Slickline PCE Control Panel (10K – 15K)
We specialize in the maintenance, redress, functional testing, and certification of Slickline Pressure Control Equipment (PCE) control panels rated for 10,000 psi and 15,000 psi service. These panels are critical to the safe and controlled operation of slickline and wireline pressure control equipment, particularly during well intervention activities where maintaining well barriers and precise hydraulic control is essential. Our services are designed to ensure dependable performance, repeatable operation, and full readiness for both onshore and offshore field use.
What is a Slickline PCE Control Panel?
A Slickline PCE control panel is the hydraulic control and monitoring center used to operate pressure control equipment such as slickline or wireline BOP rams, tool traps, and auxiliary valves. It provides the hydraulic pressure, control logic, and monitoring functions required to safely open, close, and manage these pressure-containing components during intervention operations.
A typical control panel integrates key hydraulic and control elements such as accumulators, regulators, pressure gauges, hand pumps, air-driven pumps, safety interlocks, and control valves. Together, these components provide the pressure supply and control logic needed to maintain positive well barriers and ensure safe equipment response during critical operations.
Scope of Services
Inspection and Redress
Our service begins with a full panel teardown and detailed internal inspection to evaluate the overall condition, cleanliness, and serviceability of all major components. We carry out an internal cleanliness audit to identify any contamination that could affect hydraulic performance or damage sensitive control components.
Accumulator bottles are inspected and their nitrogen pre-charge is verified to ensure correct stored energy capacity for BOP function operation. Regulators, relief valves, and check valves are overhauled and calibrated to confirm safe and accurate pressure control. We also inspect and test directional and solenoid valves, replacing seals and worn parts as needed to restore smooth and dependable operation.
Our maintenance also includes hand pumps, air-driven pumps, and related pressurization components, where seal kits are replaced and pressure output performance is checked. Filters, manifolds, tubing, hoses, and quick-connects are cleaned, inspected, leak-tested, and replaced where necessary. We also verify hose pressure ratings and apply tagging for safe identification and traceability.
For monitoring and feedback systems, gauges and transmitters are calibrated against certified references to ensure accurate readings. We also review the panel logic, verifying the correct open and close circuits for both primary and secondary barrier systems to ensure the panel functions safely and as intended.
Functional Testing
After servicing, the control panel is subjected to detailed functional testing to verify performance under operating conditions. This includes open and close cycles for each BOP function, tested at the relevant 10k or 15k psi setpoints, depending on the panel design and application.
We conduct pressure hold and pressure decay tests to confirm valve sealing integrity and circuit stability. Where interlocks or emergency shutdown systems are installed, we perform interlock and ESD verification to ensure the safety logic responds correctly.
Pump systems are tested for flow versus pressure performance, stall pressure, and any internal or external leakage. Gauge calibration checks are also recorded with as-found and as-left data, giving full visibility of instrument accuracy before and after servicing.
Certification and Documentation
Once maintenance and testing are completed, we provide a full documentation package to support operational readiness and QA/QC compliance. This can include:
- Calibration certificates
- Pressure test certificates
- Updated panel P&IDs or schematics reflecting as-built condition
- Accumulator sizing verification for required closing volumes
- Traceability records for seals, lubricants, and test media
- Detailed inspection reports, photographs, and punch lists
This level of documentation supports transparency, compliance, and confidence in the serviced equipment.
Technical Capabilities
Our technical support covers a wide range of panel configurations and operating requirements. We service panels rated for 10,000 psi and 15,000 psi, with all components selected and matched to the required pressure class.
Panels may operate with mineral hydraulic oils or water-glycol media, depending on project specifications. We support hand pump, air-driven pump, and electric pump systems for rapid and controlled pressurization. Accumulators are verified and sized to ensure they can close all required BOP functions with a suitable contingency factor.
We also support:
- High-efficiency hydraulic filtration for contamination control
- Calibrated analog gauges and optional digital transmitters
- Independent primary and secondary close circuits
- Tool-trap interlock options
- NPT, ORFS, JIC, and project-specific connection types
- Panel-to-BOP umbilical assemblies
- Skid-mounted, crash-frame, or cabinet-style enclosures
- Stainless steel or coated carbon steel construction
- Offshore-ready corrosion protection
- Optional ATEX or IECEx compatible components
Where required, panels can also be configured for HP/HT and H₂S service using compatible materials and elastomers in line with the intended operating environment.
Preventive Maintenance Program
To support reliability and reduce unplanned downtime, we recommend a structured preventive maintenance program.
Pre-deployment checks typically include function testing, accumulator pre-charge verification, and gauge confirmation.
Quarterly or duty-based maintenance may include filter replacement, leak checks, regulator setpoint verification, and pump seal inspection.
Annual servicing generally includes full redress, calibration, hose interval review, and hydraulic logic validation.
Post-event inspections are recommended after any over-pressure event, contamination issue, or control anomaly to confirm continued serviceability.
Upgrades and Options
We also provide panel upgrades and optional enhancements to improve performance, monitoring, and usability. Available options can include:
- Digital pressure and position monitoring
- Data logging for test charts and operational records
- Remote operation modules
- Wired or wireless HMI systems where permitted
- SS316 panels and enhanced corrosion-resistant tubing
- Low-temperature seal kits
- Sour-service compatible materials
- Ergonomic custom layouts
- Color-coded circuits and bilingual labeling
- Integrated test manifolds and quick-test connections
These upgrades can improve operator convenience, monitoring capability, and overall system suitability for demanding project conditions.
Safety and QA/QC
Safety and quality control are integrated into every stage of our maintenance and testing process. We apply barrier philosophy to hydraulic logic and test procedures to help ensure the panel supports safe well control practices. All instruments used during servicing and testing are calibrated and traceable to valid standards.
We also maintain hydraulic contamination control, working toward suitable cleanliness targets for hydraulic media. Our workshop and field procedures include Lockout/Tagout (LOTO), pressure-release verification, and test-bay safety controls. Full documentation is maintained throughout the process to ensure traceability, compliance, and inspection transparency.
