Digital twin
A virtual replica of a physical asset, process, or system — used for real-time monitoring, simulation, and predictive safety analytics.
A digital twin is a live digital representation of a physical asset (pump, compressor, reactor), process (production line), or system (plant, refinery). It ingests real-time sensor data (IoT), historical operational data, and engineering models to simulate behaviour, predict failures, and optimise performance. In QEHS contexts, digital twins are used for predictive safety — modelling gas dispersion, explosion overpressure, or evacuation scenarios — and for linking equipment condition to permit-to-work risk assessments.
