Principal Piping Designer

Overview

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.

• Leadership, Planning & Team Supervision

• 3D Modeling & Layout Execution (Primary)

• 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)

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.
