Topside Control Unit can sometimes include a Valve Signature Emulator. The VSE records and monitors the pressure versus displacement characteristics of the hydraulic actuation of the subsea valves.
Each valve will have its own unique signature. Using this signature data, the behavior of valves during actuation may be monitored and malfunctions such as leaks, incomplete actuation or sticking actuators may be detected.
Valve Signature Emulato (VSE) monitors subsea actuators conditions or performance from topside.
