Job Description

Position - Piping Stress Analysis Engineer

Division / Department: Engineering & Projects - Piping

Reporting To: Lead Piping Engineer / Project Manager

Minimum Qualifications & Experience

Education

: Bachelor's degree in mechanical engineering (Master's preferred).

Experience:

7-12 years in Oil & Gas / Petrochemical industry with specialization in piping stress
analysis.

Projects: Brownfield and Greenfield, FEED, Detailed Engineering, and EPC/EPCM projects. Standards: ADNOC Engineering Standards, ASME B31.3 (Process Piping), ASME B31.4, B31.8,
API, NEMA, ASTM, ISO, and international codes.

Job Purpose

To perform stress analysis and flexibility studies of piping systems ensuring compliance with ADNOC

standards, ASME codes, and project specifications. Deliver safe, reliable, and cost-effective designs by

mitigating piping stresses, ensuring integrity of connected equipment, and supporting project execution

from FEED through commissioning.

Key Accountabilities

1) Piping Stress Analysis

Perform static and dynamic stress analysis using CAESAR II (or equivalent) for critical piping
systems.

Evaluate sustained, operating, thermal, seismic, wind, vibration, slug flow, and blast loads. Perform nozzle load calculations on equipment (pumps, compressors, turbines, exchangers,
tanks, vessels) as per API/ASME standards.

Conduct spring hanger design, expansion loop evaluation, and support optimization.

2) Codes, Standards & Compliance

Ensure designs comply with ADNOC Engineering Standards, ASME B31.3, and client
specifications.

Check piping flexibility, allowable stresses, and load criteria per industry standards. Verify interface loads with rotating/static equipment and provide solutions.

3) Documentation & Deliverable

s

Prepare stress analysis reports, line flexibility studies, and stress-critical line lists. Develop and issue pipe support specifications, special support drawings, and vendor data review. Provide inputs to isometric drawings, piping layout, and construction deliverables.

4) Interdisciplinary Coordination

Coordinate with piping layout team, equipment, civil/structural, and process engineers for
integrated designs.

Participate in HAZOP/HAZID, 3D model reviews, and constructability workshops.

5) Site & Construction Support

Provide technical support during erection, hydrotest, and commissioning of piping systems. Assist with field modifications, NCR resolutions, and as-built documentation. Participate in site surveys, tie-in analysis, and brownfield assessments.

Skills & Competencies

Expertise in piping flexibility, load analysis, and stress engineering. Strong knowledge of ASME B31.3, piping materials, and equipment load standards (API, NEMA
SM23, API 610/617, etc.).

Ability to design cost-effective pipe supports and restraints. Strong communication, teamwork, and problem-solving skills. Familiarity with ADNOC approval workflows and authority requirements.

Software Proficiency

CAESAR II / AutoPIPE / ROHR2 - Piping stress analysis. AutoCAD / SmartPlant 3D / PDMS / E3D - Piping design and layout review. Navisworks - 3D model clash and constructability reviews. MS Office Suite - Reporting and documentation.
