Conditional online-based risk advisory system (COBRAS)

An advisory system for operating a vessel, comprising:

• at least one system configured to operate the vessel;
• a plurality of sensors configured to sense variables of the at least one system, the variables representative of functional parameters of the at least one system;
• at least one processing unit in communication with the at least one system and said sensors, and configured to:
• generate a first time series of measurements of a first variable of the at least one system over a time period;
• access a second time series of measurements of a second variable over the time period;
• identify, from the first time series, a change in values of the first variable over the time period;
• in response to determining the change in values of the first variable, correlate the first variable with the second variable over at least a portion of the time period;
• generate a notification inclusive of at least a portion of (i) the change in values of measurements of the first time series and (ii) measurements of the second time series of the second variable for an operator to responsively indicate whether the first and second variables are to be correlated with one another;
• and
• in response to receiving an responsive indication from the operator that the first and second variables are to be correlated with one another,
• store an indicator indicative of the first and second variables being correlated with one another,
• otherwise, store an indicator of the first and second variable not being correlated with one another.
