As a Principal Pipe Stress Engineer at Worley, the successful candidate will be part of a worldwide team that delivers excellent project services to customers globally. The successful candidate is responsible for ensuring that piping systems are safe, code-compliant, operable, and constructible by evaluating stresses, flexibility, support requirements, and equipment loads throughout the project lifecycle.

• Understand and comply with company, department, and project procedures, and ensure their consistent application throughout project execution.
• Ensure compliance with applicable industry codes, standards, and client specifications, including ASME, API, PIP, and project-specific requirements.
• Lead and execute piping stress analysis activities for FEED, detailed design, brownfield, and greenfield projects.
• Perform piping flexibility and stress analyses using CAESAR II and other applicable software tools to ensure compliance with project specifications, design codes, and client requirements.
• Develop stress-critical line lists, calculation indexes, stress calculations, and engineering deliverables throughout the project lifecycle.
• Review piping layouts and provide recommendations to optimize routing, flexibility, support arrangements, and equipment load compliance.
• Evaluate thermal expansion, weight, pressure, wind, seismic, slug flow, fluid hammer, PSV discharge, and other sustained, occasional, and dynamic loading conditions.
• Perform nozzle load qualification and interface with mechanical equipment suppliers to ensure compliance with allowable equipment loads.
• Provide pipe support design guidance, including spring supports, restraints, snubbers, expansion joints, and specialty support systems.
• Coordinate closely with piping designers to resolve stress concerns and develop practical, constructible piping layouts.
• Review and approve stress calculations, support sketches, stress dossiers, and associated engineering deliverables prepared by other engineers.
• Lead multidisciplinary coordination with Mechanical, Structural, Civil, Process, Project Controls, Procurement, and Construction teams.
• Participate in model reviews, design reviews, HAZOPs, constructability reviews, and client technical reviews.
• Support procurement activities through technical bid evaluations, vendor document reviews, and resolution of technical queries.
• Provide construction support by reviewing RFIs, field changes, stress-related site issues, and commissioning concerns.
• Lead acoustic-induced vibration (AIV) and flow-induced vibration (FIV) screening and assessments for relief systems, gas-service piping, compressor systems, and high-energy process piping, where required.
• Identify vibration risks and develop mitigation measures associated with control valves, restriction orifices, pressure letdown stations, and relief devices.
• Mentor and develop junior and intermediate stress engineers through technical coaching, workshare coordination, and engineering reviews.
• Serve as the project focal point for piping stress engineering and provide regular progress reporting to project management and discipline leadership.
• Support proposal development, man-hour estimates, basis of…
