mSAFE² - DUAL VALVE PRODUCTION SSV/ESD SYSTEM

Improve performance with electric-over-hydraulic emergency shutdown control system that enables condition-based monitoring and maintenance.
The mSafe² safety valve control system enhances well safety, increases operational efficiency, lowers maintenance costs and maximizes production.

ELECTRONICALLY ASSISTED HYDRAULIC CONTROL

Field-proven in Latin and North America, the mSafe² 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 2 valve positions while monitoring hydraulic pressure in the actuators 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 in onboard memory and downloaded via Modbus RS485 or Hart communication protocols.

CONDITION BASED MONITORING

The mSafe ² 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 Valve Maintenance

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.

Acuator Pressure Stabilization

Pressure stabilization eliminates progressive valve closure and associated wear with mSafe ² monitoring and automatically compensating for temperature-induced variations.

Line Break Detection

Identifies gradual losses in pressure over time preventing hydraulic releases. Deviation from the pressure gradient prompts an mSafe ² programmable alarm or valve closure.

Monitors and regulates ESD actuator pressures
