A valve monitoring system includes an alert generation system and a memory. The memory encodes baseline acoustic emission data on the valve for a predetermined period of operation. The alert generation system is arranged to receive acoustic emission data for the valve, compare the received acoustic emission data for the valve with the baseline acoustic emission data encoded in the memory and identify valve anomalies in dependence on differences in the received acoustic emission data and the baseline acoustic emission data.
