Specialist Piping Engineer – Offshore Water Injection Project

Specialist Piping Engineer – Offshore Water Injection Project Overview

Job Purpose:

The Specialist Piping Engineer leads piping engineering activities for offshore water injection facilities, ensuring safe, reliable, and cost‑effective design, installation, and integration of piping systems within existing offshore infrastructure. The role supports FEED, detailed engineering, procurement, construction, commissioning, and brownfield modification activities while ensuring compliance with project specifications, ADNOC requirements, and international standards.

• Lead piping design and engineering activities for offshore water injection systems:
  • Develop and review piping specifications, material classes, datasheets, and design philosophies.
  • Review and approve piping layouts, GA drawings, isometrics, and 3D models.
  • Ensure piping systems are designed for operability, maintainability, safety, and constructability.
  • Perform piping routing studies considering space constraints and brownfield integration requirements.
  • Support line sizing, pressure drop calculations, and hydraulic assessments.
• Stress Analysis & Flexibility:
  • Review piping stress analyses and flexibility studies.
  • Ensure compliance with code requirements for thermal expansion, vibration, and operational loads.
  • Coordinate with stress engineers to resolve high‑stress and support issues; review critical line support arrangements and expansion solutions.
• Material & Corrosion Management:
  • Define piping material specifications for seawater, treated water, and utility systems.
  • Assess corrosion risks and recommend mitigation measures; ensure material selection complies with process requirements and design life expectations.
  • Review corrosion allowance requirements and protective coating specifications.
• Brownfield & Offshore Modifications:
  • Conduct offshore site surveys and brownfield assessments.
  • Develop tie‑in strategies and piping modification plans; support shutdown planning and SIMOPS activities.
  • Evaluate existing facilities to identify integration challenges; minimize impact on ongoing production operations.
• Multidisciplinary Coordination:
  • Coordinate with Process, Mechanical, Structural, Instrumentation, Electrical, and Operations teams to resolve design clashes and interface issues.
  • Participate in design reviews, constructability workshops, and model reviews; provide technical guidance to design and drafting teams.
• Procurement & Vendor Support:
  • Prepare material requisitions and technical specifications.
  • Support bid evaluations and vendor selection processes; review vendor package piping interfaces and integration requirements.
  • Resolve technical queries related to piping materials and fabrication.
• Construction & Commissioning Support:
  • Provide engineering support during fabrication, installation, testing, and commissioning.
  • Review construction work packs and method statements; support hydro‑testing, flushing, cleaning, and mechanical completion activities.
  • Resolve field engineering queries and non‑conformance reports; verify system readiness for commissioning and startup.
• HSE & Quality Compliance:
  • Participate in HAZID, HAZOP, constructability, SIMOPS, and risk assessment studies.
  • Ensure compliance with project HSE requirements and company standards; support MOC processes.
  • Promote safe design principles and asset integrity throughout the project lifecycle.

• Bachelor's Degree in Mechanical Engineering or equivalent discipline.
• Master's Degree is an advantage.
• Chartered Engineer (CEng) or equivalent professional certification preferred.
• 15–18 years of piping engineering experience within the Oil & Gas industry.
• Minimum 5 years of experience in offshore brownfield EPC projects.
• Strong experience in offshore water injection, produced water, utilities, and process piping systems.
• Proven involvement in FEED, detailed engineering, procurement, construction, commissioning, and startup phases.
• ADNOC Offshore and Middle East project experience highly preferred.
• Experience with offshore islands, platforms, and shutdown/tie‑in projects is desirable.

• Piping Design – Offshore Process Piping, Water Injection Systems, Utility & Produced Water Networks, Piping Layout Development, Tie‑In Engineering, Material Selection, Constructability Reviews, Piping Analysis, Stress Analysis, Flexibility Assessment, Vibration Analysis, Pipe Support Design, Hydraulic Evaluation.
• Codes & Standards – ASME B31.3, ASME B31.4 / B31.8, API, ASTM, NACE, ISO, ADNOC Specifications, Shell DEP / International Oil & Gas Practices.

• CAESAR II, AutoPIPE, AVEVA E3D, SP3D (Smart Plant 3D), AutoCAD Plant 3D, Navisworks, Smart Plant Review, MS Office Suite, K  — Delivering Solutions platform.
