We specialize in consulting, engineering, procurement and construction across the project lifecycle, with services extending through to operations and decommissioning. Leveraging extensive experience and AI-enabled delivery, we support customers in navigating complexity as they meet today's needs and transition to more sustainable solutions. Purpose: 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 estimate preparation, execution planning, and staffing forecasts for stress engineering activities. Promote safe design practices, quality compliance, continuous improvement, and effective collaboration across global execution
