Abstract

Reduced order modeling is used in the present systems and methods for monitoring the health of a system and is particularly useful in monitoring the health and estimating the remaining useful life of blow out preventer (BOP) annular used in an oil or gas well. A reduced order model is a linear low order characterization of the system that describes the annular behavior with a small number of parameters that can be interpreted physically. The reduced order model is then identified and adapted in real-time in order to detect the change in the system behavior and characteristics. This adaptation helps in drawing conclusions on diagnostics and prognostics of the physical system.
