A method for enhancing a LNG production train that includes connected train components. The method may include steps of: constructing an integrated surveillance system for monitoring operation of the train components; using the integrated surveillance system to measure and record operational data and event data related to, respectively, the operation and a failure event of the train components over a historical operating period; performing a correlation analysis that calculates a correlation between the occurrences of the failure event and the operational data; given results of the correlation analysis, deriving a prognostic rule that indicates a likelihood of the failure event occurring based on values of the operating parameters of the operational data; applying the prognostic rule to current values of the operating parameters and determining therefrom the likelihood of the failure event occurring; determining an advisory related to the determined likelihood of the failure event occurring; and issuing the advisory.

This disclosure describes systems and methods for alarm management. In some embodiments, data associated with a parameter of an asset may be received from an asset and stored in memory. An impact value may be determined for the parameter based at least in part on a rule set. The impact value may be a numeric value associated with the asset and determined based at least in part on a Bayesian belief network (BBN) rule set, a fuzzy logic rule set, or a combination thereof. The impact value may be analyzed based at least in part on an escalation value rule set. In response to analyzing the impact value, the impact value may be prepared for presentation.
