E!10648 Condition Monitoring system for flow regulation valve

The project goal has been to develop a system for monitoring the condition of a flow regulation valve, used for controlling the flow of oil/gas in subsea and topside production systems, through an advanced instrumentation solution that will give continuous on-line information. The systems will provide the end user of a better picture of the state of the valve system, and it will also be used to provide input to maintenance programs

Prosjektet er grunnlaget for å kunne levere et robust målesystem for å kunne overvåke tilstanden i strupeventiler. Dette vil typisk være en kontinuerlig oppdatering på ulike tilstandsparametere så som vibrasjoner/sjokk og erosjon/slitasje fra sand partikler. Dette betyr at man hele tiden har kontroll på ventilens og subsea strukturens operative forhold, og man kan også derved lettere kunne planlegge eventuelt preventivt vedlikehold.

Development and qualification of a complete conditions monitoring system for a choke valve based on a needle principle. The system will provide the client with a new diagnostic tool providing continuous on-line information about the state of the valve and the mechanical infrastructure that the valve is a part of, in terms of vibrations, internal erosion and information about the flow regime (e.g. slug flow). The qualification program will be performed according to relevant international standards , e.g. ISO 13628 and DNV recommended practice RP A-203. Typical failure modes of choke valves today is, erosion/mechanical damage related to extreme flow velocities, vibration related fatigue issues and failure of choke position change mechanism..
