C is one of the top con- tributors toward unplanned shutdowns in offshore sub- sea production systems.

Current practice includes a reactive approach to fail- ure management including equipment replacement or a retroft solution, which can be costly. Condition monitoring of control equipment using existing operational data can provide leading indicators of equipment degradation and potential failure. This approach enhances visibility of equipment health, estimates time to failure and increases
