Abstract

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.
