Pipeline Stress Engineer

Position Overview

The Pipeline Stress Engineer performs detailed stress and flexibility analysis for subsea and offshore pipeline systems, ensuring compliance with design codes and safe operation under all loading conditions. This role is essential for the design of pipeline tie-ins, expansion loops, crossings, and riser connections. With the growing complexity of subsea tie-backs and HPHT pipeline systems, stress analysis expertise remains in strong demand.

Key Responsibilities

• Perform pipeline stress and flexibility analysis using CAESAR II, AutoPIPE, or equivalent software for subsea and offshore pipelines.
• Analyse operational, hydrotest, shutdown, and upset conditions per ASME B31.4, B31.8, DNV-OS-F101, and PD 8010.
• Design pipeline expansion loops, tie-in spools, and riser connections to accommodate thermal expansion and pressure loads.
• Perform pipeline spanning analysis and specify intervention methods (rock dump, supports) where required.
• Evaluate pipeline stability and on-bottom stability per DNV-RP-F109.
• Conduct pipeline crossing analysis and design crossing structures and protection measures.
• Review and approve stress analysis deliverables from EPC contractors.
• Provide stress analysis input to pipeline design basis and technical specifications.
• Support installation engineering with stress analysis of pipelay, pull-in, and tie-in operations.
• Assess pipeline fitness-for-service for existing pipelines under revised operating conditions.

Qualifications

Required

• Education: Bachelor's or Master's degree in Mechanical, Civil, or Pipeline Engineering
• Certifications: Chartered Engineer preferred; BOSIET/FOET for offshore visits
• Experience: 8–12 years in pipeline stress analysis for offshore pipeline systems
• Technical Skills: Proficiency in CAESAR II, AutoPIPE, or equivalent; ASME B31.4/B31.8, DNV-OS-F101, PD 8010; HPHT pipeline analysis; buckle and span assessment

Preferred

• Experience with HPHT pipeline design including lateral buckling and upheaval buckling analysis
• Knowledge of pipeline fitness-for-service assessments (API 579, BS 7910)
• Familiarity with pipeline risk and integrity management
• Involvement in subsea pipeline tie-in and commissioning engineering
