CAC Wellhead Control Systems Control Panels

Design Overview

The CAC process control or safety shutdown panel is a fail-safe system utilizing control logic to provide 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
• BOPs
• Gas scrubbers
• Individual well control
• Well kill systems

Features

Standard CAC 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
• Removable doors for easy access to panel components
• Intrinsically safe to meet requirements such as U.L., CENELEC, BASEEFA, C.S.A., and others

Options

CAC control panels are available with a wide selection of options to insure that every condition is taken into account. The common elements from eP are exceptional quality and reliability. CAC control panels are particularly suitable for use in remote areas, on offshore platforms, and in hostile environments. Options available include:

• Single well control panels
• Multi-well control panels
• Removable well control modules
• Process control panels
• Custom designed well control panels
• Solar powered electro-hydraulic systems
