1. An apparatus for analyzing a failure in mechanical seal, the apparatus comprising:

  • an equipment data module storing data indicative of a characteristic of a piece of rotating equipment;

    a problem/failure database storing problem/failure data indicative of a characteristic of a failure mode of a mechanical seal associated with the piece of rotating equipment;

    a seal failure analysis module;

    the seal failure analysis module receiving input data indicative of a characteristic of a failure of a particular mechanical seal associated with a particular piece of equipment;

    the seal failure analysis module coupled to the problem/failure database and querying the problem/failure database for failure mode data corresponding to the input data and receiving a query response of data indicative of a failure mode of the particular mechanical seal;

    the seal failure analysis module coupled to the equipment data module, and providing the equipment data module with data indicative of the failure mode of the particular mechanical seal to be associated and stored with the particular piece of equipment;

    a data analyzer coupled to the seal failure analysis module and receiving data from the seal failure analysis module indicative of a failure mode of the particular mechanical seal; and

    the data analyzer coupled to the problem/failure database and querying the problem/failure database with the failure mode of the particular mechanical seal and receiving a query response data indicative of a root cause of the failure mode of the particular mechanical seal.
