- Perform piping stress analysis using recognised industry software (e.g., CAESAR II / AutoPIPE).
- Evaluate nozzle loads, support loading, thermal expansion, vibration issues, and system flexibility.
- Conduct static and dynamic analyses, ensuring systems meet functional, safety, and engineering design requirements.
- Design & Technical Review
- Review and validate piping designs, GA drawings, and engineering deliverables.
- Assess and sign off piping isometrics, ensuring flexibility, routing, and support requirements are met.
- Provide input into the design of pipe supports, integrating stress requirements and project specifications.
- Review 3D models for compliance, constructability, clash management, and adherence to stress reports and codes.
- Documentation & Compliance
- Produce, check, and maintain detailed documentation including stress reports, calculations, engineering specifications, technical assessments, and design justifications.
- Ensure all deliverables comply with applicable nuclear standards, codes (ASME, BS/EN), safety requirements, and project procedures.
- Support internal and external reviews, audits, and technical queries.
- Collaboration & Project Delivery
- Work closely with piping, mechanical, civil, process, and safety engineering teams.
- Support project planning, change control, and design risk assessments.
- Engage with stakeholders, including clients, regulators, and construction teams, ensuring a clear understanding of stress engineering requirements.
Required Experience
- Proven experience as a Piping Stress Engineer within nuclear, petrochemical, energy, or similar highly regulated sectors.
- Strong understanding of piping design principles, flexibility analysis, and piping system behaviour under operational loads.
