• Prepare and review engineering deliverables including:
  • Piping and Instrumentation Diagrams (P&IDs)
  • General Arrangement (GA) drawings
  • Isometrics and support details
  • Equipment layout and datasheets
  • Line lists, valve lists, and tie-in schedules
• Conduct pipe stress analysis, pressure drop calculations, and thermal expansion analysis using CAESAR II or equivalent tools.
• Ensure proper selection of materials, valves, piping components, and supports in line with process requirements and Nigerian/International codes (ASME, API, ISO, NACE, etc.).

Standards & Compliance

• Ensure all designs are compliant with:
  • Nigerian Oil & Gas Industry Content Development (NOGICD) guidelines
  • Department of Petroleum Resources (DPR) regulations
  • Relevant international codes and standards (ASME B31.3, API 610/650, etc.)
  • Client-specific specifications and quality procedures

Project Coordination & Execution

• Coordinate with process, civil/structural, instrumentation, and electrical teams for integrated project delivery.
• Interface with vendors and third-party contractors to ensure engineering specifications are met.
• Participate in design reviews, model reviews (3D), HAZOPs, and constructability assessments.
• Ensure timely delivery of engineering documents and support project controls in schedule and cost tracking.

Team Leadership & Mentorship

• Supervise and mentor junior engineers and designers.
• Allocate design tasks and ensure quality, accuracy, and completeness of deliverables.
• Conduct internal technical audits and peer reviews.
• Promote HSE best practices in all engineering activities.

Client & Stakeholder Management

• Serve as the primary technical contact for clients on mechanical/piping scope.
• Attend client meetings, provide technical presentations, and support project proposals or bidding efforts.
• Prepare and submit technical reports, method statements, and design philosophies.

QUALIFICATION & EXPERIENCE

• Education: B.Eng / B.Sc. in Mechanical Engineering from an accredited university (M.Sc. an advantage).
• Professional Certification: COREN registration is mandatory; membership of NSE, ASME, or API is a plus.
• Experience: Minimum 8 years of relevant experience in oil and gas design engineering, with at least 5 years in a lead or principal engineering role on major projects in Nigeria or West Africa.

Software Proficiency:

• CAESAR II (Pipe Stress)
• AutoCAD / Plant 3D / PDMS / E3D / Navisworks
• Microsoft Office, Bluebeam or other markup tools

Skills & Competencies:

• Strong understanding of oil & gas field development, pipelines, FPSOs, flow stations, refineries, and modular skids.
• Deep expertise in mechanical equipment design and piping layout best practices.
• Leadership and team-building skills with a focus on mentorship.
• Excellent written and verbal communication.
• Strong analytical and problem-solving ability.
• Ability to work in multi-cultural, multi-disciplinary project teams.
• Willingness to travel to site locations and project offices as required.
