Zusammenfassung:	Accurate, dependable methods for analyzing operational parameters of subsea control systems and diagnosis/prediction of failures are provided, in particular, methods for detection of leaking and/or clogging in hydraulic control system using recorded pressure signals and evaluating response communication strength (signal amplitude) of field equipment from, for example, subsea control systems. Prediction of failure(s) allows an opportunity to prepare for intervention to minimize the impact of failure before failure occurs, for example, by ordering equipment, tools and/or scheduling an intervention vessel. Similarly, diagnosing a failure drastically shortens the intervention time.
