  • System and Method for Monitoring a Health State of Hydrocarbon Production Equipment
    Publication number: 20090192731
    Abstract: A device for monitoring the health state of hydrocarbon production equipment is disclosed. The device has a plurality of targets, which are associated with the hydrocarbon production equipment. A record of the initial target positions and/or dimensions relative to the hydrocarbon production equipment is created. A sensor that is compatible with the targets is used to observe the targets and produce a sensor output. An analysis device uses the record of the initial positions, dimensions and the sensor output to determine one or more health state parameters, which may be used to determine the health state of the hydrocarbon production equipment.
