Safety Valve Control System

Improve performance with electric-over-hydraulic emergency shutdown control that enables condition-based monitoring and maintenance.

The mSafe Safety Valve Control System enhances well safety, increases operational efficiency, lowers maintenance costs and maximizes production with features to:

  • Open, close, and monitor hydraulically actuated safety valves -- remotely, automatically, and at the well site.
  • Implement condition-based monitoring and maintenance using valve status data communicated via SCADA or downloaded from onboard memory, and supported by web-based diagnostics support.

Monitoring & SCADA Control

Electronically Assisted Hydraulic Control

Field-proven in Latin and North America, the mSafe design integrates electronic control and an electro-hydraulic pump to ensure the safety and performance of hydraulically actuated safety valves used in emergency shutdown applications. The controller precisely and reliably manages valve position while monitoring hydraulic pressure in the actuator and actuator lines. The acquired data supports condition-based monitoring and maintenance practices that can significantly improve safety and performance. Real-time and historical valve data is transferred using the wellsite SCADA system. Months of data can also be saved via onboard memory and downloaded by means of RS 485, TCP/IP using Modbus or Hart communication protocols¹. Data visualization and analysis is supported using intuitive web-based software. Deployment of the mSafe controller is flexible. The low power, battery-operated control system is easily charged using wellsite power or solar panels on remote wellsites².


Conditioned-Based Monitoring

The mSafe controller’s ability to acquire and communicate precise data on even small changes in hydraulic pressure supports condition-based monitoring and maintenance in many ways: Predictive maintenance is enabled by early detection of small operational anomalies. Partial stroke testing allows diagnosis of potential valve failure without stopping production and with zero emissions. Maintenance is reduced and easier to schedule and production delays are minimized.

Management by exception and the identification of best practices benefit from mSafe data acquisition and identification of deviations. Pressure stabilization eliminates progressive valve closure and associated wear with mSafe monitoring and automatically compensating for temperature-induced variations. Line break detection identifies gradual losses in absolute pressure over time. Deviation from the pressure gradient prompts a mSafe programmable alarm or valve closure.
