The Piping Stress Analysis Engineer is responsible for performing piping flexibility and stress analysis for onshore/offshore oil & gas, petrochemical, refinery and LNG projects in accordance with project specifications, international codes, and client requirements. The role ensures safe and reliable piping design while coordinating with multidisciplinary engineering teams and vendors.
Key Responsibilities- Perform piping flexibility and stress analysis using CAESAR II / AutoPIPE based on applicable project codes (ASME B31.3, B31.1, B31.4, B31.8, API, NEMA).
- Develop stress critical line list, identify critical circuits, and define stress design criteria.
- Review 3D piping models, support plans, and layouts to evaluate stress compliance.
- Define special piping components such as spring hangers, cold settings, expansion joints, anti-vibration supports, and snubbers.
- Generate piping support loads and coordinate with civil/structural team for structural & steel design inputs.
- Prepare stress reports, support sketches, load calculations, and stress isometrics.
- Review and approve vendor documents (valves, pumps, compressors, turbines, static equipment, PSV, etc.) for nozzle allowables and thermal loads.
- Resolve stress-related technical queries, deviations, and field issues raised by construction teams.
- Participate in model reviews / HAZOP / design review meetings and interact with client/PMC representatives.
- Provide construction and site assistance, including support selection and punch-list resolution.
- Ensure full compliance with project specifications, international standards, and QA/QC requirements.
Required Skills & Competencies- Strong working knowledge of CAESAR II (AutoPIPE / ROHR2 optional).
- Familiar with SP3D / E3D / PDS / Navisworks for model interpretation and mark-ups.
- Sound understanding of:
- Piping flexibility principles
- Nozzle load evaluation
- Static & dynamic load cases (thermal, slug, PSV loads, seismic, wind, vibration, water hammer)
- ASME, API, NEMA, WRC & client specifications
- Experience in high-temperature piping, rotating equipment piping, two-phase flow lines, cryogenic service (preferred).
- Knowledge of pipe support engineering, metallurgy, and material specifications is an added advantage.
Qualifications- Bachelor's Degree in Mechanical / Chemical Engineering (Master's preferred but not mandatory).
- 1116 years of experience in EPC / PMC projects for Oil & Gas, Refinery, Petrochemical, Offshore / FPSO / LNG.
- Previous experience with Oil and Gas preferred.
