Systems and methods for non-invasive determination of properties of pressure vessels

A system for determining target properties of a pressure vessel, the system comprising:

• a signal generator acoustically coupled to a fluid contained in the pressure vessel and disposed at an external surface of a wall of the pressure vessel, the signal generator to directly emit acoustic signals into the fluid;
• a plurality of sensors acoustically coupled to the fluid and disposed externally to the pressure vessel to detect the acoustic signals;
• a gas sensor configured to determine dissolved gas parameters of the fluid contained within the pressure vessel;
• a control device interconnected with the signal generator and the plurality of sensors, the control device configured to:
• control the signal generator to directly emit acoustic signals into the fluid;
• obtain sensor data from the plurality of sensors, the sensor data representing the acoustic signals as received by the plurality of sensors;
• obtain the dissolved gas parameters from the gas sensor;
• compute, based on the sensor data and the dissolved gas parameters, the target properties of the pressure vessel;
• and
• output an indication of the target properties,
• wherein the target properties comprise one or more of:
• a thickness of the wall of the pressure vessel, and a location of a fault in the pressure vessel.
