What this role is
Experienced professional who optimizes and troubleshoots refinery process units to ensure safe, efficient production. At the Senior Professional (P4) level, the role owns a system or set of related features, devises new approaches, and drives multi-team / function outcomes. Technical lead for focused efforts; mentors several.
What this level does
- Serve as the senior operator across multiple interdependent units, resolving complex operating conflicts (e.g., competing heat, hydrogen, or utility demands) that affect unit-block performance
- Coordinate emergency responses across units — trip logic, ESD actions, depressurization, flare routing — and author safe recovery sequences
- Select operating methods and improvised procedures for abnormal situations not covered by standard SOPs, drawing on in-depth analysis of process behavior
- Lead unit transitions and major campaigns (turnaround start-ups, feed slate changes), directing and mentoring less experienced operators through the sequence
- Analyze recurring upsets and yield gaps, drive corrective/preventive process changes, and coordinate across shift, maintenance, and engineering groups
- Knowledge applied
- Applies in-depth process expertise across multiple interdependent units, improvising sound procedures where SOPs do not fully apply.
- Complexity & problem solving
- Performs in-depth analysis of complex, interacting variables during multi-unit upsets and campaigns; selects methods and leads recovery.
- Collaboration & interaction
- Coordinates across shift, maintenance, and engineering groups; influences operating decisions and mentors senior operators.
- Typical experience
- 8+ years; qualified across a unit block with demonstrated leadership on transitions and emergencies.
Skills at this level
- Operations Monitoring
- — Watches gauges, dials, and DCS display screens to confirm process equipment is running and to detect off-target pressure, temperature, level, and flow before they breach alarm limits.
- DCS/PLC Control-System Operation
- — Safely and efficiently operates refinery process units through a DCS/PLC control-room interface — making setpoint changes, managing control modes, and acknowledging alarms.
- Advanced Process Control Management
- — Configures and operates cascade, ratio, and split-range control loops and tunes them within the unit's operating envelope to hold product on spec.
- Unit Transition Execution
- — Carries out start-up, shutdown, and unit transitions — cool-down, heat-up, line-up, decoking/regeneration, and feed switchovers — following approved sequences.
- Process Unit Knowledge
- — Applies working knowledge of refinery unit operations including distillation, cracking, reforming, blending, and treating to run and adjust the process.
- Product Quality Validation
- — Confirms product quality using on-line analyzers and lab results and adjusts cut points, reflux, reboiler duty, and hydrogen rates to bring streams into specification.
- Emergency Response & Shutdown Handling
- — Coordinates trip logic, ESD actions, depressurization, and flare routing during upsets and issues safe recovery steps for the unit.
- Lockout/Tagout (LOTO) & Field Safety
- — Follows LOTO isolation and field safety procedures when sampling, isolating equipment, or supporting maintenance to prevent uncontrolled energy release.
- Process Troubleshooting
- — Diagnoses process upsets and yield gaps by evaluating feed quality, heat balance, catalyst condition, and equipment behavior, then selects corrective actions.
- Crude-Slate Optimization
- — Uses refinery optimization tools to adjust crude slates and unit operation in response to system, supply, or market fluctuations to maximize refinery contribution.
- Mechanical Aptitude
- — Applies knowledge of pumps, valves, exchangers, and related machines and tools — their uses, and basic maintenance needs — to operate and safely isolate field equipment.
- Continuous Improvement
- — Applies structured continuous-improvement approaches to refine operating workflows and procedures for better output, quality, and reliability.
- Shift Supervision & Coordination
- — Directs and coordinates the activities of production and operating workers across a shift, resolving operating conflicts and leading recovery efforts.
