A safety valve analysis system comprises: a plurality of sensors, including a displacement sensor (12) arranged to measure displacement of a valve member, an acoustic sensor (13) arranged to measure noise from within a valve body and a pressure sensor (11) arranged to measure fluid pressure at a valve inlet (4); data acquisition means (15) arranged to receive signals from the sensors and generate corresponding valve data; and processing means arranged to generate an output indicative of the condition of the safety valve based on the valve data. |
