Location: Almondsbury (Bristol Area), UK (On-site) – Relocation Assistance Available!

Primary Responsibilities

• Perform piping stress analysis (static and dynamic) using tools such as AutoPIPE or CAESAR II.
• Develop stress design basis, critical line lists, and analysis procedures.
• Evaluate thermal expansion, sustained loads, occasional loads, and seismic effects.
• Provide design recommendations, including support locations and types, pipe routing optimization, and flexibility enhancements such as expansion loops and joints.
• Analyze and mitigate high piping loads on equipment nozzles (pumps, compressors, heat exchangers, tanks, and vessels), ensuring compliance with applicable codes, standards, and vendor allowable limits.
• Select appropriate spring hangers to accommodate thermal expansion and maintain acceptable piping loads.
• Generate and review stress reports, calculations, and design documentation.
• Provide pipe support load data and coordinate with pipe support engineers.
• Ensure compliance with ASME NB, ASME NCD, ASME B31.1, B31.3, and applicable project specifications.
• Review and validate third-party stress analysis.
• Coordinate with layout, materials, and structural teams for optimal designs.
• Support 3D modeling efforts, clash detection, and routing optimization.
• Assist construction teams by resolving field issues related to piping stress.

Requirements

• Bachelor’s degree in Mechanical Engineering.
• 5+ years of experience in piping stress analysis.
• Proficiency in stress analysis software such as AutoPIPE (preferred) or CAESAR II.
• Knowledge of piping design, materials, and specifications.
• Strong knowledge of ASME NB, ASME NCD, ASME B31.1 and B31.3 codes.
• Understanding of static and dynamic analysis methods.
• Experience with 3D tools such as SmartPlant 3D, PDMS, and Navisworks.
• Ability to interpret piping layouts and isometrics.
• Strong attention to detail.
• Strong reporting and documentation skills.

Preferred Qualifications

• Experience in nuclear or power plant projects.
• Knowledge of ASME B31.4 and B31.8 codes, as well as AISC and ASME Section III, NF for structural supports.
• Knowledge of HDPE and PVC piping analysis.
• Familiarity with dynamic analysis including seismic and water hammer.
• Working knowledge of pipe rupture analysis and leak-before-break is a big plus.
• Eligibility to work under 10 CFR Part 810
