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.
Manual, remote and automated operations
Implement condition-based monitoring and maintenance using valve status data communicated via SCADA, telemetry or downloaded from onboard memory
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
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
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
programmable alarm or valve closure.
Monitors and regulates ESD actuator pressures
