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. We’re 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 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 ve
