim of improving the reliability, security and performance of the monitored systems.
The maximum amount of time to act is achieved thanks to the early detection of errors and deterioration, alleviating any possible damage caused. Likewise, maintenance costs are reduced thanks to the timely planning of activity and replacement of parts.
How does it work?
From data records, which include the operational and environmental conditions at all times, the predictive monitoring techniques identify any incipient deterioration or errors in the equipment. From the representative historical records on the normal state of the equipment in different function modes and environmental conditions, different models can be developed which are able to estimate, in real time, the value of each of the variables present in the process for operational conditions and given surroundings. These estimated values are compared with the real values of the variables in order to obtain the deviation between the estimated and real value, as precursors to any abnormalities in the operation or condition of the equipment.
What is it used for?
Predictive monitoring can be used in a wide variety of systems and equipment, including dynamic equipment such as turbines, pumps, compressors, and static equipment such as condensers, heat exchangers, reactors, etc. This technology therefore provides valuable results for energy production plants (nuclear, combined cycle, wind, hydraulic, solar thermal, etc.), oil and gas plants and for the aviation and rail industries, undoubtedly a wide range of sectors.
It is generally used with equipment and systems with a defined operation pattern, which have a history of operations and are sufficiently censored to provide information on their status. Its installation is quick and flexible and can be made using readily available instrumentation.
What do we do Tecnatom?
Tecnatom is currently applying this line of work to its internal developments as well as to commercial predictive monitoring tools. It is working with different pieces of equipment (water pumps, gas turbines, vapour turbines, wind turbines, etc.) in various plants. The result of this work is integrated in the Tecnatom’s monitoring centre, where the results from these tools are combined with the process knowledge of our experts to add maximum value when optimising a plant’s and other industrial facility’s operations and maintenance.
