Principal Piping Engineer; Material and Stress

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

Provide senior technical leadership and discipline authority for piping engineering with a primary focus on piping stress analysis, pipe supports and piping materials engineering, ensuring safe, code-compliant and economical designs.

Lead and coordinate piping engineering activities across the full project lifecycle (Concept/FEED, Detailed Engineering, Procurement support, Construction support and Commissioning) in an EPC/EPCM environment.

Own technical integrity for stress analysis deliverables (critical line management, support philosophy nozzle loads, civil loading, vibration/dynamic assessment) and materials deliverables (PMS/line classes, datasheets, MTO/MR/TBE, vendor document review and traceability).

Key Accountabilities & Responsibilities

HSE, SEAL & Safety in Design

• Demonstrate visible and active commitment to HSE leadership on projects; promote safe behaviors and ensure discipline compliance with project and corporate requirements.
• Drive Safe and Sustainable Engineering outcomes by participating in SEAL alignment and hazard/risk assessment workshops; ensure piping inputs support safe operability and lifecycle thinking.
• Apply Safety in Design principles (ALARP / hierarchy of controls) within piping engineering and ensure hazards/risks are identified, documented and managed through design and reviews.

• Plan, organize and manage all aspects of piping engineering workload for one major project or multiple projects concurrently.
• Establish and maintain discipline deliverables register; control, monitor and progress deliverables to agreed schedule; provide timely status reporting.
• Manage resource requirements for piping (including dedicated stress and materials resources); coordinate staffing and skills needs with engineering/discipline management.
• Coach, mentor and technically supervise assigned engineers/designers; provide technical escalation, capability development and effective supervision.
• Ensure communication flow, both verbal and written, is maintained within piping and with other engineering disciplines.

• Define project stress philosophy/criteria and analysis approach; determine the need for computer stress analysis based on project guidelines and code requirements.
• Produce and maintain stress deliverable controls such as Critical Line List and Stress Sketch / Register; ensure stress status/approvals are captured for construction isometrics as required.
• Review and approve piping stress models, calculations and reports; ensure compliance with project-adopted codes/standards and alignment when software code edition differs from project code edition.
• Develop, review and approve pipe support requirements including support selection philosophy, special support lists, and interface requirements for structural design.
• Ensure timely and accurate piping load transmittals to Civil/Structural (anchor/guide/support loads, nozzle loads, and other required load cases) and lead cross-discipline coordination to close interfaces.
• Assess and manage vibration and dynamic effects (e.g., surge/slug, rotating equipment, relief valve reaction, wind/seismic as applicable) and define mitigation actions through layout/support optimisation.
• Support troubleshooting of stress issues, constructability constraints and field changes; provide engineering judgement to achieve safe, practical and cost-effective solutions.

• Lead development and governance of Piping Material Specifications (PMS) / Line Class Index and associated specifications; ensure alignment with process/service requirements and applicable codes/standards.
• Oversee preparation and…
