Reports to: Manager, Concept Development
Job Summary
To execute process engineering activities for new facilities, existing facilities modifications and operational support, for the Engineering and Operations departments, to ensure safe, reliable, and efficient hydrocarbon processing that safeguards personnel and optimizes asset performance and profitability.
Key Responsibilities Areas (KRAs) and Initiatives
Process Design and Engineering Excellence
- Develop, verify, and document heat and material balances, fluid hydraulics, and equipment sizing calculations using process simulation software e.g. Aspen suite, Pipesim, Olga to ensure accurate specifications, reliable equipment procurement, and efficient, safe facility operation that maximizes production output.
- Prepare, review, and approve process engineering deliverables including Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), and equipment datasheets to ensure technical accuracy, compliance with industry standards, and seamless integration with multi-disciplinary engineering designs that minimizes rework and project delays.
- Lead the development and update of standard engineering specifications and design philosophies by incorporating industry best practices (e.g., API, ASME standards) and lessons learned to ensure consistent, high-quality design practices that enhance asset integrity and reduce operational risk.
- Conduct concept engineering studies and feasibility assessments for new facilities, proposed facility modifications by evaluating technical options, estimating costs, and defining project scopes to provide sound recommendations that support robust project planning and effective capital allocation decisions.
- Manage the technical aspects of equipment procurement by participating in vendor technical evaluations, reviewing vendor drawings, and addressing clarification queries to ensure purchased equipment meets all process requirements, performs reliably, and complies with safety standards that support project timelines and operational goals.
Operational Support and Optimization
- Conduct steady-state and transient flow assurance simulations. Manage wax, hydrate, asphaltene, and scale prevention/remediation. Monitor and troubleshoot multiphase flow behavior and slugging. Provide operational support for well startups, pigging, and pipeline events. Identify and eliminate flowline and pipeline system bottlenecks.
- Optimize and improve oil and gas separation processes to reduce liquid carryover and gas entrainment. Improve produced water treatment and oil‑in‑water quality. Ensure crude stabilization meets RVP and export quality specs. Resolve foaming, emulsions, sand production, and separation upsets. Investigate and correct process trips, alarms, or equipment instability.
- Optimize gas sweetening and dehydration units, Improve NGL recovery, fractionation, and overall plant yields. Monitor and troubleshoot gas compression performance. Ensure export gas meets heating value and contaminant specifications. Support accurate gas metering and fiscal measurement activities.
- Track plant KPIs and identify process improvement opportunities, conduct energy optimization and cost-reduction studies. Support management of change activities, participate in HAZOP, SIL and process safety reviews
- Manage fuel gas, fuel systems and emission compliance, oversee water, steam and cooling utilities for stable operations. Optimize chemical injections and ensure correct dozing. Ensure reliable instrument air, nitrogen and utility gas systems Maintain update operating manuals, Process documentation and drawings.
Process Safety and Risk Management
- Lead process safety in design, identifying hazards associated with flow assurance systems, gas processing plants, separation units, and utility systems
- Maintain and periodically review the Safe Operating Limits, design envelopes, and critical process parameters for flowlines, compressors, dehydration units, amine systems, separators, and utility packages.
- Execute technical assurance of all process-related changes. Through the MoC process, the engineer assesses the safety implications of plant modifications, temporary bypasses, chemical changes, or procedural updates related to gas plants, separation trains, or utility systems.
- Lead process safety within flow assurance includes ensuring safe start-up, shutdown, and pigging operations, as well as managing risks from hydrate formation, overpressure, wax deposition, and multiphase slugging
- Lead process safety within separation systems, the engineer manages safety risks associated with high pressure drops, liquid carryover, foam formation, sand accumulation, and unstable levels.
Technical Leadership and Mentorship
- Provide expert-level technical leadership across flow assurance, oil and gas processing, pipeline systems and process utilities.
- Lead peer assists reviews, and assurance sessions for projects and operational activities involving flowlines, gas plants, separation trains, or utility packages.
- Act as technical authority for resolving complex operational challenges. Provide real‑time decision support during plant upsets, flow disruptions, equipment failures, or process safety events.
- Serve as the technical focal point in meeting with the operations, maintenance, production, and integrity team as well as external vendors.
- Identify opportunities to adopt new technologies, tools and methodologies that improve operational efficiency or enhance technical capabilities.
Compliance and Standards Adherence
- Ensure pipeline, flowlines and process system design follow applicable company and international standard codes. Verify hydrate, wax, scale, and asphaltene management strategies meet safety and design standards. Ensure pigging and depressurization procedures comply with safety and operational standards
- Maintain updated lists of applicable standards (API, ASME, ISO, NACE, NFPA, local regulations). Conduct gap assessments to identify non‑compliance and recommend corrective actions.
- Ensure amine systems, dehydration units, NGL recovery, and compression systems meet design codes. Validate relief valve sizing, flare design, and emergency shutdown logic against standards.
- Ensure separators, heater treaters, and crude stabilization units meet performance and design standards. Verify produced water treatment meets environmental discharge limits. Monitor crude export quality (BS&W, RVP) for regulatory and contract compliance.
- Ensure Management of Change (MoC) includes standards impact checks and updated documentation. Control engineering documents through proper revision and audit processes
