Oil & Gas Automation & Control Systems Engineering

Process safety is foundational to US industrial operations. We deliver end-to-end functional safety lifecycle engineering adhering strictly to IEC 61508, IEC 61511, and ISA-84 standards to protect human life, production infrastructure, and local ecosystems.

• Emergency Shutdown Systems (ESD): Configuration and validation of dedicated safety logic solvers engineered to initiate fail-safe isolation, de-pressurization, and blowdown profiles during critical overpressure or thermal anomalies.
• Fire & Gas Systems (F&G): Meticulous zoning, integration, and logic deployment for safety arrays, matching advanced optical flame detection, toxic/combustible gas monitoring, and ultrasonic leak sensors with automatic deluge or active suppression triggers.
• High-Integrity Pressure Protection Systems (HIPPS): Specialized design of safety loops intended to isolate downstream piping overpressure conditions, serving as a critical protection layer that eliminates the dependency on traditional atmospheric relief valves.

We bridge the operational gap between conceptual capital expenditure planning and physical field execution by generating robust, construction-ready engineering packages. Our multidisciplinary engineering teams utilize industry-standard design tools to ensure precision and prevent field modifications.

• Instrumentation & Loop Detailing: Generation of comprehensive Input/Output (I/O) maps, instrument datasheets, functional schematics, and individual Instrument Loop Diagrams mapping out complete signal pathways from field sensors to marshalling cabinets and logic solvers.
• Piping & Process Drafting Validation: In-depth validation and markup of Process Flow Diagrams (PFDs) and Piping and Instrumentation Diagrams (P&IDs) against live controller configurations to ensure structural, hydraulic, and process integrity.
• Electrical Interface & Control Panel Layouts: Structural panel design optimizing internal component spacing, thermal ventilation, diode safety barriers, relay logic, and direct Motor Control Center (MCC) electrical interfaces.

Operating with obsolete control infrastructure significantly compromises cybersecurity posture, introduces spare-parts supply risks, and caps operational efficiency. We provide non-disruptive, phased migration pathways designed to maximize existing investment while updating the facility’s technological core.

• System Vulnerability & Assessment: Comprehensive hardware, software, and industrial network code reviews to locate capacity constraints, identify components approaching end-of-life (EOL), and formulate risk-mitigated upgrade roadmaps.
• Hot Cutover & Migration Planning: Meticulous execution strategies mapping out data structure transfers, logic conversion from legacy scripts to modern IEC 61131-3 languages, and physical loop cutovers scheduled tightly to minimize or completely eliminate facility downtime.
• HMI & SCADA Modernization: Total re-engineering of operator interfaces using high-performance, situational awareness guidelines (ISA-101) to maximize operator responsiveness, clear cognitive clutter, and improve real-time alarm handling.

For aging production assets where original engineering manuals, functional specifications, or electrical wiring prints are missing or inaccurate, our specialists restore complete operational clarity.

• Controller Code De-compilation & Extraction: Extracting and analyzing operational logic straight from active PLC/DCS backups across complex Multi-Controller Networks to compile accurate, modern Functional Design Specifications (FDS) and Control Narratives.
• As-Built Infrastructure Restoration: Physical validation of field wiring networks, junction box terminations, and communication link routing to construct comprehensive, current As-Built schematics, instrument cable schedules, and network architectural layouts.

Achieving and defending a target Safety Integrity Level 3 (SIL 3) configuration demands exhaustive analytical precision across every component of the safety instrumented function (SIF) loop. We provide objective, credentialed consultancy services guiding teams through the complete safety lifecycle.

• Quantitative Loop Verification Modeling: Utilizing specialized platform software, such as exSILentia, to execute precise Failure Modes, Effects, and Diagnostic Analysis (FMEDA) and Probability of Failure on Demand (PFD) mathematical calculations.
• Risk Evaluation & Matrix Validation: Authoritative engineering reviews of previous Process Hazard Analysis (PHA) data, Hazard and Operability (HAZOP) studies, and Cause-and-Effect (C&E) matrices to confirm the adequacy of independent protection layers.
• Operational Validation Protocol Authoring: Formulating explicit Safety Requirements Specifications (SRS) alongside actionable, verifiable field proof-testing and predictive maintenance protocols to defend loop integrity over decades of service.

Safe and precise long-distance transportation of crude oil, natural gas, and refined petroleum fluids requires highly integrated control, communication, and measurement systems.

• LACT Engineering & Custody Transfer Metering: Designing and integrating certified custody transfer metering packages, Lease Automatic Custody Transfer (LACT) skids, and flow computer logic that strictly comply with API (American Petroleum Institute) and AGA (American Gas Association) standards for precise volume and energy transactions.
• Leak Detection Systems (LDS) & Hydraulic Modeling: Integrating advanced real-time pipeline monitoring solutions with external transient flow models to quickly identify, isolate, and pinpoint structural pressure loss or product leaks.
• Terminal Automation Systems (TAS): Implementing high-efficiency loading and unloading rack controllers, automated tank gauging (ATG) arrays, inventory ledger reconciliation engines, and access security barriers to optimize distribution hub turnaround.
