Design Overview

The process control or safety shutdown panel is a fail-safe system using control logic to provide emergency shutdown (ESD), fusible loop fire protection and wellhead valve opening/closing sequencing. Standard monitoring, control and shutdown functions are available for the following applications:

• Master platform process facilities
  • ESD systems
  • Fusible loop charging systems
• Oil and gas separators
• Water injection systems
• Chemical injection systems
• Heater treaters
• Pipelines
• Gas injection systems
• Blowout preventors
• Gas scrubbers
• Individual well control
• Well kill systems

Standard control panel features:

• Sequential valve opening and closing
• Monitor flowline pressure status
• Emergency shutdown
• Manual override
• Fire safety shutdown
• Any combination of hydraulic and/or pneumatic valve actuator controls
• Remote telemetry control
• Easy serviceability
• Corrosion resistant type 316 stainless steel (SS)
• Removable doors for easy access to panel components
• Intrinsically safe to meet requirements such as ATEX, U.L., CENELEC, BASEEFA, C.S.A. and others
