Job Posting

Unposting Date: Ongoing

Reporting Manager Title : Senior Manager, Piping Engineer

Role Purpose

• Lead and deliver piping design and SP3D modeling outputs for assigned area(s)/package(s), ensuring safe, compliant, constructible and coordinated layouts in line with project specifications, client standards and applicable codes.
• Act as the focal point for piping design execution within the design team—planning, allocating and supervising designer workloads; driving model quality, drawing quality, and on‑time delivery to project milestones.
• Support Piping Engineering (stress and materials) by ensuring designs incorporate stress and material requirements (support locations, flexibility provisions, line classes/material selections) and by coordinating interfaces with Civil/Structural, Mechanical, Process and E&I.

Key Accountabilities & Responsibilities

• Leadership, Planning & Team Supervision
  • Plan and manage day‑to‑day piping design workload for the assigned area(s), including resource allocation, priorities, and short‑interval planning aligned to the project schedule.
  • Supervise, mentor and guide designers/modelers; ensure consistent application of project drafting/modeling standards and quality expectations.
  • Conduct checking/back‑checking of key deliverables (3D model, GAs, isometrics, support location plans, MTOs) and ensure comments are closed out before issue.
  • Coordinate with Piping Lead Engineer/Area Lead on technical priorities, design constraints, holds/assumptions, and interface risks impacting delivery.
• 3D Modeling & Layout Execution (Primary)
  • Lead development and maintenance of piping SP3D model for assigned scope: equipment modeling support (as required), pipe routing, tie‑in modeling, and support modeling consistent with project practices.
  • Drive layout quality: safe access/egress, maintainability, operability, constructability, lifting/handling clearances, and compliance with separation distances and safety requirements.
  • Participate in internal and client model reviews (e.g., 30/60/90%); lead design closeout actions and ensure timely update of model and drawings.
  • Coordinate clash detection and resolution with other disciplines and consolidate piping design actions to meet milestones.
• Drawing & Deliverable Production
  • Develop and check piping deliverables including plot plans (where applicable), piping general arrangement drawings, key plans, piping plans, and demolition/installation drawings as required.
  • Lead extraction, checking and issue of piping isometrics (IFR/IFC) aligned to fabrication/construction priorities; ensure completeness of line data, supports, welds, spools and annotations as per project requirements.
  • Prepare and check piping MTOs (bulk, valves, special items) and construction MTOs as required; support weight/dia‑inch reporting and other model‑based reporting.
  • Coordinate production of pipe support deliverables: support location plans, standard support references, and special support sketches/inputs to engineering.
• Interface with Stress, Materials & Engineering (Support)
  • Coordinate with stress engineers to ensure routing provides required flexibility and to implement stress markups, support/restraint locations, and critical line requirements.
  • Coordinate with materials engineers/engineers to ensure correct line classes and material selections are implemented in the model and reflected in isometrics and MTOs.
  • Provide design inputs to Civil/Structural for pipe support loads/interfaces (as directed by piping engineering) and ensure model support points are consistent with agreed formats and procedures.
  • Support vendor document reviews and package interfaces by integrating vendor GA/nozzle information into the model and updating layouts accordingly.
• Quality, Governance & HSE
  • Ensure piping design outputs comply with project quality plan, discipline procedures, and drawing/model checking requirements.
  • Promote safe design practices in layouts (hazard avoidance, safe access, maintainability) and participate in constructability/HAZID/HAZOP and design review workshops as required.
  • Maintain good document control practices and ensure design changes are properly recorded and reflected in deliverables.
• Construction / Site Support (as assigned)
  • Support construction and site teams by responding to design queries, assisting with tie‑in walkdowns, and incorporating approved field changes into model/drawings.
  • Support generation of workpacks / installation sketches / as‑built updates where required by the contract and project procedures.
• Typical Deliverables (Examples)
  • 3D piping model (clash‑free, coordinated) with supports and line classes applied.
  • Plot plans / key plans / GA drawings / piping plans.
  • IFR/IFC piping isometrics and isometric index.
  • Pipe support location plans and special support sketches/inputs.
  • MTOs (bulk, valves, specialty items) and construction MTOs.
  • Model review closeout reports and design issue registers.

Core Competencies

• Strong leadership and supervision of piping designers; ability to drive quality and schedule in a high‑volume deliverables environment.
• Advanced piping layout and 3D modeling expertise (equipment areas, racks, modules, brownfield tie‑ins).
• Strong understanding of constructability, access, maintenance and safety requirements in layout.
• Effective coordination and communication across disciplines and with vendors/clients.
• Attention to detail, strong checking mindset, and commitment to continuous improvement.

Preferred / Advantageous

• ADNOC AGPS / ADNOC Offshore/Onshore layout and drafting practices exposure.
• Experience on GCC mega projects and multi‑office execution / workshare environments.
• Familiarity with Worley Management System / Knowledge System expectations for checking, reviews and document control.

Minimum Qualifications & Experience

• Diploma / Degree in Mechanical Engineering or equivalent discipline qualification with extensive piping design experience.
• 20+ years total piping design experience in Oil & Gas / Energy / Process industries.
• 15+ years detailed engineering / detailed design experience (SP3D model + IFC production).
• 10+ years offshore design experience (must‑have), including topsides / offshore facilities and brownfield modifications. Proven capability to lead a team of designers (planning, supervision, checking, mentoring and performance support).
• Strong working knowledge of SP3D design tools and drawing production workflows (project‑approved toolset).
• ADNOC standards awareness is an advantage; familiarity with Worley systems and work processes is a plus; GCC experience is a plus.
