Principal Piping Designer

Building on our past. Ready for the future

Worley is a global professional services company of energy chemicals and resources experts. We partner with customers to deliver projects and create value over the life of their assets. Were bridging two worlds moving towards more sustainable energy sources while helping to provide the energy chemicals and resources needed now.

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 teamplanning 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 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.
