Offshore Structural Engineer

Job description

**Job Requirements** Role Summary We are looking for an FEA / Structural Integrity Engineer to support integrity engineering and life-extension assessments for upstream offshore assets — fixed and floating platforms, subsea pipelines, risers, topside piping, and pressure vessels. The role combines Risk Based Inspection (RBI), Risk Based Work Scheduling, and Fitness-for-Service (FFS) assessments with Finite Element Analysis (FEA)-based structural and mechanical evaluation to support asset life extension decisions. The candidate should be able to work across one or more of the following domains: Offshore Structures, Pipelines & Risers, Process Piping, and Pressure Vessels. Key Responsibilities (by discipline) - Offshore Structures - Structural integrity assessment of fixed offshore platforms (jackets, topsides, decks) per API RP 2A-WSD/LRFD. - In-place, fatigue, and pushover (ultimate strength) analysis of jacket structures using SACS/GT-STRUDL or equivalent. - Assessment of structural degradation, damage, and corrosion-related capacity reduction. - Life extension studies for aging offshore structures — remaining useful life estimation. - Review of metocean, seismic, and boat impact load cases as applicable to structural adequacy checks. - Pipelines & Risers - Fitness-for-Service assessment of subsea pipelines and risers per API 579-1/ASME FFS-1. - Corrosion assessment, wall-thickness evaluation, and remaining life calculation for pipelines/risers. - Riser stress analysis, span assessment, and free-span fatigue evaluation. - Support for pipeline integrity management plans, including RBI-based inspection interval optimization. - Familiarity with DNV-ST-F101/DNV-RP-F101/F108 or equivalent pipeline design/assessment codes is an advantage. - Process Piping - FFS and remaining life assessment of topside process piping systems per ASME B31.3 and API 579-1/ASME FFS-1. - Piping circuitization and Thickness Measurement Location (TML) development. - Flexibility and stress analysis using CAESAR II or equivalent. - Damage mechanism review (corrosion, erosion, fatigue) and integration into RBI studies. - Pressure Vessels & Fixed Equipment - Design and in-service evaluation of pressure vessels per ASME Section VIII Div. 1 (and Div. 2 where applicable). - FFS assessments for vessels with identified damage — local metal loss, pitting, crack-like flaws, blisters/laminations, dents. - Remaining life and re-rating calculations for in-service equipment. - Support MAWP determination and inspection interval recommendations arising from FFS outcomes. **Education** **Work Experience** - Bachelor’s/Master’s degree in Mechanical, Structural, Civil, or Naval/Offshore Engineering. **Experience** - 6–15 years of relevant experience in Oil & Gas upstream/offshore integrity engineering, structural analysis, or FFS/RBI consulting. - Prior experience with an operator, EPC, or integrity engineering consultancy serving offshore/upstream assets is preferred. **Technical Skills** - Strong working knowledge of API RP 2A (offshore structures), ASME Section VIII Div. 1 (pressure vessels), API 579-1/ASME FFS-1 (fitness-for-service), API RP 580/581 (RBI), and ASME B31.3/B31.4/B31.8 (piping/pipelines) as relevant to assigned discipline. - Hands-on FEA experience using tools such as SACS, ANSYS, Abaqus, CAESAR II, or GT-STRUDL (per discipline). - Understanding of corrosion mechanisms, damage mechanisms, materials, welding, and NDT methods. - Ability to independently perform mechanical/structural calculations and document technical assessment reports. - Exposure to offshore safety cases, HSE risk considerations, and operating philosophy of upstream facilities is a plus.
