| (54) | Blow out preventer (bop) corroborator |
| (57) Systems and methods are provided for supplementing existing management methods for
and corroborating condition and performance of a blow out preventer for a submerged
well. The corroborator is located on the blow out preventer and includes a flow meter
external to a pipe to measure flow inside the pipe, a pipe joint locator, a ram seal
confirmation agent, a dedicated communication connection from the corroborator to
a computer topside. Data from at least one sensor topside, which may represent a mud
tank level, is also received. The computer is enabled to calculate a probability that
a malfunction related to the well occurs. The computer may be configured to implement
a Principal Component Analysis model of the well based on historical data, to assess
a likelihood that a threshold value will be surpassed based on collected sensor data
and to generate an alert. The computer implements instructions to perform steps of
the present invention.
