Capturing the hydraulic footprint of an
SSIV
A worlds first: Drallim Industries announces that its Smart Valve Monitoring system has captured the hydraulic footprint of an SSIV in operation 200m off the platform and at 150 metres depth
Drallim Industries announces that its Smart Valve Monitoring (SVM) system has achieved a worlds first by remotely capturing the hydraulic footprint of a Sub Sea Isolation Valve (SSIV) located 200 metres off the main platform and at 150 metres depth IEC61511 determines that safety related system isolation valves should be capable of being tested in order to establish there operability; a significant problem where safety valves are located in inaccessible locations like the sea bed

The benefits of valve partial stroke testing
Valve signatures and partial stroking can be achieved with the simple addition of a pressure transmitter and purpose designed microcomputer can diagnose many types of valve problem
The Drallim SVMR system gathers data about the performance of the valve/actuator and its controlling components such as solenoid valves (SOV) by monitoring the system pressure when a valve moves towards its emergency condition.
SVMR gathers this data through a pressure sensor mounted in the pressure line controlling the SSIV.
Having established a master footprint of the valve/actuator and control components; SVMR can then be programmed to partially stroke the SSIV and monitor changes that may take place in subsequent tests, without disrupting the process.
Additionally and in line with IEC61511 full closures of the SSIV can be compared with the original footprint to check against degrading performance.
